2732 on practically all PETs.

Early ones (ROM=6540) had no spare sockets

Early ones (ROM=2316) also had no spare sockets, but could take 2716
chips in place of the system ROMs

Late ones (Model = 8296) had some sockets that could take 28-pin 2764s,
but I think all the spare sockets were 24 pin for 2332 and 2732.
