# Overview |
|
||||
|
|
||||
RomWBW software provides a complete, commercial quality implementation |
|
||||
of CP/M (and workalike) 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) |
|
||||
(<https://www.retrobrewcomputers.org>) |
|
||||
- [RC2014](https://rc2014.co.uk) (<https://rc2014.co.uk>), |
|
||||
[RC2014-Z80](https://groups.google.com/g/rc2014-z80) |
|
||||
(<https://groups.google.com/g/rc2014-z80>) |
|
||||
- [Retro Computing](https://groups.google.com/g/retro-comp) |
|
||||
(<https://groups.google.com/g/retro-comp>) |
|
||||
- [Small Computer Central](https://smallcomputercentral.com/) |
|
||||
(<https://smallcomputercentral.com/>) |
|
||||
|
|
||||
A complete list of the currently supported platforms is found in the |
|
||||
\[Installation\] section. |
|
||||
|
|
||||
General features 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 |
|
||||
- Keyboard (PS/2) drivers via VT8242 or PPI interfaces |
|
||||
- Real time clock drivers including DS1302, BQ4845 |
|
||||
- OSes: CP/M 2.2, ZSDOS, CP/M 3, NZ-COM, ZPM3, QPM, p-System, and |
|
||||
FreeRTOS |
|
||||
- Built-in VT-100 terminal emulation support |
|
||||
|
|
||||
RomWBW is distributed as both source code and pre-built ROM and disk |
|
||||
images. 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 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 accessible storage on a single device. |
|
||||
|
|
||||
The pre-built ROM firmware images are generally suitable for most users. |
|
||||
However, 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. |
|
||||
|
|
||||
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. |
|
||||
|
|
||||
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. |
|
||||
|
|
||||
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. |
|
||||

# Acquiring RomWBW |
|
||||
|
|
||||
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. 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. Expand the “Assets” drop-down |
|
||||
for the release you want to download, then select the asset named |
|
||||
RomWBW-vX.X.X-Package.zip. The Package asset 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. |
|
||||
|
|
||||
All source code and distributions are maintained on GitHub. Code |
|
||||
contributions are very welcome. |
|
||||
|
|
||||
# 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. |

# Acquiring RomWBW |
||||
|
|
||||
|
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. 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. |
||||
|
|
||||
|
All source code and distributions are maintained on GitHub. Code |
||||
|
contributions are very welcome. |

|
||||
|
# 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. |

OVERVIEW |
|
||||
|
|
||||
|
|
||||
RomWBW software provides a complete, commercial quality implementation |
|
||||
of CP/M (and workalike) 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 the |
|
||||
[Installation] section. |
|
||||
|
|
||||
General features 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 |
|
||||
- Keyboard (PS/2) drivers via VT8242 or PPI interfaces |
|
||||
- Real time clock drivers including DS1302, BQ4845 |
|
||||
- OSes: CP/M 2.2, ZSDOS, CP/M 3, NZ-COM, ZPM3, QPM, p-System, and |
|
||||
FreeRTOS |
|
||||
- Built-in VT-100 terminal emulation support |
|
||||
|
|
||||
RomWBW is distributed as both source code and pre-built ROM and disk |
|
||||
images. 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 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 accessible storage on a single device. |
|
||||
|
|
||||
The pre-built ROM firmware images are generally suitable for most users. |
|
||||
However, 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. |
|
||||
|
|
||||
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. |
|
||||
|
|
||||
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. |
|
||||
|
|
||||
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. |

ACQUIRING ROMWBW |
|
||||
|
|
||||
|
|
||||
The RomWBW Repository (https://github.com/wwarthen/RomWBW) on GitHub is |
|
||||
the official distribution location for all project source and |
|
||||
documentation. 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. Expand |
|
||||
the “Assets” drop-down for the release you want to download, then select |
|
||||
the asset named RomWBW-vX.X.X-Package.zip. The Package asset 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. |
|
||||
|
|
||||
All source code and distributions are maintained on GitHub. Code |
|

|
OVERVIEW |
||||
|
|
||||
|
|
||||
|
RomWBW software provides a complete, commercial quality implementation |
||||
|
of CP/M (and workalike) 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 the |
||||
|
[Installation] section. |
||||
|
|
||||
|
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 |
||||
|
- Keyboard (PS/2) drivers via VT8242 or PPI interfaces |
||||
|
- Real time clock drivers including DS1302, BQ4845 |
||||
|
- Built-in VT-100 terminal emulation support |
||||
|
|
||||
|
RomWBW is distributed as both source code and pre-built ROM and disk |
||||
|
images. 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 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 accessible storage on a single device, with |
||||
|
up to 128MB accessible at any one time. |
||||
|
|
||||
|
The pre-built ROM firmware images are generally suitable for most users. |
||||
|
However, 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. |
||||
|
|
||||
|
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. |
||||
|
|
||||
|
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. |
||||
|
|
||||
|
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. |
||||
|

|
ACQUIRING ROMWBW |
||||
|
|
||||
|
|
||||
|
The RomWBW Repository (https://github.com/wwarthen/RomWBW) on GitHub is |
||||
|
the official distribution location for all project source and |
||||
|
documentation. 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. |
||||
|
|
||||
|
All source code and distributions are maintained on GitHub. Code |
||||
|
contributions are very welcome. |
||||
|
|
||||
|
|
||||
|
|
||||
|
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. |
