To use HPIB mass-storage on an HP 1000 you should be

12821A interfaces are quite common, I have several extras.
Are you offering? I'd love to take one or two off your hands.
As for cables, the 12821A cable has a massive ferrite
core and a
grounding lug that the 59310 cable does not have. But I believe that
the two cables are electrically compatible.
I know I have a 12821A cable that was cut, and a replacement connector.
(if your up to building your own)
Yes! If your offering, I'll take you up on it. I have extra card edge
connectors, but not the IEEE-488 ends.
I would strongly recommend you try to use the 12821A
interface with your
floppy, you might find that the 'CS/80' boot loader rom supports that
drive.
If so, the loader ROM will only work with the 12821A board, not the
59310B.
That sounds great. I can load the boot ROM over serial to test things,
and if it works, I'll look for a real ROM.
I can also point you towards low-level driver code for
both the 59310B
and the 12821A interface boards.
I'm interested in this too. I've been meaning to hunt for code, but have
not gotten to it yet.
HP-IPL/OS fully supports the 59310 interface for
instrument control.
It should not be too hard to write IPL code to talk to your floppy disk
drive and debug the thing from high-level code.
12821A code support is not currently in HP-IPL/OS, but I do have tested
and working low-level code for CS/80 disks that could be patched into
a working CS/80 disk driver, and at that point IPL would have 12821A
support all the way up to a crude DOS and file system.
cool! More things to play with. :)
