I have several PC/104 systems and sound would be a big upgrade. Doc no problem, let me clean up the …

https://imgur.com/69t0wnV.jpeg These are awesome! I managed to build a WeeCee, and I’m using a MiSTer MT32-PI connected externally, with its DAC audio routed back into the sound chip. It works great, but I really love the idea of using the PicoGUS instead of the Crystal chip—such a brilliant …

For everyone who wanted to use PicoGUS with industrial SBC's - I made PicoGUS v2.0 PCB variant for PC/104 bus (which is same as ISA bus just in other physical form). All source files and files required to manufacture PCB are available at this link: https://github.com/UzixLS/picogus104 . Small demo …

@snipe3687 any chance of fitting an FC1307 chip on there? it looks like you've run out of space though. So the problem I’ve had with that isn’t space necessarily but availability of the IC. I can’t seem to find any stock of the chip by itself. I suppose I could take one apart and salvage the IC but …

check the header on the bottom of the SOM. those pins can get broken if you're not careful but I wouldn't expect that to not work at all. I had some pins on one of mine that I missed soldering but that made the screen show up without blue instead of no screen altogether. is this the only WeeCee …

Have you made your KiCad weeCee project files available or would you mind sharing them? It doesn't look like it got pulled into rasteri's github repo. I'm planning a build based around the SOM304RD module, and I'd prefer KiCad instead of Altium. Integrated HIDman would also be nice, if you've done …

What features would you like? I'd certainly like to add a builtin HIDman - having to use PS/2 peripherals on the weecee is kinda a pain I could probably add that into the design I did for my KiCad interpretation. I’ve added it to just about every other project I’ve worked on recently ;) Have you …

@snipe3687 didn't have much time to work on this. I did manage to rewrite part of the FPGA code, and I'm now using IDDR and FIFOs, so the timings coming out of the FPGA should be pretty much perfect. For the LVDS version, 512x384 up to 1920x1080p properly works. (except 960x720, 1280x720, 1360x768, …

honest question, why are these cards so sensitive?

I've since switched to just having the chips soldered on by …
