Down a rabbit-hole

Not really related to Unix, but emulation. The 86Box emulator (plus roms) contains a good ps/2 and ps/1 emulator and I've been doing some reading on what different specs were etc.

I wanted to put some links here for future refernce:

Chart of PS/1 specs from https://www.old-computers.com/museum/doc.asp?c=1274

There were later many different PS/1 Models released.
Here is a quite complete list of them with main technical differences:
