Curt,
On the 4000-200 on the far left side of the QBus slots
is
a slot with 2 connectors, one appears to be a standard
SCSI-1 connector and the other is an inverse SCSI-2 connector
(labels Bus 0) with a terminator on it that lights up on power
up.
The first one indeed is a SCSI connector. The second one is the
DSSI bus connector, connected to bus #0. It should be terminated
(with the lighted term) unless you have an external storage cab,
which then in turn has the term.
The SCSI connector, however, is NOT usable for what you're doing.
The BA440 box (which is what your cab sounds like) has provisions
for changing its internal (DSSI) bus into a SCSI bus, for example
to be used with the KFQSA controller. That way, you can use SCSI
devices with the VAX by mounting them in the old DSSI rails.
The VAX does _NOT_ have a SCSI controller by default; unless you
have something like a KFQSA, Dilog or Emulex SCSI-to-Qbus controller,
you can NOT use the RRD43.
Sorry to be the bringer of Bad Newz (tm)..
Cheers,
Fred

Fred,
Thanks dude and no your not the bringer of bad news, your just helping me
relearn all of this, I used to work for Bay State Computer Group almost 10
years ago, and while most of my work was building and installing
SparcServers, I did get to do a lot of MV3100's and MV II's as well as setup
DECservers so I am very rusty at all of this and while it's disappointing to
hit another bump in the road to getting this system up and running, at least
I'm learning a lot along the way, I will see if I can scrounge up a KZQSA or
maybe a CMD443 board. I have an M5976-SA but the system doesn't seem to
like it and I did some searching and I don't think its compatible with the
BA440 chassis.
Thanks for the fast response, this is fun :-)
Curt

New subject: Wanted: KZQSA Adapter
Well thanks for Fred for helping me out with my DSSI/SCSI question, now I
just need to find a KZQSA adapter for my 4000-200, I just did some Google
searches and the current DEC dealers (aka - ripoff artists) want around $150
for a controller which is insane IMHO given the fact that I picked up a
fully loaded 4000 for $50.
Anyone out there have a spare board for sale or trade??? Let me know,
thanks.

Never mind, I have an M5976-SA which is a KZQSA, sorry.... Anyone know
how to configure this beastie and get the system to see it???

The KZQSA is a
dump, non MSCP SCSI adapter. You need special ROM support
in the CPU to be able to boot from it. The KA660 may not have this
support. What you really want is a MSCP emulating SCSI adapter like my
Dilog SQ706A. But this adapters are made out of pure unobtainium.
