# Description |
|||
|
|||
## Primary Features |
|||
|
|||
By design, RomWBW isolates all of the hardware specific functions in the |
|||
ROM chip itself. The ROM provides a hardware abstraction layer such that |
|||
all of the operating systems and applications on a disk will run on any |
|||
RomWBW-based system. To put it simply, you can take a disk (or CF/SD/USB |
|||
Card) and move it between systems transparently. |
|||
|
|||
Supported hardware features of RomWBW include: |
|||
|
|||
- Z80 Family CPUs including Z80, Z180, and Z280 |
|||
- Banked memory services for several banking designs |
|||
- Disk drivers for RAM, ROM, Floppy, IDE ATA/ATAPI, CF, SD, USB, Zip, |
|||
Iomega |
|||
- Serial drivers including UART (16550-like), ASCI, ACIA, SIO |
|||
- Video drivers including TMS9918, SY6545, MOS8563, HD6445, Xosera |
|||
- Keyboard (PS/2) drivers via VT8242 or PPI interfaces |
|||
- Real time clock drivers including DS1302, BQ4845 |
|||
- Support for CP/NET networking using Wiznet, MT011 or Serial |
|||
- Built-in VT-100 terminal emulation support |
|||
|
|||
A dynamic disk drive letter assignment mechanism allows mapping |
|||
operating system drive letters to any available disk media. |
|||
Additionally, mass storage devices (IDE Disk, CF Card, SD Card, etc.) |
|||
support the use of multiple slices (up to 256 per device). Each slice |
|||
contains a complete CP/M filesystem and can be mapped independently to |
|||
any drive letter. This overcomes the inherent size limitations in legacy |
|||
OSes and allows up to 2GB of addressable storage on a single device, |
|||
with up to 128MB accessible at any one time. |
|||
|
|||
## Included Software |
|||
|
|||
Multiple disk images are provided in the distribution. Most disk images |
|||
contain a complete, bootable, ready-to-run implementation of a specific |
|||
operating system. A “combo” disk image contains multiple slices, each |
|||
with a full operating system implementation. If you use this disk image, |
|||
you can easily pick whichever operating system you want to boot without |
|||
changing media. |
|||
|
|||
Some of the included software: |
|||
|
|||
- Operating Systems (CP/M 2.2, ZSDOS, NZ-COM, CP/M 3, ZPM3, Z3PLUS, QPM |
|||
) |
|||
- Support for other operating systems, p-System, FreeRTOS, and FUZIX. |
|||
- Programming Tools (Z80ASM, Turbo Pascal, Forth, Cowgol) |
|||
- C Compiler’s including Aztec-C, and HI-TECH C |
|||
- Microsoft Basic Compiler, and Microsoft Fortran |
|||
- Some games such as Colossal Cave, Zork, etc |
|||
- Wordstar Word processing software |
|||
|
|||
Some of the provided software can be launched directly from the ROM |
|||
firmware itself: |
|||
|
|||
- System Monitor |
|||
- Operating Systems (CP/M 2.2, ZSDOS) |
|||
- ROM BASIC (Nascom BASIC and Tasty BASIC) |
|||
- ROM Forth |
|||
|
|||
A tool is provided that allows you to access a FAT-12/16/32 filesystem. |
|||
The FAT filesystem may be coresident on the same disk media as RomWBW |
|||
slices or on stand-alone media. This makes exchanging files with modern |
|||
OSes such as Windows, MacOS, and Linux very easy. |
|||
|
|||
## ROM Distribution |
|||
|
|||
The [RomWBW Repository](https://github.com/wwarthen/RomWBW) |
|||
(<https://github.com/wwarthen/RomWBW>) on GitHub is the official |
|||
distribution location for all project source and documentation. |
|||
|
|||
RomWBW is distributed as both source code and pre-built ROM and disk |
|||
images. |
|||
|
|||
The pre-built ROM images distributed with RomWBW are based on the |
|||
default system configurations as determined by the hardware |
|||
provider/designer. The pre-built ROM firmware images are generally |
|||
suitable for most users. |
|||
|
|||
The fully-built distribution releases are available on the [RomWBW |
|||
Releases Page](https://github.com/wwarthen/RomWBW/releases) |
|||
(<https://github.com/wwarthen/RomWBW/releases>) of the repository. |
|||
|
|||
On this page, you will normally see a Development Snapshot as well as |
|||
recent stable releases. Unless you have a specific reason, I suggest you |
|||
stick to the most recent stable release. |
|||
|
|||
The asset named RomWBW-vX.X.X-Package.zip includes all pre-built ROM and |
|||
Disk images as well as full source code. The other assets contain only |
|||
source code and do not have the pre-built ROM or disk images. |
|||
|
|||
#### Distribution Directory Layout |
|||
|
|||
The RomWBW distribution is a compressed zip archive file organized in a |
|||
set of directories. Each of these directories has its own ReadMe.txt |
|||
file describing the contents in detail. In summary, these directories |
|||
are: |
|||
|
|||
| **Directory** | **Description** | |
|||
|----|----| |
|||
| **Binary** | The final output files of the build process are placed here. Most importantly, the ROM images with the file names ending in “.rom” and disk images ending in .img. | |
|||
| **Doc** | Contains various detailed documentation, both RomWBW specifically as well as the operating systems and applications. | |
|||
| **Source** | Contains the source code files used to build the software and ROM images. | |
|||
| **Tools** | Contains the programs that are used by the build process or that may be useful in setting up your system. | |
|||
|
|||
#### Building from Source |
|||
|
|||
It is also very easy to modify and build custom ROM images that fully |
|||
tailor the firmware to your specific preferences. All tools required to |
|||
build custom ROM firmware under Windows are included – no need to |
|||
install assemblers, etc. The firmware can also be built using Linux or |
|||
MacOS after confirming a few standard tools have been installed. |
|||
|
|||
## Installation & Operation |
|||
|
|||
In general, installation of RomWBW on your platform is very simple. You |
|||
just need to program your ROM with the correct ROM image from the RomWBW |
|||
distribution. Subsequently, you can write disk images on your disk |
|||
drives (IDE disk, CF Card, SD Card, etc.) which then provides even more |
|||
functionality. |
|||
|
|||
Complete instructions for installation and operation of RomWBW are found |
|||
in the [RomWBW User |
|||
Guide](https://github.com/wwarthen/RomWBW/raw/master/Doc/RomWBW%20User%20Guide.pdf). |
|||
It is also a good idea to review the [Release |
|||
Notes](https://github.com/wwarthen/RomWBW/blob/master/RELEASE_NOTES.md) |
|||
for helpful release-specific information. |
|||
|
|||
## Documentation |
|||
|
|||
There are several documents that form the core of the RomWBW |
|||
documentation: |
|||
|
|||
- [RomWBW User |
|||
Guide](https://github.com/wwarthen/RomWBW/raw/master/Doc/RomWBW%20User%20Guide.pdf) |
|||
is the main user guide for RomWBW, it covers the major topics of how |
|||
to install, manage and use RomWBW, and includes additional guidance to |
|||
the use of some of the operating systems supported by RomWBW |
|||
|
|||
- [RomWBW |
|||
Hardware](https://github.com/wwarthen/RomWBW/raw/master/Doc/RomWBW%20Hardware.pdf) |
|||
contains a description of all the hardware platforms, and devices |
|||
supported by RomWBW. |
|||
|
|||
- [RomWBW |
|||
Applications](https://github.com/wwarthen/RomWBW/raw/master/Doc/RomWBW%20Applications.pdf) |
|||
is a reference for the ROM-hosted and OS-hosted applications created |
|||
or customized to enhance the operation of RomWBW. |
|||
|
|||
- [RomWBW Disk |
|||
Catalog](https://github.com/wwarthen/RomWBW/raw/master/Doc/RomWBW%20Disk%20Catalog.pdf) |
|||
is a reference for the contents of the disk images provided with |
|||
RomWBW, with a description of many of the files on each image |
|||
|
|||
- [RomWBW System |
|||
Guide](https://github.com/wwarthen/RomWBW/raw/master/Doc/RomWBW%20System%20Guide.pdf) |
|||
discusses much of the internal design and construction of RomWBW. It |
|||
includes a reference for the RomWBW HBIOS API functions. |
|||
|
|||
An online HTML version of this documentation is hosted at |
|||
<https://wwarthen.github.io/RomWBW>. |
|||
|
|||
Each of the operating systems and ROM applications included with RomWBW |
|||
are sophisticated tools in their own right. It is not reasonable to |
|||
fully document their usage. However, you will find complete manuals in |
|||
PDF format in the Doc directory of the distribution. The intention of |
|||
this documentation is to describe the operation of RomWBW and the ways |
|||
in which it enhances the operation of the included applications and |
|||
operating systems. |
|||
|
|||
Since RomWBW is purely a software product for many different platforms, |
|||
the documentation does **not** cover hardware construction, |
|||
configuration, or troubleshooting – please see your hardware provider |
|||
for this information. |
|||

- Support for CP/NET networking using Wiznet, MT011 or Serial |
|||
- Built-in VT-100 terminal emulation support |
|||
|
|||
A dynamic disk drive letter assignment mechanism allows mapping |
|||
operating system drive letters to any available disk media. |
|||
Additionally, mass storage devices (IDE Disk, CF Card, SD Card, etc.) |
|||
support the use of multiple slices (up to 256 per device). Each slice |
|||
contains a complete CP/M filesystem and can be mapped independently to |
|||
any drive letter. This overcomes the inherent size limitations in legacy |
|||
OSes and allows up to 2GB of addressable storage on a single device, |
|||
with up to 128MB accessible at any one time. |
|||
|
|||
## Included Software |
|||
|
|||
Multiple disk images are provided in the distribution. Most disk images |
|||
contain a complete, bootable, ready-to-run implementation of a specific |
|||
operating system. A “combo” disk image contains multiple slices, each |
|||
with a full operating system implementation. If you use this disk image, |
|||
you can easily pick whichever operating system you want to boot without |
|||
changing media. |
|||
|
|||
Some of the included software: |
|||
|
|||
- Operating Systems (CP/M 2.2, ZSDOS, NZ-COM, CP/M 3, ZPM3, Z3PLUS, QPM |
|||
) |
|||
- Support for other operating systems, p-System, FreeRTOS, and FUZIX. |
|||
- Programming Tools (Z80ASM, Turbo Pascal, Forth, Cowgol) |
|||
- C Compiler’s including Aztec-C, and HI-TECH C |
|||
- Microsoft Basic Compiler, and Microsoft Fortran |
|||
- Some games such as Colossal Cave, Zork, etc |
|||
- Wordstar Word processing software |
|||
|
|||
Some of the provided software can be launched directly from the ROM |
|||
firmware itself: |
|||
|
|||
- System Monitor |
|||
- Operating Systems (CP/M 2.2, ZSDOS) |
|||
- ROM BASIC (Nascom BASIC and Tasty BASIC) |
|||
- ROM Forth |
|||
|
|||
A tool is provided that allows you to access a FAT-12/16/32 filesystem. |
|||
The FAT filesystem may be coresident on the same disk media as RomWBW |
|||
slices or on stand-alone media. This makes exchanging files with modern |
|||
OSes such as Windows, MacOS, and Linux very easy. |
|||
|
|||
## ROM Distribution |
|||
|
|||
The [RomWBW Repository](https://github.com/wwarthen/RomWBW) |
|||
(<https://github.com/wwarthen/RomWBW>) on GitHub is the official |
|||
distribution location for all project source and documentation. |
|||
|
|||
RomWBW is distributed as both source code and pre-built ROM and disk |
|||
images. |
|||
|
|||
The pre-built ROM images distributed with RomWBW are based on the |
|||
default system configurations as determined by the hardware |
|||
provider/designer. The pre-built ROM firmware images are generally |
|||
suitable for most users. |
|||
|
|||
The fully-built distribution releases are available on the [RomWBW |
|||
Releases Page](https://github.com/wwarthen/RomWBW/releases) |
|||
(<https://github.com/wwarthen/RomWBW/releases>) of the repository. |
|||
|
|||
On this page, you will normally see a Development Snapshot as well as |
|||
recent stable releases. Unless you have a specific reason, I suggest you |
|||
stick to the most recent stable release. |
|||
|
|||
The asset named RomWBW-vX.X.X-Package.zip includes all pre-built ROM and |
|||
Disk images as well as full source code. The other assets contain only |
|||
source code and do not have the pre-built ROM or disk images. |
|||
|
|||
#### Distribution Directory Layout |
|||
|
|||
The RomWBW distribution is a compressed zip archive file organized in a |
|||
set of directories. Each of these directories has its own ReadMe.txt |
|||
file describing the contents in detail. In summary, these directories |
|||
are: |
|||
|
|||
| **Directory** | **Description** | |
|||
|----|----| |
|||
| **Binary** | The final output files of the build process are placed here. Most importantly, the ROM images with the file names ending in “.rom” and disk images ending in .img. | |
|||
| **Doc** | Contains various detailed documentation, both RomWBW specifically as well as the operating systems and applications. | |
|||
| **Source** | Contains the source code files used to build the software and ROM images. | |
|||
| **Tools** | Contains the programs that are used by the build process or that may be useful in setting up your system. | |
|||
|
|||
#### Building from Source |
|||
|
|||
It is also very easy to modify and build custom ROM images that fully |
|||
tailor the firmware to your specific preferences. All tools required to |
|||
build custom ROM firmware under Windows are included – no need to |
|||
install assemblers, etc. The firmware can also be built using Linux or |
|||
MacOS after confirming a few standard tools have been installed. |
|||
|
|||
## Installation & Operation |
|||
|
|||
In general, installation of RomWBW on your platform is very simple. You |
|||
just need to program your ROM with the correct ROM image from the RomWBW |
|||
distribution. Subsequently, you can write disk images on your disk |
|||
drives (IDE disk, CF Card, SD Card, etc.) which then provides even more |
|||
functionality. |
|||
|
|||
Complete instructions for installation and operation of RomWBW are found |
|||
in the [RomWBW User |
|||
Guide](https://github.com/wwarthen/RomWBW/raw/master/Doc/RomWBW%20User%20Guide.pdf). |
|||
It is also a good idea to review the [Release |
|||
Notes](https://github.com/wwarthen/RomWBW/blob/master/RELEASE_NOTES.md) |
|||
for helpful release-specific information. |
|||
|
|||
## Documentation |
|||
|
|||
There are several documents that form the core of the RomWBW |
|||
documentation: |
|||
|
|||
- [RomWBW User |
|||
Guide](https://github.com/wwarthen/RomWBW/raw/master/Doc/RomWBW%20User%20Guide.pdf) |
|||
is the main user guide for RomWBW, it covers the major topics of how |
|||
to install, manage and use RomWBW, and includes additional guidance to |
|||
the use of some of the operating systems supported by RomWBW |
|||
|
|||
- [RomWBW |
|||
Hardware](https://github.com/wwarthen/RomWBW/raw/master/Doc/RomWBW%20Hardware.pdf) |
|||
contains a description of all the hardware platforms, and devices |
|||
supported by RomWBW. |
|||
|
|||
- [RomWBW |
|||
Applications](https://github.com/wwarthen/RomWBW/raw/master/Doc/RomWBW%20Applications.pdf) |
|||
is a reference for the ROM-hosted and OS-hosted applications created |
|||
or customized to enhance the operation of RomWBW. |
|||
|
|||
- [RomWBW Disk |
|||
Catalog](https://github.com/wwarthen/RomWBW/raw/master/Doc/RomWBW%20Disk%20Catalog.pdf) |
|||
is a reference for the contents of the disk images provided with |
|||
RomWBW, with a description of many of the files on each image |
|||
|
|||
- [RomWBW System |
|||
Guide](https://github.com/wwarthen/RomWBW/raw/master/Doc/RomWBW%20System%20Guide.pdf) |
|||
discusses much of the internal design and construction of RomWBW. It |
|||
includes a reference for the RomWBW HBIOS API functions. |
|||
|
|||
An online HTML version of this documentation is hosted at |
|||
<https://wwarthen.github.io/RomWBW>. |
|||
|
|||
Each of the operating systems and ROM applications included with RomWBW |
|||
are sophisticated tools in their own right. It is not reasonable to |
|||
fully document their usage. However, you will find complete manuals in |
|||
PDF format in the Doc directory of the distribution. The intention of |
|||
this documentation is to describe the operation of RomWBW and the ways |
|||
in which it enhances the operation of the included applications and |
|||
operating systems. |
|||
|
|||
Since RomWBW is purely a software product for many different platforms, |
|||
the documentation does **not** cover hardware construction, |
|||
configuration, or troubleshooting – please see your hardware provider |
|||
for this information. |

Overview |
|||
|
|||
RomWBW software provides a complete, commercial quality implementation |
|||
of CP/M (and work-alike) operating systems and applications for modern |
|||
Z80/180/280 retro-computing hardware systems. |
|||
|
|||
A wide variety of platforms are supported including those produced by |
|||
these developer communities: |
|||
|
|||
- RetroBrew Computers (https://www.retrobrewcomputers.org) |
|||
- RC2014 (https://rc2014.co.uk), |
|||
RC2014-Z80 (https://groups.google.com/g/rc2014-z80) |
|||
- Retro Computing (https://groups.google.com/g/retro-comp) |
|||
- Small Computer Central (https://smallcomputercentral.com/) |
|||
|
|||
A complete list of the currently supported platforms is found in RomWBW |
|||
Hardware . |
|||
|
|||
Description |
|||
|
|||
Primary Features |
|||
|
|||
By design, RomWBW isolates all of the hardware specific functions in the |
|||
ROM chip itself. The ROM provides a hardware abstraction layer such that |
|||
all of the operating systems and applications on a disk will run on any |
|||
RomWBW-based system. To put it simply, you can take a disk (or CF/SD/USB |
|||
Card) and move it between systems transparently. |
|||
|
|||
Supported hardware features of RomWBW include: |
|||
|
|||
- Z80 Family CPUs including Z80, Z180, and Z280 |
|||
- Banked memory services for several banking designs |
|||
- Disk drivers for RAM, ROM, Floppy, IDE ATA/ATAPI, CF, SD, USB, Zip, |
|||
Iomega |
|||
- Serial drivers including UART (16550-like), ASCI, ACIA, SIO |
|||
- Video drivers including TMS9918, SY6545, MOS8563, HD6445, Xosera |
|||
- Keyboard (PS/2) drivers via VT8242 or PPI interfaces |
|||
- Real time clock drivers including DS1302, BQ4845 |
|||
- Support for CP/NET networking using Wiznet, MT011 or Serial |
|||
- Built-in VT-100 terminal emulation support |
|||
|
|||
A dynamic disk drive letter assignment mechanism allows mapping |
|||
operating system drive letters to any available disk media. |
|||
Additionally, mass storage devices (IDE Disk, CF Card, SD Card, etc.) |
|||
support the use of multiple slices (up to 256 per device). Each slice |
|||
contains a complete CP/M filesystem and can be mapped independently to |
|||
any drive letter. This overcomes the inherent size limitations in legacy |
|||
OSes and allows up to 2GB of addressable storage on a single device, |
|||
with up to 128MB accessible at any one time. |
|||
|
|||
Included Software |
|||
|
|||
Multiple disk images are provided in the distribution. Most disk images |
|||
contain a complete, bootable, ready-to-run implementation of a specific |
|||
operating system. A “combo” disk image contains multiple slices, each |
|||
with a full operating system implementation. If you use this disk image, |
|||
you can easily pick whichever operating system you want to boot without |
|||
changing media. |
|||
|
|||
Some of the included software: |
|||
|
|||
- Operating Systems (CP/M 2.2, ZSDOS, NZ-COM, CP/M 3, ZPM3, Z3PLUS, |
|||
QPM ) |
|||
- Support for other operating systems, p-System, FreeRTOS, and FUZIX. |
|||
- Programming Tools (Z80ASM, Turbo Pascal, Forth, Cowgol) |
|||
- C Compiler’s including Aztec-C, and HI-TECH C |
|||
- Microsoft Basic Compiler, and Microsoft Fortran |
|||
- Some games such as Colossal Cave, Zork, etc |
|||
- Wordstar Word processing software |
|||
|
|||
Some of the provided software can be launched directly from the ROM |
|||
firmware itself: |
|||
|
|||
- System Monitor |
|||
- Operating Systems (CP/M 2.2, ZSDOS) |
|||
- ROM BASIC (Nascom BASIC and Tasty BASIC) |
|||
- ROM Forth |
|||
|
|||
A tool is provided that allows you to access a FAT-12/16/32 filesystem. |
|||
The FAT filesystem may be coresident on the same disk media as RomWBW |
|||
slices or on stand-alone media. This makes exchanging files with modern |
|||
OSes such as Windows, MacOS, and Linux very easy. |
|||
|
|||
ROM Distribution |
|||
|
|||
The RomWBW Repository (https://github.com/wwarthen/RomWBW) on GitHub is |
|||
the official distribution location for all project source and |
|||
documentation. |
|||
|
|||
RomWBW is distributed as both source code and pre-built ROM and disk |
|||
images. |
|||
|
|||
The pre-built ROM images distributed with RomWBW are based on the |
|||
default system configurations as determined by the hardware |
|||
provider/designer. The pre-built ROM firmware images are generally |
|||
suitable for most users. |
|||
|
|||
The fully-built distribution releases are available on the RomWBW |
|||
Releases Page (https://github.com/wwarthen/RomWBW/releases) of the |
|||
repository. |
|||
|
|||
On this page, you will normally see a Development Snapshot as well as |
|||
recent stable releases. Unless you have a specific reason, I suggest you |
|||
stick to the most recent stable release. |
|||
|
|||
The asset named RomWBW-vX.X.X-Package.zip includes all pre-built ROM and |
|||
Disk images as well as full source code. The other assets contain only |
|||
source code and do not have the pre-built ROM or disk images. |
|||
|
|||
Distribution Directory Layout |
|||
|
|||
The RomWBW distribution is a compressed zip archive file organized in a |
|||
set of directories. Each of these directories has its own ReadMe.txt |
|||
file describing the contents in detail. In summary, these directories |
|||
are: |

Building from Source |
|||
|
|||
It is also very easy to modify and build custom ROM images that fully |
|||
tailor the firmware to your specific preferences. All tools required to |
|||
build custom ROM firmware under Windows are included – no need to |
|||
install assemblers, etc. The firmware can also be built using Linux or |
|||
MacOS after confirming a few standard tools have been installed. |
|||
|
|||
Installation & Operation |
|||
|
|||
In general, installation of RomWBW on your platform is very simple. You |
|||
just need to program your ROM with the correct ROM image from the RomWBW |
|||
distribution. Subsequently, you can write disk images on your disk |
|||
drives (IDE disk, CF Card, SD Card, etc.) which then provides even more |
|||
functionality. |
|||
|
|||
Complete instructions for installation and operation of RomWBW are found |
|||
in the RomWBW User Guide. It is also a good idea to review the Release |
|||
Notes for helpful release-specific information. |
|||
|
|||
Documentation |
|||
|
|||
There are several documents that form the core of the RomWBW |
|||
documentation: |
|||
|
|||
- RomWBW User Guide is the main user guide for RomWBW, it covers the |
|||
major topics of how to install, manage and use RomWBW, and includes |
|||
additional guidance to the use of some of the operating systems |
|||
supported by RomWBW |
|||
|
|||
- RomWBW Hardware contains a description of all the hardware |
|||
platforms, and devices supported by RomWBW. |
|||
|
|||
- RomWBW Applications is a reference for the ROM-hosted and OS-hosted |
|||
applications created or customized to enhance the operation of |
|||
RomWBW. |
|||
|
|||
- RomWBW Disk Catalog is a reference for the contents of the disk |
|||
images provided with RomWBW, with a description of many of the files |
|||
on each image |
|||
|
|||
- RomWBW System Guide discusses much of the internal design and |
|||
construction of RomWBW. It includes a reference for the RomWBW HBIOS |
|||
API functions. |
|||
|
|||
An online HTML version of this documentation is hosted at |
|||
https://wwarthen.github.io/RomWBW. |
|||
|
|||
Each of the operating systems and ROM applications included with RomWBW |
|||
are sophisticated tools in their own right. It is not reasonable to |
|||
fully document their usage. However, you will find complete manuals in |
|||
PDF format in the Doc directory of the distribution. The intention of |
|||
this documentation is to describe the operation of RomWBW and the ways |
|||
in which it enhances the operation of the included applications and |
|||
operating systems. |
|||
|
|||
Since RomWBW is purely a software product for many different platforms, |
|||
the documentation does not cover hardware construction, configuration, |
|||
or troubleshooting – please see your hardware provider for this |
|||
information. |

OVERVIEW |
|||
|
|||
|
|||
RomWBW software provides a complete, commercial quality implementation |
|||
of CP/M (and work-alike) operating systems and applications for modern |
|||
Z80/180/280 retro-computing hardware systems. |
|||
|
|||
A wide variety of platforms are supported including those produced by |
|||
these developer communities: |
|||
|
|||
- RetroBrew Computers (https://www.retrobrewcomputers.org) |
|||
- RC2014 (https://rc2014.co.uk), |
|||
RC2014-Z80 (https://groups.google.com/g/rc2014-z80) |
|||
- Retro Computing (https://groups.google.com/g/retro-comp) |
|||
- Small Computer Central (https://smallcomputercentral.com/) |
|||
|
|||
A complete list of the currently supported platforms is found in RomWBW |
|||
Hardware . |
|||
|
|||
|
|||
|
|||
DESCRIPTION |
|||
|
|||
|
|||
Primary Features |
|||
|
|||
By design, RomWBW isolates all of the hardware specific functions in the |
|||
ROM chip itself. The ROM provides a hardware abstraction layer such that |
|||
all of the operating systems and applications on a disk will run on any |
|||
RomWBW-based system. To put it simply, you can take a disk (or CF/SD/USB |
|||
Card) and move it between systems transparently. |
|||
|
|||
Supported hardware features of RomWBW include: |
|||
|
|||
- Z80 Family CPUs including Z80, Z180, and Z280 |
|||
- Banked memory services for several banking designs |
|||
- Disk drivers for RAM, ROM, Floppy, IDE ATA/ATAPI, CF, SD, USB, Zip, |
|||
Iomega |
|||
- Serial drivers including UART (16550-like), ASCI, ACIA, SIO |
|||
- Video drivers including TMS9918, SY6545, MOS8563, HD6445, Xosera |
|||
- Keyboard (PS/2) drivers via VT8242 or PPI interfaces |
|||
- Real time clock drivers including DS1302, BQ4845 |
|||
- Support for CP/NET networking using Wiznet, MT011 or Serial |
|||
- Built-in VT-100 terminal emulation support |
|||
|
|||
A dynamic disk drive letter assignment mechanism allows mapping |
|||
operating system drive letters to any available disk media. |
|||
Additionally, mass storage devices (IDE Disk, CF Card, SD Card, etc.) |
|||
support the use of multiple slices (up to 256 per device). Each slice |
|||
contains a complete CP/M filesystem and can be mapped independently to |
|||
any drive letter. This overcomes the inherent size limitations in legacy |
|||
OSes and allows up to 2GB of addressable storage on a single device, |
|||
with up to 128MB accessible at any one time. |
|||
|
|||
|
|||
Included Software |
|||
|
|||
Multiple disk images are provided in the distribution. Most disk images |
|||
contain a complete, bootable, ready-to-run implementation of a specific |
|||
operating system. A “combo” disk image contains multiple slices, each |
|||
with a full operating system implementation. If you use this disk image, |
|||
you can easily pick whichever operating system you want to boot without |
|||
changing media. |
|||
|
|||
Some of the included software: |
|||
|
|||
- Operating Systems (CP/M 2.2, ZSDOS, NZ-COM, CP/M 3, ZPM3, Z3PLUS, QPM |
|||
) |
|||
- Support for other operating systems, p-System, FreeRTOS, and FUZIX. |
|||
- Programming Tools (Z80ASM, Turbo Pascal, Forth, Cowgol) |
|||
- C Compiler’s including Aztec-C, and HI-TECH C |
|||
- Microsoft Basic Compiler, and Microsoft Fortran |
|||
- Some games such as Colossal Cave, Zork, etc |
|||
- Wordstar Word processing software |
|||
|
|||
Some of the provided software can be launched directly from the ROM |
|||
firmware itself: |
|||
|
|||
- System Monitor |
|||
- Operating Systems (CP/M 2.2, ZSDOS) |
|||
- ROM BASIC (Nascom BASIC and Tasty BASIC) |
|||
- ROM Forth |
|||
|
|||
A tool is provided that allows you to access a FAT-12/16/32 filesystem. |
|||
The FAT filesystem may be coresident on the same disk media as RomWBW |
|||
slices or on stand-alone media. This makes exchanging files with modern |
|||
OSes such as Windows, MacOS, and Linux very easy. |
|||
|
|||
|
|||
ROM Distribution |
|||
|
|||
The RomWBW Repository (https://github.com/wwarthen/RomWBW) on GitHub is |
|||
the official distribution location for all project source and |
|||
documentation. |
|||
|
|||
RomWBW is distributed as both source code and pre-built ROM and disk |
|||
images. |
|||
|
|||
The pre-built ROM images distributed with RomWBW are based on the |
|||
default system configurations as determined by the hardware |
|||
provider/designer. The pre-built ROM firmware images are generally |
|||
suitable for most users. |
|||
|
|||
The fully-built distribution releases are available on the RomWBW |
|||
Releases Page (https://github.com/wwarthen/RomWBW/releases) of the |
|||
repository. |
|||
|
|||
On this page, you will normally see a Development Snapshot as well as |
|||
recent stable releases. Unless you have a specific reason, I suggest you |
|||
stick to the most recent stable release. |
|||
|
|||
The asset named RomWBW-vX.X.X-Package.zip includes all pre-built ROM and |
|||
Disk images as well as full source code. The other assets contain only |
|||
source code and do not have the pre-built ROM or disk images. |
|||
|
|||
Distribution Directory Layout |
|||
|
|||
The RomWBW distribution is a compressed zip archive file organized in a |
|||
set of directories. Each of these directories has its own ReadMe.txt |
|||
file describing the contents in detail. In summary, these directories |
|||
are: |
|||
|
|||
------------------------------------------------------------------------- |
|||
DIRECTORY DESCRIPTION |
|||
----------- ------------------------------------------------------------- |
|||
BINARY The final output files of the build process are placed here. |
|||
Most importantly, the ROM images with the file names ending |
|||
in “.rom” and disk images ending in .img. |
|||
|
|||
DOC Contains various detailed documentation, both RomWBW |
|||
specifically as well as the operating systems and |
|||
applications. |
|||
|
|||
SOURCE Contains the source code files used to build the software and |
|||
ROM images. |
|||
|
|||
TOOLS Contains the programs that are used by the build process or |
|||

|||
------------------------------------------------------------------------- |
|||
|
|||
Building from Source |
|||
|
|||
It is also very easy to modify and build custom ROM images that fully |
|||
tailor the firmware to your specific preferences. All tools required to |
|||

|||
install assemblers, etc. The firmware can also be built using Linux or |

In general, installation of RomWBW on your platform is very simple. You |
|||
just need to program your ROM with the correct ROM image from the RomWBW |
