Fairly certain my first computer used something like this for the keyboard. I did not have a mouse.
IIRC, that's electrically compatible with the smaller, more fragile PS/2 connector. The adapters are just wiring it down to the smaller connector (and maybe some impedance matching resistors?).
I did have a converter from this to a ps/2 connection when I got a newer computer.
Should also work with a USB to PS/2 so you can use it on a modern machine if you want. Some modern keyboards are still backward compatible as well. I have a USB keyboard I can use on my old Din machines using two adapters.
Only if it's an AT keyboard. XT keyboards are incompatible and require active conversions. They use the same port.
