While dumpster diving at the end of a radio rally
(what,
doesn't everyone do this?) I found, in with the usual PC
scrap, an HP 9121 dual disk unit.
Right...
The unit powers and a small LED flashes five times but
that's as far as I've got because I've not got anything
to plug it into.
I take it I can use DSDD 3.5" disks in this and that with a
Yes. IIRC. the 9121 is actually a single-sided unit (the 9122 and 9123
being the double-sided versions), but obviously you can use DD disks in
it. It is double density, but not high denisty.
General Instrument HPIB card and some hand rolled code
I can
try it out. Anyone done this? Any pointers to where to start?
Any online docs for the command set/protocols?
It's going to be either SS/80 or Amigo protocol (I forget which). And
I've never found docs one either on-line (I have some printed
documentation from HP on this, which I guard with my life -- it's that
hard to find!).
