I have a vintage IBM Model F which I just bought from eBay, that I am trying to connect to my new Windows Pc. I ordered a DIN to Ps/2 converter from Newegg, because I my pc has a combined ps/2 port, so I assumed it was just going to be an easy plug and go. However. My computer can’t seem to read that there is a keyboard there! It won’t work in The BIOS and it won’t even come up in device manager. Is there are driver I need to download or something? Please help!
The only Model F keyboard which can be used on a modern PC with only a passive DIN to PS/2 converter is the 84-key AT keyboard. This keyboard type can be recognised by the 'Caps Lock', 'Num Lock' and 'Scroll Lock' lights in the top right-hand corner, and the keys being separated into three blocks.
Other keyboards such as the 83-key PC/XT keyboard or the 122-key 3270 PC / terminal keyboards require to be connected through an active protocol converter (such as "Soarer's Converter") to be usable on a PC with a PS/2 port.
It's also possible to use at least some 122-key keyboards if you burn a new microcontroller with AT-compatible firmware but that's rather more invasive than using a separate converter. (I've seen this process described as 'flashing' the microcontroller, which it isn't -- the 874x is based on EPROM, not flash!)
