Idiot! "IC"s NEVER "had less than ten transistors", you stupid
twit.

The very first IC HAD ten transistors, so there were none "that had
less".

The Diode Transistor Logic (DTL) single flip flop ICs that I used in
1969 had less than 10 transistors!

Don't worry. He does that all the time and is quite reliably wrong.

One of, if not, the first commercial ICs was the Fairchild-Micrologic
type "F" (flip-flop) stuffed to the brim with a mind boggling 4
transistors.

They also had the type "G" nor gate.

T.I. made similar 'chips', and there is debate as to whether theirs or
Micrologic's was 'first', but their early production was entirely
consumed by NASA and the military so many consider that not
'commercially available'.

I vaguely remember that I was playing about with "Ferranti" packaged
circuits, circa late 60's that had four transistors. I also seem to
recall that the colour of the plastic indicated what type of circuit
was in the package. Oh those fun days... :-)


Remember ICs in round metal cans? I also remember an MIT open house
where they had a flip flop in an IC in a dipped (epoxy?) package in the
late 1960s. They used it in a decade counter.
