No. That's when you are on a q-bus. This is a Unibus box. Then the CPU
goes into slot 1 and the memory cards goes into slots 2 and 3.

I have a 7300. I've come to learn a bit about the 3B1,
which could be considered the same thing (?).
I have a load of disks and docs for the 7300?.
Unfortunately they were all stored improperly and are
worthless. Being I already have the media (and can
prove it) I'd like to have working images of these
disks. Anyone have a clue?
My hard drive does work, but is a bit flakey maybe :(
The thing is a pitn to open up :{
I'd be very interested to hear from humans who are
knowledgeable of these units, and more so by those who
are currently playing with them.

We seem to have come down to one fudamental question.
That is to say whats the differnce between the backplane in an 11/84 and
that in an 11/94?
I can confirm the actual systems were as stated above ie
KDJ11-E M8981 in slot 1
APS module M7914 in slot 2
Nothing in slot 3
So how can we tell if the first three slots in each type are compatible?

Figure 8-6 in EK-PDP94-MG-001_Sep90.pdf shows a PDP-11/84-A backplane
with the MDM M7677 in the MDM slot, the KDJ11-BF M8190 in slot 1, a
MSV11-JB/JC M8637-BA/CA in slot 2, and a MLM load module M7556 in slot
3. Not clear to me if the MLM in this case could be replaced by a
second MSV11-J.

...you tell me. It's not in the greatest cosmetic
condition, but it worked (the last time I checked).
It's very heavy. Shipping would be catastrophic...

Pretty much. Architecturally, they're the same. The usual
distinction is the 3b1 has a "hump" to accomodate a
physically larger disk drive. There has been a suggestion,
though debated, that the 3b1 also has a beefier PS.

That's a good question. Because they contained
UNIX SYS V R2, most everyone was pretty careful
about throwing around copies. So I don't know of
any online images of them. Your best bet might
be to find someone who has a set they'll send
you, or perhaps a set they've backed up.
In general, the first place to look is Peter da Silva's
page: http://unixpc/taronga.com
> My hard drive does work, but is a bit flakey maybe :(
There's a classic issue of corrosion on the PS
connector. That might be part of your problem.

I used to do quite a lot with them, but haven't fired one
up in probably 5 years. I used to maintain the archive
that Peter maintains now.
