Hi,
Some info about ADB to PS/2 conversion, i.e. using an ADB keyboard with a PS/2 port on a PC...
As far as I know, there was never a commercial product to do that alone. You could daisy-chain e.g. a Griffin iMate ADB-to-USB converter and a USB-to-PS/2 converter, but that isn't perfect (key rollover limitation).
However, there were some multi-platform KVM switches that supported use of Mac ADB keyboards & mice. Using one of those you can connect ADB keyboards to a PS/2 PC. Way too bulky if you don't actually need the KVM function, but a good solution if you do. Some units also allow the use of Sun workstation keyboards.
Another option I just discovered is shown at http://m0115.web.fc2.com/. You might be better off reading the Google Japanese-to-English translation here (http://translate.google.com/translate?u=http%3A%2F%2Fm0115.web.fc2.com%2F&langpair=ja%7Cen&hl=en&ie=UTF8).
That shows translators for ADB keyboards, early Mac non-ADB keyboards, and some kind of Fujitsu word processor keyboards. It also has key scan code diagrams which might be useful to someone making their own.
