CompuPro RAM board settings

Hello, all:

        I just got a CompuPro RAM20 memory board with no manual. I'm looking
for the DIP switch settings specifically, but a copy of the manual would be
very helpful.

        It's missing two chips...a 74LS74 at U6 and a 25LS2521 at U10. The
memory array is 8 columns of 8 chips, type MM2147J. I'm thinking that these
are 2kx1 chips, resulting in a 16k board.

        Any help appreciated. Thanks.
