Found this last night USB to PS2

A 2040/pico should be able to do this too.

I've seen a photo of it and I refuse to solder it. lol

Well, an RP2040 might be able to do it, but you only have one USB port. It probably needs some C programming or, maybe, python might have some libraries that might help.

from a forum posting almost a year ago:

"... the CH375/CH376 also looks like an option, available on a small PCB for around $5 on ebay:
https://www.ebay.com/itm/164195409955
https://www.ebay.com/itm/165027473834
(note: the CH376 may be an updated version of the CH375, and so a better choice)
while the main target is reading USB flash drives, it appears to also produce results from USB keyboards and mouses. it can connect directly to a TTL serial port, and requires to be sent commands and returns packets of data containing keypress information - NOT ASCII codes; some interpretation is required.

Too bad you are all so far away.

There are plenty PS2 keyboards available here in the Netherlands at this company:

Logitech USB keyboard

And trust me: they have plenty in stock.

Call those "keyboards"?
This is a keyboard (schematic). More info.
None of that silly serial malarky. And keys that don't wear out because they have no contacts... :)
