    I wouldn't say *most* software came on ROMs. There were a lot of ROMs
for it but they usually included low level routines for handling plotters,
printers, special I/O, matrix routines and the like. There is/was TONS of
software for the HP 85, including Training Paks and Solutions books. There
was also a lot of software availble directly from HP that they wrote to
control various HP test equipment.

   There are a number of other interfaces for the 85. There are both DCE
and DTE RS-232 interfaces, a GPIO (General Purpose I/O with 16 parallel
lines that can be used as input or output or both) and a HP-IL interface.
There's also a plug-in MODEM for it.

   Probably the strangest plug-in is the CPM module. It has it's own Z-80
CPU and 64k of memory. I just got one but I don't have a manual for it and
I haven't had time to experiment with it. (Does anyone have a manaul for it?)
