By an interesting coincidence, I care a good deal about this myself
just now - I just got a SCSI card for my hp300 box (a 320) only to find
that the ROMs don't know how to talk to it. My only boot possibility
is thus HP-IB. I have one working 7958 and one dead 7958, and I don't
trust the working one to stay working. An experiment just now
indicates that I don't need to get more than the bootblocks over HP-IB
(the bootblocks on the working 7958 are capable of loading the kernel
I was looking at building an HP-IB pseudo-disk out of a peecee parallel
port plus some glue logic (I've done parallel-port-plus-glue-logic
hackery in the past, such as my Tempest spinner interface). But I also
have an IEEE488 SBus card which uses a chip for which an ISA driver
exists in NetBSD. I'm going to poke at it with the existing ISA driver
for guidance and see if I can get it to do anything.
And if not...I may resurrect the parallel-port project.
But I probably will need CS/80 docs of some sort. There apparently is
some MI driver code for HP-IB disks in NetBSD, which is likely to help.
Unless there's some kind of CS/80 spec among the doc we have online...?
