PicoMicroMac v2

[Ron's Computer Videos]

Based on community feedback, I've updated the design on the PicoMicroMac (breakout board for Evan's wonderful PicoMac 128K emulator - based on uMac) to integrate SD card for folks who don't want to solder. Pop on a Pi Pico H, or buy them preflashed from JCM-1. Add a USB-OTG hub and connect USB keyboard and mouse and you're off to the races!

I purchased one of @Ron's Computer Videos boards at VCFMW 20 from Joe's Computer Museum, inside one of Joe's 3D printed cases. It is really cute.

Here are my notes:
1. I had to enlarge the hole in the 3D case for the mouse input. A lot of these 'on-the-go' cables have fat connectors.

2. One brand of on-the-go cable did not like when my optical mouse would go to sleep. Switched to another cable and it works fine.

3. I downloaded the umac0.img drive from your website, Ron, and installed it on a 16GB SD card formatted with FAT32. Worked great. My first attempt was to use a blank .img file, because I didn't realize that it needed a System file as the ROM drive won't show up in addition to the external drive.

4. It helped me catch a bug in my code, as I thought this would be a Mac 128 with original 64K ROMs. Digging deeper into github, it is clearly documented as a Mac 128Ke (so to speak). It has modified v3 MacPlus ROMs.

5. My code detects it as emulated on Basilisk. I suppose this is because the disk emulator code is from that project. Is evansm7 on this forum? I'd like to ask how to differentiate the pico-mac from Basilisk.

In any case, a really cool and fun project!
