I recently bought USB drives: - smallish capacity 16GB (not those crazy "1 TB for £20" obvious scams) - known brand (Verbatim) - from "official store" on Amazon - came in official looking packaging I originally intended them for Gotek/Flash Floppy use, but I needed to reinstall Windows on a...

They are in rg_pal.zip attached to the message, have a look at the pld files. They are written for WinCUPL.

The script pretty much just identifies the files and gives them canonical names.

Ok, this is the new revision I'm going to order. Updated for KiCad 10, and I replaced those DIP resistor arrays with plain resistors. I didn't want to redo the whole layout, so the footprints are a bit short - but these things will most likely disappear in a cabinet where nobody is going to...

It certainly has been a while. Sigh. At the moment I have mostly the weekend, and a ton of other things to take care off. I'll need to check my notes and include a new revision in my next JLCPCB order.

Now you just need to move them to the PCB, so several roms can share a level shifter, and a microcontroller for in-circuit programming.

Started to use Fusion360, seems to work well, and it isn't as easy as in FreeCad to mess up your project. Though I haven't tried 1.0, yet.

I managed to program a device with urjtag+picoDirtyJtag. I had to remove lots of delays from the svf file to get it to complete without errors, it still printed a lot of messages, but the device worked in the end. No idea if the problem is in urjtag or dirtyjtag. I see this as cheap option to...

I got Frog Feast to run, but not the sprites: https://www.arcade-projects.com/threads/igs-pgm-frog-feast-on-real-hardware.17632/ Also some quick scrolling test: https://www.arcade-projects.com/threads/pgm-mvs-homebrew.24335/ iq_132 has done some good research in this area, but so far I didn't...

I would check if those emulators already support this. If you run this from PC style hardware than you should be able to connect both scanner and printer to a small usb hub.

Some info here, so should be feasible: https://www.arcade-projects.com/threads/naomi-2-chihiro-triforce-card-reader-emulator-initial-d3-wmmt-mario-kart-f-zero-ax.814/ I think most scanners and receipt printers nowadays go over USB, so a pi-zero should be more than enough.

Unfortunately I can't recommend the Quartus -> pof -> jed pipeline. I had it twice now where I got non-working chips: Once with a Verilog project for a someone, which was split into a few modules. This produced a chip where not all features worked correctly. Mysteriously these features worked...

Apparently they use a variation of tracker files, which someone extracted at some point. They actually play back as stereo, but that seems to be because tracker files without L/R balance information use a default channel to Left/Right mapping.

Capacitor arrays? https://www.digikey.de/short/7t9r279r You could always ask him, I guess: https://bsky.app/profile/cosam-the-great.bsky.social
