Subject: Wanted: Info on MMI third party boards for PDP-8/E

I have gotten my old PDP-8/F up, and I've restored my asynch boards to
good condition, but I have a problem with memory:

In addition to an 8K core module made by DEC, I have 3 8K solid state
memory modules made by MMI.  Of these, two work well, but one is broken.
I'd like to repair it, but I have no prints for the board.  Does anyone
have prints for a board with the following self-description?

    MO-V PL/PDP-8
    303-0112-0010   -- the last 4 digits are rubber-stamped -- board revision?
          M         -- the M is really an MMI logo.

On the back side, the board has the following text:

    304-0112-001  REV.C
    MADE IN USA  7622    -- more rubber stamps, a date code for week 22, 1976?
    SER. NO. E6 0207     -- more rubber stamps.

Any and all help I can get would be appreciated (although, I admit, I've
already got enough good memory to put 16K on each of my PDP-8 machines, so
what more could I want?  That's quite a bit, after all!)
