Folks, I'm restoring an 11/34A. One of the MOS memory boards it came
with is a circa 1979 Motorola model "MMS1117", variation "58 PC"
(64KWords / 18 bits / w/parity). Would like to know if anyone out
there has configuration information for this seemingly uncommon board?
It's a very high quality board and has socketed RAM, so it'd be
especially nice to be able to keep using it. It has 5 switch packs
(only 2 of which have markings) and at least a dozen jumpers.
I've only been able to locate performance specs for it at:

.... which are excerpted here:

.... and a photo of the board is here:

... a photo of the system itself is here:

Any help, very much appreciated. Thank you,
John Singleton
