The 52MB disk apparently has decided 2026 is just too much. And the Mac does not have enough memory (yet) to boot from 7.1 that’s installed on the other SCSI disk. So we have to use the floppy. But…
Here’s a real Mac Plus booting of a floppy disk, with a video converter made out of a single Raspberry Pico! 😁 Still have to improve a few bits (the Mac sends random noise that messes the auto-adjust for optimal sampling) but look at it going! #RetroApple

The second Pico you see on the video is just a dev probe, it’s not doing anything. The Pico on the right is the one sampling and generating the DVI signal. I still have to improve the 5 to 3.3V situation (it should be possible to do it with resistors only, hopefully) and a few finishing touches on the software but I couldn’t be happier! Also it’s probably time to buy an external BlueSCSI. Poor Quantum lasted more than 30 years but it has its limits. #RetroApple
