I know the Dell AT101 and ALPS MCL-101 have the same switches, but the ALPS has a giant enter, longer spacebar, DIN5 adapter, no windows keys, and the Dell may or may not have a steel backplate, so I'm specifically looking for another ALPS MCL-101 :-).
If someone has different new or gently used vintage ALPS-switch board that's a bit less common than a Dell AT101, then I'd consider that as well.
