Part of my STFM motherboard series.

My STFM is merely a motherboard. I've added a Gotek drive emulator, a new PSU, bus pull-ups and an accelerator, but I don't have a keyboard (and therefore mouse or joystick port).

Step up FieldOfCows' Raspberry Pi Pico-based IKBD emulator. Originally intended to replace a broken external keyboard on a Mega ST, it will work just as well on a STFM, STE or Falcon. Let's see how we get on.

To program the Pico, simply hold down the BOOTSEL button and connect to your PC. Most OSs will now present you with a virtual drive. Copy the atari_ikbd.uf2 file onto this drive. The Pico will instantly reboot and unmount itself. That's it.

Video includes the track "Wakka Wakka" by Brian Teoh, who I thank very much for releasing his music into the public domain.
