Well, I have decided to stop playing with my hardware for a while and
get back to playing with software. :-)
In order to do this I am building three (maybe four)
PDP-11's. I have an 11/93, an 11/73 and an 11/23+
(and maybe another 11/23 or 11/73). BUt, I have run
into a small problem. Memory. (both the systems and
me!)
My 11/93 has 2 meg internal and I would like to bring
it up to 4 meg. The others I would like to see with
4 meg if possible. (except the last one which I may
deliberately keep at 128KW.)
I have a number of different memory modules. Mostly
DEC but a couple third party. Here's the problem.
None of them are reflected in any of the documentation
I have been able to find so I can't configure them away
>from their defaults!
Here's a list of numbers:
M7551-AC - All the docs I can find seem to refer to
AA or AB and jumpers and switches are not
in the same locations.
M8067-LB
M8067-LF
M8067-LJ - Same problem. I can find no documentation
for any -L boards and these don't even resemble
the pictures I find.
And then I have two non-DEC module that are unlikely to
have any documentation still floating around for.
Camintonn CMV-1000 -- As funny as it sounds, this one
looks more like a DEC MSV11-QA
then the DEC ones do, but not exactly.
And one who's maker is only identified by a logo that
looks like 2 interlaced stylized S's. Model Number
is: 980110014-201 Rev E.
Anybody got any pointers to help me configure some of this stuff?

So, one of the things I have along with my 11/45 is an RK05 alignment
cartridge. Unfortunately, its seems warped -- rides up an down a few
millimeters in each direction as you turn it in an RK05 drive. :-(
Is there any hope for bending one of these platters back more into true
(maybe using a rig like they do with bicycle rims, etc?). Or is it just
basically junk at this point?
I wouldn't really care, but it's an alignment cartridge and there can't
still be too many of these still around out there... So it sort of sux
to just write it off. I'm assuming that if I had to release the media
>from the hub in order to true it, its value as an alignment cartridge
would be lost anyway.

You've looked in EK-MSV1Q-UG-002, right? That seems to cover a couple of
different revisions.

The M8067-L variants are all MSV11-PL (512-Kbyte QBUS MOS memory). The
last letter usually indicates the vendor of the MOS chips used.

I too couldn't find any documentatin for this; there is the 'SMS 1000
Microcomputer System OEM Manual', which says how to configure one for a base
configuration. I started to work out what the configuration switches do, by
experiment, but I got distracted before I finished. I have found my notes
>from this exercise, and can send them to you if they are of any use.

Complement. I already have a large stack of empty bezels, acquired to hold
the indicator panels... :-)
Although Dave Bridgham has been playing with the CNC mill at his local
makespace (he's already turned out a bunch of light shields for me), and he
now has a prototype of a thing which combines the bezel and light shield. So
maybe the empty bezels will instead get paired with blank sheets to make a
stack of 1/2-width blank panels. Someone still makes that 'pebbled' sheet
like what DEC used in blank panels, but we haven't acquired any yet to see
just how close a match it is. (Anyone happen to know?)

Two H960's, actually - it looks like there's another one in front of that
one.
If the half panels are for sale, I'll take them! :-)
