Check SMC for it.
I hate sockets and try to avoid them, I've had equipment that
didn't use the machined pin sockets and most all had to be
rebuilt sans sockets at one point or another.
that will do
125ns easily. Or you could easily find a d765
off an old board or NOS from JDR.
Do you know of a WD37C65 data sheet on the web?
parts and the
requisite connections. Of the latter, the fewer the
better for both buildability and reliability.
Hmm what ever happened to sockets and
repairable stuff.

A good solution but this is a one-shot project so price is not a major
problem
A lousy one if you have a raft of TTL and few FPGAs. ;)
I have a few of the Lattice and Xilinx tools, older ones and the synario
stuff too. I just dont get all that excited about it. I've designed a
cpu
and built it years ago, it out of my system and not worth repeating.
Any cpu I'd do would need software and that means it would likely
be a copy of something... likely something I have.
