While tidying up I've found a few Irman infrared

they connect via a 9 pin serial plug and then convert any consumer
remote IR signals they receive into serial.
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.
