Actually, it's on the VAXstation 3100/M30 (this model is just labelled as
VAXstation 3100), the VAXstation 3100/M38, and the VAXstation 3100/M76--at
least all the ones I've ever seen--which include the half-dozen sitting
here on top of my desk.

I believe the oddball 68pin connector is also on the VAXstation 3100/M40
and M48 as well. The VAXserver 3100 I have has a 50pin centronics SCSI
port. I believe most if not all of the MicroVAX 3100s did have normal
SCSI connectors. The VAXstation 3100 are just a bit odd. And the thing
with the VAXstation 3100 68pin connectors is that they are *not* the same
pinout as required by the newer 68pin SCSI.

If they've actually got a MicroVAX 3100 and not a VAXstation 3100, it
shouldn't be a pinout issue. As for reliability issues with my VAXen,
I've never had any problems with their hardware with the excepting of a
disk or two finally giving up their ghost. Nothing out of the ordinary
though.
