Update:

The keyboard I found first is in good condition, but rattles slightly,
as if something the size of a small screw or motherboard jumper is
loose inside it.

I was wondering where I might find a screwdriver bit with a female
hexagonal tip, to open the keyboard, when I found two more IBM PS/2
keyboards; they don't rattle, but do have twenty years of accumulated
fluff and grime on them.

All this is still pending the results of a "press every key" test, but
if you want the one that is in slightly better condition, I can clean
it by:

1. Scraping off the fluff with toothpicks.
2. Wiping away the surface grime with Flash wet-wipes.
3. Washing the removable key outers in soapy water.
