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.

For the keyboards, my source is Electronics Goldmine
(https://www.goldmine-elec-products.com/) for the keyboards. Usually
$10 each, but go on sale every now and then for $5.
"Blue Pills" can be gotten off of ebay or aliexpress. I use a 38 kHz
TSOP4838 DIP-3 IR Receiver. For the USB version, it's mostly a matter
of soldering on the sensor to the Blue Pill and programming it.
So no custom boards or anything. I like cheap.
