Tims Retro Corner | PIEEE-488 Prototype SD drive for the Commodore PET @TimsRetroCorner | Uploaded January 2023 | Updated October 2024, 1 hour ago.
My Christmas/New Year "maker project" is this IEEE-488 device for the Commodore PET. Thanks to my sponsor PCBWay pcbway.com Making a PCB couldn't be easier, from just $5 for 10 boards.
I enjoyed making the Pi-1541 a few weeks ago, and I decided to try making something similar for the PET. The initial prototype is sketched out on breadboard, and programmed in Python, using a Pi400.
Yes I know there are devices out there that already do something similar (SD2PET and Pet Disk Max are two that I own), but they don't quite do what I want of them to in one way or another. And yes I also know the NoDiskEmu software that drives these devices can be forked and adapted. But I'm learning Python for work, and this is a learning experience: I want to figure out my own solution. It may not even work, but I'll have fun finding out!
This is a bit of an experiment in trying something different: it's not a repair video; it's not even a tutorial as such. In the week or so that I allowed myself to work on it, I only got so far. If you'd like to see it go further, please comment below. The next stage would be to take it to a PCB, maybe make a 3d printed case, and of course, continue the software.
