Hi Bob - I have a OCR'd service manual with schematics.  There is also one on the KO4BB site

I can post mine if that one isn't sufficient.

Subject: [time-nuts] 5372A A7 CPU board

I have the CPU board 05372-6007 out of my 5372A this evening to replace the battery. While looking at it, I see jumpers for 64/256K and 512k/2M. 

I suspect the 64/256 is for the RAM as it is located next to the (non socketed) RAM. 

Does anyone have a schematic or listing of what all the jumpers are for?
