- 9133 HPIB 3,5" Floppy (with disk inside as
well??)
The HP9133 is, indeed, a floppy/winchester combination. There are many
varients, the letter _after_ the '9133' on the nameplate is important.
Older versions have a single-sided drive and separate controllers for the
hard and floppy drives (and thus have 2 separate HPIB addresses). Later
models have one controller board and take one address.
- A LOT of software manuals but no hardware manual.
I have already found the only document at hp.com that told me something
about select codes, switch settings etc. But nothing about cable pinouts
etc.
Have you tried http://www.hpmuseum.net ? I don;t know if it's got
anything as late as this machine, but it's a pretty good site for old HP
computer manuals
I tried my 2648 terminal with the cable, without success. Perhaps my
terminal is broken or - what I think - the cable pinout is incompatible
to the "new" A600.
Assuming this is a normal RS232 connection, can you not just put a
breakout box on the line? That would tell you if the computer is sending
anything and which pin it's sending it on (i.e. do you need a null-modem
cable). For that matter, have you tried 'looping back' the terminal
(shorting pin 2 to pin 3 of the DB25, with it unplugged from the
computer, works on most terminals provided they don't need handshake
lines). If you do that, the terminal should display everything you type
on its keyboard.
