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.

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

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.

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.

Another upload of an old textbook's companion CD.

CP/M z-machine/infocom/inform game interpreter.

A backup of the cd that came with Cobol Unleashed. Visible for those who want to see the code.

A virtual device bus that, once compiled into a PDP-11 SimH simulator, allows new devices to be added to the system without re-compiling the simulator itself. New devices run as separate processes, communicating with the main simulator through shared memory and pipes.

Yksi konsoli, 30 vuotta historiaa: The Chronicles of Ultimate Retro Station on tekninen aikakone, joka kuratoi kotitietokoneiden ja pelikonsolien evoluution vuosilta 1977–2006 yhteen optimoituun konsoliin.

Reverse engineering of 8-bit Sharp MZ-series stuff

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.

A public collection of useful retrocomputing scripts, configs, demos, and notes related to 60s/70s/80s IBM Mainframe retrocomputing such as the IBM700 series, IBM1130, IBM1401, System 360 OS such as MUSIC/SP and MVT and MVS, etc. This is intended for retro emulation, but should work on real hardware if you have it.
