No, the SCSI connector is just a strange DEC-only format. It
looks like a 68-pin SCSI connector, but it's not. You'll need
the special SCSI cable to use external devices.
Only on the M76 and later machines.

(a.k.a. the VAXstation 3100) or the MicroVAX 3100/10. The former has the
weird 68pin connecter, the later... well I don't know. I don't have one
yet.

I don't think the VAXstation 3100/10 is later than a M76, and it's got that
oddball connector. I thought it was the other way around. Also either the
DECstation 2100's and/or 3100's used the same cable.

Tell that to the VS3100/M30 :-)
I'm guessing its all VAXStation machines but its hard to be sure.
On an unrelated but still VAXish note. The BA123 chassis. Normally when you
open theses things on the right side (looking at it from the front) there
is a brass door that covers the card cage. Now I'm looking at one that has
a brass plate that covers both the card cage and much of the drive area.
When was this introduced?

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.
