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?
