I was down to my local second hand store today and saw that they had two Model M's for a total of $7. Needless to say, I bought them immediately. The top one is from 1993 and the bottom one from 1988, both have two piece keycaps.
Both were fully working and in great condition except for some dirt and grime; the 1988 one was exceptionally bad. I think I even saw some cobwebs when I removed the keycaps... Anyway, after some hot water, soap and a lot of q-tips the -88 one looks like new, and that's what I'll bring home to my apartment this evening. The other one goes to my family that I was visiting this weekend.
When I cleaned the keyboard I found that in addition to the spacebar, both enter keys and the big + key had metal bar stabilizers, something that neither the -93 keyboard had nor the -91 board I use at home. Is this something that was removed somewhere between -88 and -91?
And also, the cable I use with my -91 board only have four pins, but the one on the -88 have all of them. Can I use the -91 cable with the -88 board, or will that mess something up?
