PDP-8 /e/f/m memory

[Allison]

Looking for information on a QUAD width omnibus RAM card.
Not interested in hex wide as it doesn't fit the older 
Omnibus 8E or F boxes.  I used to have a 4kx12 card that
used 2102 type rams but had no data for it. That went to
and earlier 8E I had.

Even schematics would help.  In the end I may do my own as 
a pair of 61256s will certainly fit the bill and barely fill
a corner of a board.
