I realize this a rare bird indeed, but would anyone just happen to have a
Varian 620/L backplane netlist hanging around?
Unless I missed it, the schematics on bitsavers do *not* have it.

In 1972, I wrote microcode for the Varian V-70 to convince it to be an
IBM 1130. Two colleagues wrote the I/O side in 620/f mode.
I can send microcode, and flow diagrams for it.
I have listings of the I/O simulator, but no electrons. I'll send that
to anybody who's interested, for the price of postage.

Dave mcguire has one at LSSM near Pittsburgh
