This is a great project. I thought of looking into it several years ago, having a 99/4a with a bad Mitsumi membrane. I'm going to get one of the boards ordered and see about finally getting that 99 working properly. Thanks for the great project.
Hi. Have you seen the latest Mac SE emulator using a Pico? Would you be able to tweak the code so that it could run on the Pico 56? It doesnt support sound yet but does support a mouse and a keyboard and I think it also might support an SD card. So your super little board could be perfect for current use and further development.
Just picked up two kits.. one for me, one for my Brother's upcoming birthday. I'm hoping to learn how to make a VDP replacement based on the Pico, since I've been using a Yamaha V9958 in my project, but it is getting more scarce and pricey.
@AppliedCryogenics Thanks. Have you seen my pico9918 project? It does just that. Currently replaces a TMS9918A, but adds 80 column mode. I plan on supporting V9938,, V9958, F18A enhancements too at some point.
@@TroySchrapel yep! It'll be interesting to see how far they can push it in the next few years. I'm hoping for at least SNES level gameplay graphics, with 2-4 tile layers.
Greg at Arcade Shopper just let me know about these! I definitely need quite a few of these. Great job man! Now we need one for the Odyssey 2 so I don't have to make one. haha
That was my first computer ever and I had a phone modem where you actually put the phone in the cradle and a cassette tape recorder as your storage medium.
My first thought was … why not include hotswap sockets so that you can replace a bad switch trivially without soldering? Answer hit me almost immediately after: Because at least with cherry switches, it's likely the reason the switches will go bad is oxidized contacts. That's going to apply just as well to the sockets as the switches, and the sockets require surface-mount soldering (and may not continue to be made if the current fad of mechanical keyboards ever dies out…)
I'd like see similar project but with some kind of bus for expandability 🙂 It isn't necessary be real 6502 bus, it can be kind of SPI with fixed protocol but possibility extend computer with some 3rd party stuff will make it awesome! May be second NES port can be used like SIO on Atari 🙂
Looks amazing. I have a zif socket thing and the pcb says Troy Schrapel. I mucked up my first one, but I have 4 more pcbs left to try :) I notice you have a bunch of roms on that huge board. I have like 10 at28c64b chips but only 2 at28c256 ones. Would be nice to be able to use them. Keep up the great stuff.
