PicoMac on a Pi Pico 2. - BigPete - 03-03-2026

The PicoMac project has been around for a few years. It's based on an RP2040 and emulates a 128k mac. https://github.com/evansm7/pico-mac

I'm considering trying to get that running on a RP2350B (the one with the extra IO) and seeing if it could emulate a later 68k mac, or do some fun stuff with the extra I/O. (Serial Port? AppleTalk? USB floppy drive? BlueSCSI? i dunno)

Going to buy one of these next time I get paid: https://lectronz.com/products/rp2350-stamp-xl

Will also pick up some PSRAM. 2MB should be enough: https://www.mouser.com/ProductDetail/AP-Memory/APS1604M-3SQR-SN?qs=IS%2B4QmGtzzpULD7HVv5Qww==

I'm sure others have done similar work already, so I'll be doing some recon first. I know that the PicoMicroMac is a thing that adds SD card support and a VGA output: https://github.com/TechByAndroda/pico-mac

In the mean time, I have a standard 2350 pi pico 2 so I'm going to start by getting the project running there.

actually, putting a pin in this. While looking for some components I stumbled across my stash of NEC V20's that I haven't tested yet. So I'm going to see if I can get any life out of these.

Still sounds like a fun project though.
