[CDC6600 in a FPGA]
As the 6600 was entirely built with discrete
components, not chips,
and yet had to be physically relatively compact, I doubt if it had
much more than say 20,000-25,000 gates. Nowadays that isn't anywhere
near high end of the FPGA ranges.
I don't know how many gates, but the Book
"Design of a Computer CDC6600"
states on page 20: "the entire 6600 Computer contains approximately
400,000 transistors". It used "Direct-Coupled Transistor Logic" so there
where way less then 400,000 gates.
