If I'm not mistaken, ADB-to-USB adapters are available. They're intended for hooking ADB keyboards and mice to newer Macs, but as long as it shows up to the computer as an HID and not as something weird, it should work with anything that'd take a USB keyboard.
Last spring I was in a shop that had a couple of ADB keyboards connected to PCs using the Griffin iMate ADB to USB adapters. Seemed to work well as far as I could tell.
