# 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. |
|||
|
|||
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 |
|||
* Support for CP/NET networking using Wiznet, MT011 or Serial |
|||
* 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) |
|||
(<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 $doc_user$. 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. |
|||

# Acknowledgments |
|||
|
|||
I want to acknowledge that a great deal of the code and inspiration |
|||
for RomWBW has been provided by or derived from the work of others |
|||
in the RetroBrew Computers Community. I sincerely appreciate all of |
|||
their contributions. The list below is probably missing many names -- |
|||
please let me know if I missed you! |
|||
|
|||
* Andrew Lynch started it all when he created the N8VEM Z80 SBC |
|||
which became the first platform RomWBW supported. Some of his |
|||
original code can still be found in RomWBW. |
|||
|
|||
* Dan Werner wrote much of the code from which RomWBW was originally |
|||
derived and he has always been a great source of knowledge and |
|||
advice. |
|||
|
|||
* Douglas Goodall contributed code, time, testing, and advice in "the |
|||
early days". He created an entire suite of application programs to |
|||
enhance the use of RomWBW. Unfortunately, they have become unusable |
|||
due to internal changes within RomWBW. As of RomWBW 2.6, these |
|||
applications are no longer provided. |
|||
|
|||
* Sergey Kiselev created several hardware platforms for RomWBW |
|||

|||
SD Card driver. |
|||

* Ed Brindley contributed some of the code that supports the RCBus |
|||
platform. |
|||

which has exponentially increased RomWBW usage. Some of his kits |
|||
include RomWBW. |

* Stephen Cousins has likewise created a series of hobbyist kit |
|||
computers at Small Computer Central and is distributing RomWBW |
|||
with many of them. |
|||
|

* Alan Cox has contributed some driver code and has provided a great |
|||
deal of advice. |

compendium. |
|||
|
|||
* Martin R has provided substantial help reviewing and improving the |
|||
User Guide and Applications documents. |
|||
|
|||
* Mark Pruden has made a wide variety of contributions including: |
|||
- significant content in the Disk Catalog and User Guide |
|||
- creation of the Introduction and Hardware documents |
