I just posted on github a little project that takes a cheap surplus (my
last ones cost $5 NOS) IBM iPoint IR keyboard and converts it to PS/2
keyboard protocol using a cheap STM32F103 "Blue Pill" and a 3-terminal
38KHz IR receiver.   I'm currently writing the USB version which will
support the "nipple mouse" as well.

The keyboards aren't bad--they're made by Silitek ca. 1992 and have a
decent feel for a rubber dome keyboard.

The point is that with modern MCUs, any IR stuff is easy-peasy.  My
little Chinese LCR tester even reads and displays IR codes.
