Tony Cole's Cray-1

Remember Tony Cole, the guy that bought the Cray from Livermore and sold
the boards in acrylic frames as "memorybilia"? I just got one of the
memory boards second hand! It'll come in handy if I ever acquire a
Cray-1, but in the meantime I'd like to document it as well as I can while
info is still available. I don't suppose anybody has schematics.

It's basically a solid slab of copper (doubles as a heat fin, I suppose)
and is populated rather sparsely by chips with date codes from '80 and
'81. The chips seem to be from Fairchild primarily (the 32 F10470's look
like they might be RAM). From Mr. Cole's "limited edition" markings, I
gather that there were 400 of these boards in his Cray-1.

Any idea how much RAM is on the board? Can I interface the board to my
Sinclair ZX-81 to create the world's most perverse hybrid?
