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.
2) Any
software about?
Most HP software came on ROM modules that plug into a ROM Drawer,
There are a few interesting ROMs for this machine. Many of them are
'system extensions', like I/O drivers, Plotter functions, Mass Storage
functions (you can use HPIB disk and tape drives with it if you have an
HPIB card), etc. There was certainly also an assembler ROM, but I've
never managed to get that one.
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?)
