Connecting old retro keyboards to USB with a cheap Raspberry PI PICO for MiSTerFPGA cores.

This video was made possible with the support of PCBWAY.....https://www.pcbway.com/ For a while I wanted to use an actual old keyboard with my MiSTer and design an addon for my wedge case so I decided to look at KMK firmware that a lot of people use for custom mechanical keyboard. KMK and Circuit python was very easy to use and just had to change the examples to work with the small selection of keyboards I had to try. While I was working on this I also found the BBC and Amiga 600 projects , but I was not able to borrow an A600 keyboard for the video. My scripts used. https://github.com/midicdj1000/RETRO-PICO-KMK-Keyboards BBC PICO keyboard project https://alexparsons.co.uk/connecting-a-bbc-micro-keyboard-to-a-raspberry-pico/ https://github.com/ajparsons/bbc-micro-keyboard Amiga 600 PICO Keyboard https://github.com/thinghacker/Amiga600KeyboardUSBAdapter links to pcbway shared files https://circuitpython.org/ https://github.com/KMKfw/kmk_firmware Noels Amstrad CPC diagnostics http
