Does anyone have an electronic copy of the SCSI-1 spec (scans or OCR)? I'm
homebrewing some SASI stuff, but figured it'd probably be possible to add SCSI
support on the same board (hence the hardware parity question yesterday).
I suspect the latest SCSI spec *is* around as a PDF, but 90% of it's likely
not relevant to dealing with vintage SCSI devices! :-)
Failing that, I suspect that some device manuals (such as disk/tape bridge
boards) might have useful SCSI documentation within - so recommendations
welcome! (I've got a few OMTI, Xebec and Emulex ones here, but despite calling
themselves SCSI they tend not to cover arbitration, parity, unit attention
etc. and are more like SASI in nature)

Well, it's not quite what you asked for, but I do have a disk-drive
manual from Seagate that looks like a fairly decent SCSI spec for those
aspects implemented by the drives it covers.
It does cover things like arbitration. It looks to me as though a good
computer electronics tech should be able to build a SCSI interface
sufficient to talk to the drives using just this manual - though I
haven't actually tried it, so there may be something I'm missing.

afraid it's a PDF, but that's what I've got).

I have a SCSI disk drive manual M2244S/SA/SB M2245S/SA/SB M2246S/SA/SB
which if I remember correctly has a lot of good info (not scanned yet)
nag me if needed

I collected some SCSI specs from the internet before start the MSCPSCSI
project. There is a SCSI2 spec on-line, which covers SCSI1 commands (those
'short' ones). I will check my computer after I get home.
Another good place to start is to get NCR 5380 manual and look at those
open-source 5380 drivers. This chip is as simple as a parallel port and I
think you can even find schematic/CPLD code of it. I bought a 5380 based ISA
card, just in case I want to integrate the SCSI port in CPLD some day.
