Speaking of paperclip... I may have found the ROMs for
both Paperclip and
Visicalc on the PET computers. Does anyone know what EPROM would fit the
ROM sockets in a PET? I've tried crossing the numbers on the ROMs and
can't learn anything. Does anyone have a schematic of a PET mainboard?
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.
