Discussions on vintage and retrocomputing
Half the "problems" have been solved by retro hardware enthousiasts. Acting like it's a big deal you have to connect a mouse and keyboard to the ps/2 ports. Even back in the early 2000s this was solved with USB to ps2 dongles.
Those mostly don't work with modern keyboards, though. The protocol switch was built into the keyboard and the dongle is just passive. It's actually a bit hard to quickly find a ps/2 compatible keyboard these days.
In the 2020s we have new active USB to PS2 dongles like HIDman.
Today I learned. I never found the need to use usb over ps/2 since I use original keyboards for my old hardware
