  6. I made a thing! For those 3-4 people in the Fediverse who tinker with #Nascom and #GeminiMicrocomputers, I present: The 80-Bus Stop - convernient and safe storage for your 8x8" expansion cards. Enjoy ;-)

  11. Here's a weird thing I found, while restoring my old #CPM computers from #GeminiMicrocomputers: while there were models available with Winchester drives (that's harddisks for you young folks), the setup was a little weird. This was the time of the #MFM and RLL harddrives, used by other systems such as the IBM 5150. Easily recognizable by having two flat ribbon cables instead of just one for each drive. RLL was a little more tightly packed with capacity, but basically the same concept - required slightly different controllers though.

    Anyway, back to the Gemini. It featured a #SASI interface, which is sort of an early version of #SCSI. Did you connect a drive directly to it? Noooo. You connected a #Xebec SCSI/MFM controller. Did that require a lot of weird SCSI commands for telling the Xebec what disk was attached? Of course. Compared to how it's done today, very backwards.

    Which meant I had zero luck with my new #zuluscsi device. zuluscsi.com/

    I've got a plan B though.

  16. Anyone up for a game of #Zork on a GM905 system from #GeminiMicrocomputers featuring a #z80 processor, 64K memory and dual #gotek floppy emulators running #FlashFloppy? Eh? 😜

  21. Is your 40+ years old #vintagecomputer suffering from ribbon cable bird's nest syndrome? Don't delay! Print my ribbon cable chassis connector housing thing today! 🙂 Also, be gentle - I'm new to #3d :-)

  26. It's done! I figured "if you're gonna build a old school vertical #gotek enclosure, why not do it with some style?". I'm aiming for that early 80s style, and I'm quite happy with the result, although the OLED sticks out a bit. It is terribly practical for navigating disk images though. What do you think?

  31. As promised: a complete deep clean of the late #70s #GeminiMicrocomputers parallel #keyboard by #Rotec. Everything disassembled, cleaned, lubed, rubber liners treated with silicone and brand new rubber feet installed. All keys are working, but some don't sit as well in their sockets as they used, so I expect the keys to stay in place if I hit someone with it! :D Also some electrical issues with scanning of the key matrix being incredibly slow - but it lives!! 🙂

    And yeah, the "DISASSEMBLE FROM PCB SIDE" sticker was added by me. Taking this apart the wrong way will end in disaster. Learned that the hard way.

    No spiders were hurt in this cleaning, although they had clearly taken up residency at some point.

  36. I'm designing a 5.25" front for the Gotek floppy emulator that will go in my #GeminiMicrocomputers. It's vertical, has a #rotaryencoder, a 1.3" OLED display and a big fat red 5mm LED. I think it's going to look sort of period correct, if you disregard the presence of the OLED.

    And yeah, this is a test run so dimensions are minimal and color is whatever was on the #Prusa #3dprinter.
