I have some very strange boards from a CNC controller
that had video and an 8080, but is made mostly of what
I think are DTL chips. All are in sockets. Send the
list, these are taking up space!
846
930
830, etc.
I am looking for some DTL chips to make a repro W706/W707 TTY
interface set for my Straight-8 and PDP-8/S (got *no* serial
I/O for them. :-( )

The chips there are:
W707
MC799 Dual Power Buffer (1)
MC790 Dual J-K Flip-Flop (8)
MC724 Quad Input Gate (5)
MC789 Hex Inverter (5)
W706
MC790 Dual J-K Flip-Flop (9)
MC789 Hex Inverter (6)
MC724 Quad Input Gate (5)
MC799 Dual Power Buffer (1)
Obviously, I'd rather find a real W706 and W707 than build my own, but
in the absence of any quantities of 35-year-old modules falling out of
a heretofore unknown closet, I'm forced to contemplate reproductions.
Thanks,
