Another Unknown Board:

[pilgrimer@my-deja.com]

I picked up a ][+ today full of boards and one I cannot ID:  here are
the specs:
rectangle with no plugs, DIPS, pins or other ... was in slot #2:
Has 8 chips on it and no markings denoting the use or brand name.
Chips are arranged in 3 rows of 3 3 2 top to bottom. Chips are marked
as best I can tell (older eyes):
top row: DM74LS74N,  74LS04RC,  DM74LS00N
2nd row: ?? (no markings and larger, 16 pins, says DA1 by it on board;
DM74Ls00N and  74l530PC
bottom row: DM74LS154N   and   the last chip has 3 markings;  8108,
C28611m and DRPU001
Guys....what the heck is this thing ?
