I tried posting this to alt.sex.fetish.hardware.DEC but it seems my news
server doesn't carry that group anymore. :-|

Since I moved house recently I now have more room and will soon do an
inventory of my hardware, put some new stuff into operation, take some
stuff out of operation, give some stuff new tasks etc. I will also draw
the line and give away stuff which is "too old" for me. (Actual age
isn't as important as the technology involved.) What I have in mind as
"too old" would be something like VAX machines slower than the
VAX(station) 4000, such as various models of the VAXstation 3100; DSSI
stuff; thickwire and BNC ethernet; black-and-white monitors (but not
monochrome terminals) etc.

During the inventory, I plan to test the stuff so that I know what works
and what doesn't, how much memory a machine has etc. This is all stuff
which I got (most probably for free) but no longer need myself.
However, I think there are folks interested in somewhat older hardware
than the stuff I am using at home now.

I don't know when I'll be done---probably by the end of the year or so.
This is thus just an advance notice. I can store the stuff for a while,
so it's not urgent. I am not far from the Autobahn near Frankfurt am
Main in Germany. If I happen to be coming your way and have the time, I
could bring it by, but otherwise you would have to collect it yourself.
I think the cost of shipping would be prohibitive.

Please send me an email so that I can get an idea of how much interest
there is. My plan is to make an announcement after the inventory and
then distribute stuff on a first come, first served basis, but if anyone
is really, really interested in such stuff (I won't be able to say more
until after the inventory) and sends me an email now, then I'll give
such folks first choice before making the announcement later on.
(Please indicate whether you are really, really interested or are just
expressing general interest and might want to have something after the
announcement later on.)

Phillip
I'd be interested in DSSI equipment, like disks and microVAX systems.
IIRC a microVAX 4100 is the same as a MicroVAX 3100 with DSSI enabled
instead of SCSI, right?

I'll keep you in mind.

Not sure; I don't have any 4100s.

Hello Phillip,
I'm also interested on your DEC equipment. I think you already
received my email some day ago...
Please let me have a list!

In the absence of other contributions...

There were various flavours of 3100. One of the last members of the
3100 family was indeed closely related to the MicroVAX 4100, indeed if
I recall correctly the same motherboard was in both, and the (main)
difference was indeed that the 4100 did DSSI. A "Systems and Options"
chapter from the relevant era might reveal more.

Just to add some detail to the above answer.
The 3100 series was called MicroVAX, but the 4100 series was called VAX
4000 model 100 (or 100A, 105A, 106A and 108).
The main system board was indeed the same on some models of MicroVAX
3100 and VAX 4000-10*.
And like earlier said, the main difference between the two model series
was two SCSI buses on MicroVAX and two DSSI buses on VAX 4000-10*. The
VAX 4000-10* had also a SCSI bus.

The name 4000-100 led to endless confusion when we also had a pair of
Alpha 4100 systems. IIRC we ended up calling the latter "Forty one
hundreds".

The KA50 and KA52 (I may have those numbers wrong :-)) were indeed the same
motherboard. More than that, with a simple command you could reflash either
into its evil twin.

That made a difference (IIRC) to licencing.

I don't recall whether the DSSI interface or the Qbus adapter worked in
both modes or just the one. They may have been addon boards internally
anyway (so you may not have one or the other).
