Yeah. I've got some round here: they're in the early Macs. I've also got
a newer version of it (SMT) inside a JTEC terminal
as fast. It just requires a
little different logic.

I have to tell you that I tend to ignore what you say when you start arguing religion.
You didn't even give a hint as to why you think PL/X is better than C.

The 4004 may have used serial adders, but the 8080 used parallel. Most of
the PDPs used parallel also. In fact I am sure that all the PDPs built from
the late 60s on used parallel adders. Back in the 60s most systems used
serial adders since they used transistors. It takes a lot of transistors
