The PDP-8 was a 12-bit architecture, and bigger than a file cabinet only if you had a very large -8 configuration (lots of peripherals to fill up a rack) or a very small file cabinet. Might it have been a PDP-11? Early models of that family (before LSI) were usually at least one full-height 19" rack and often several, and the primary data paths are 16-bit it does address 8-bit bytes (in memory). -- - David.Thompson 1 now at worldnet.att.net
