  1. Well, not the last thing. Forgot I hadn't made the backup battery pack for the Multi-Unit 64 that fastens to the bottom. It has another ROM "capsule" and 64K of RAM disk storage.

    Welded the pack (it's 4AA NiCd), then realized the rusty switch to enable it was totally seized. Removed it and best I had on hand was a tiny slider switch with six pins. Fortunately, three pins aligned if bent 90, so I hacked it.

    Flipped on, tested RAM ICs and got 5v VDD/GND. Done!

  2. What have two Amigas, a custom made null modem cable, Serial communications and AMOS got in common?


    This latest video from me of course. 😁

    Yes, I’m getting Amigas talking to each other in this one.

  3. @wyatt If it's anything like MS-DOS 6.22 on an IBM PS/ValuePoint that I've used, the pause after the first `dir` on a drive comes from reading the whole FAT to estimate used and unused disk space for the footer of `dir` output. It's like running `ls -l && df .` on GNU/Linux. Subsequent `dir` runs don't pause because the FAT is cached. If you run `dir` for the first time after boot with a format that does not display free space, such as `dir /b`, does that also produce a 1-second pause?

  4. If you're interested in hobbyist #IBM i (née System i / AS/400) hardware and installation, this is a great watch: youtu.be/mUwJk81YatA

    Check out the rest of clabretro's channel too - lots of #retrocomputing content, focussing on 90s/early 2000 enterprise hardware and software.

  5. En fouillant l'histoire de la micro-informatique française, on tombe parfois sur de sacrées machines.
    Voici le U183, construit par Saint-Ignan Électronique à Saint-Gaudens autour de l'architecture Tavernier

    Bref, en Haute-Garonne en 1983, on ne faisait pas que du cassoulet.
    On faisait aussi du bank switching.

  6. ZenZX v0.6.7 is out

    — a preview release on the ramp-up to v1.0.

    ZenZX is a ZX Spectrum emulator in Go (48K/128K/+2/+3, now TS2068 too).

    What's new:

    • New menu system: Light, Dark, and Spectrum themes, selectable fonts
    • GUI toolkit reused from zenimate, including file dialogs
    • TS2068 support, with hi-colour mode
    • Tape loading improved: new -tapemode=turbo, more precise .tap/.tzx decoding via zentools
    • ULA memory contention implemented
    • Joystick (Kempston, Sinclair) and mouse (Kempston, AMX) support

    Builds for Windows, Mac, FreeBSD, and Linux available. This is an interim release, no guarantees whatsoever, BUGS ARE EXPECTED and feedback is very, very, welcome!

    More to come before v1.0.

  8. ... and MZ-700 "works" now as well. Time to unpick the diagnostics and do some mild refactoring of the cassette read and write routines. They are a mess and very fragile even without diagnostics, so a full refactor will need performing before I think about extending the code to cope with sequential and random data files for disks. A job for the winter months. #PicoMZ #RetroComputing

  9. Is there a project to bring back the NewtonOS to any kind of smartphone? It’s written entirely in C++, so it shouldn’t be impossible. My Newton is getting old lately.

  10. On continue dans la fouille des archives #retrocomputing avec ce manuel pour #Apple ][ de 1979. Il explique comment installer la carte d’extension et y brancher 1 ou 2 lecteurs de disquettes et ensuite comment les utiliser.

    Il est toujours fascinant de se rappeler à quel point les machines Apple étaient extensibles et ouvertes à l’époque (capot fermant par velcro, schéma électriques et électroniques fournis d’office, desassembleur intégré, etc.

  11. Postscript-Interpreter: Ghostscript 10.07.1

    Oliver Brunner hat die aktuelle Version des Postscript-Interpreters Ghostscript auf AmigaOS portiert. Da Ghostscript sehr speicherhungrig sei, empfiehlt der Entwickler beim Start des Kommandozeilen-Tools mindestens 20 Megabyte RAM frei zu haben.
