I have dug out an old SCSI hard drive from 1997 that may
have some interesting stuff, most especially the source
code for the SGI Iris flight sim demo. I have a Linux
system with an Adaptec 2940 (aic7880) that has two
connectors on it. It SEEMS from some probing that the
50-pin IDC connector on the top of the board is
single-ended SCSI (it seems to have mostly grounds on one
row of pins). Same for the drive, which is a Quantum
ProDrive LPS. The drive spins up and does some seeking
right after power-on, so it sounds like it is
working. But, I can't seem to find that the drive is being
recognized by the aic7xxx driver.
So, looking at /proc/scsi/aic7xxx/## I see the device
addresses all show just the negotiation settings,
and /proc/scsi/scsi just shows my SATA devices but not the
real SCSI ones.
I have the right cable to plug my old HP scanner into the
mounting plate Honda connector, and it shows up
fine. I could try getting a Honda to IDC-50 cable, but I
thought the IDC50 connector on the board edge OUGHT to
work.
Does anybody have any suggestions on what to try?
Thanks,
Jon
