CS/80 disc geometry

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...? /~\ The ASCII der Mouse \ / Ribbon Campaign X Against HTML mouse at rodents.montreal.qc.ca / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
