retrocomputing

A port of librw and re3 to the Dreamcast https://dca3.net

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

With 8-Bit-Wonders 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)

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

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.

A public collection of useful retrocomputing scripts, configs, demos, and notes related to HP retrocomputing such as the HP2100. This is intended for retro emulation, but should work on real hardware.

A public collection of useful retrocomputing scripts, configs, demos, and notes related to TRS-80 and Tandy pre-PC home computers. If it runs MSDOS (or newer) this really isn't the correct place. On the other hand, if it runs TRSDOS, LDOS, or Microware OS-9 this is definitely exactly the correct place.

Reverse engineering of 8-bit Sharp MZ-series stuff

Bluetooth gamepad support for the Commodore 64 / Atari / Amiga, etc.

A public collection of useful retrocomputing scripts, configs, demos, and notes related to Data General retrocomputing such as the Eclipse, Nova, etc. This is intended for retro emulation, but should work on real hardware.

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.

This single-script command line tool generates images that look like standard IBM 5081 punchcards with some text. The resulting design is generally NOT a valid punch card (too many holes). The resulting images try to respect the size and shape of what would be obtained with actual punchcards as closely as possible.

A public collection of useful retrocomputing scripts, configs, demos, and notes related to 70s to early 80s Motorola non-home-computer retrocomputing such as SWTPC, Gimix, etc. If it has a SS-50/SS-30 bus, it belongs here. STD BUS is cool too. This really isn't a home computer area.

A public collection of useful retrocomputing scripts, configs, demos, and notes related to Interdata retrocomputing.

A public collection of useful retrocomputing scripts, configs, demos, and notes related to Bendix, Bull, Burroughs, GE, Honeywell, Librascope, SDS, Unisys, Xerox retrocomputing on mainframes and minicomputers of the 60s, 70s, and 80s. Pretty much if it was not a IBM or DEC mainframe this is the "Other" category. This is intended for retro emulation, but should work on real hardware.

A public collection of useful retrocomputing scripts, configs, demos, and notes related to DEC retrocomputing. Hardware such as the PDP-8, PDP-10, PDP-11, the VAX Software such as RSX-11, orginal unix, Ultrix, VMS, OS-8, etc. This is intended for retro emulation, but should work on real hardware.
