USB keyboard to PS/2 port

[Panther]

I came across this project today that looks like something a lot of retro computing people can use:

https://github.com/rasteri/HIDman

 

It's a converter to use USB keyboards and mice to connect to systems with PS/2 ports.  It's currently under development, but the author says it's quite functional.

I also found this project doing similar using a Raspberry Pi Pico, but I think I'll try out HIDman.

Nice little microcontroller. It has spi too.
 

I guess you need a TKII, AKI or Pokeymax 3/4 to provide the PS2. Perhaps it has enough Gpio to directly talk to pokey k0-5 and kr1/2 lines? Have to check the datasheet… (edit: seems to have plenty and 5v tolerant)

I used to program 8051 MCUs in the 90s.  Siemens 80515 chips to be precise, in assembly.  These WCH chips are so much fancier, and faster.

I used one of it's cousins (CH554) to add a mouse as a rollerball controller to THIS. There are links to the original source code and hex file. It was an adaption of a USB to Atari quadrature mouse device. In fact since it was intended for the Atari originally, it could still serve that purpose if someone wishes to make a board or two (gerbers are on the author's Github page).
