The "bit-serial" version you are thinking of
is probably the PDP-8/S. It
does have a 1-bit serialized ALU. It was made with the same technology as
the original "Straight" 8 - R-series, S-series, and W-series FLIP-CHIPs
(transistors, not TTL ICs like the later M-series).
Side-tracking here, but I have a few K-series modules and I see at
http://research.microsoft.com/~gbell/digital/timeline/1967-2.htm
they are described as having high noise immunity for use in industrial control
systems. Are these something like the discrete equivalent of HTL ICs? Anyone
know if there was a standard/common DEC processor built from them, or perhaps
an industrial version of such a processor?
