Looking on the
bottom I see :
Part No : 1395300 IBM
ID No : 2117313
Date : 12-05-1992 (C) IBM Corp. 1984
Doesn't it seem queer that the keyboard has got a "PS/2" plug while made
several years before the introduction of the PS/2? I suppose it's not a PC
keyboard, since there were no PCs around at that time into which it AFAIK
could be plugged.
1992? PS/2s were already in Generation III. PS/2s came out in late 1987.
