Here's a video about the PicoMEM, another Pico-based ISA card project similar to PicoGUS, except it focuses on memory expansion and disk drive emulation. It can expand conventional memory, add EMS memory, and replace XTIDE for hard drives and Gotek for floppies. If you saw my booth at #VCFMW, I had one running there. It's not a "finished" project but can already do a lot!

@1875e69c I often find myself having "3d printer brain" where the only solution I can think of is to print something, and also find myself in the opposite mindset, where I take forever messing with random parts to make something work when I could have designed and printed something simple instead.
Here's an update on #PicoGUS:
- I sold out of the 20 "Femto" PicoGUSes I made for VCFMW in the middle of the first day. Lots of people asked if I had them after! Yay!
- Due to the interest, I decide to make another batch. I promptly ordered more parts there to make another batch. The PSRAM chips have to ship from Mouser.
- Almost two weeks later, I got a notice saying the parts order was held up due to an "export audit" and a day later it was canceled completely with a vague explanation.
