retrocomputing

Unlike traditional VME systems, the ART Bus is intended for retro-computing, processor development and hardware experimentation rather than industrial automation.

Escargot NxServer is an OSCAR-based modernization of the base NINA server which uses protocol gateways to also provide access to clients supporting TOC, WebAPI, P3, and MSNP -- all of which are in active development.

A public collection of useful retrocomputing scripts, configs, demos, and notes related to early Z80 non-home-computers. One category is emulation of old Z80 (or 8080) CP/M systems like the Altair 8800 and similar. Another category is modern recreations using S100, RC2014, ECB and other buses. I'd add a special exception for not Z80 but close enough like my CPM-68K system or my old Heathkit H8 which technically had an 8080 CPU board, as shipped.

ShellDOS (or simply shDOS) is a retro DOS Command Shell with modern features like Linux and others.

8-Bit Wonders is a flexible and easy to use Commodore 8-bit emulator with builtin games. You can play both old and new pixel games in the style of the 80s while retaining all the advantages of your modern Android device (of course, other programs besides games also work). 8-Bit-Wonders is based on VICE and adds an androidish user interface.

A public collection of useful retrocomputing scripts, configs, demos, and notes related to Pre-Windows era PC retrocomputing. MSDOS 3.3, CP/M, the kind of stuff you ran before Linux even existed in the 80s.

This is a project aimed at documenting as many pieces of hardware as possible, built on a Symfony HTML framework.

A rudimentary firmware for replicas of the Acorn Archimedes, also includes a BBC BASIC compatible interpreter as well.

This is an emulator of Elektronika UKNC (Электроника УК-НЦ/МС 0511) soviet personal microcomputer. Designed to be portable, it's using SDL3. Can be built for Windows, Linux and probably other unix flavours.

Tiny Pascal compiler source from the Byte Book of Pascal along with side implementations for a couple of specific models.

An unpacked copy of the code libraries developed in the text Software Tools in Pascal.

Code that is, or very nearly is, Li-Chen Wang’s 8080 Tiny Basic. This is where it all really started.

An old Z80 Forth implementation. See a better version on GitHub.
