What is that controller chip on the early Winchester
controller boards. That was a 64 pin part.

Yes Rockwell did. The calc chips used in some of the early calcs were

Ti was not first unless your talking about the first complete
microcomputer on
a single chip (excluding display drivers).

They used 42 pin quad-in-line packages. I don't think Rockwell had any
parts with more pins than that until very late in the 1970s.
to be offered in a 64-pin DIP package. The
TMS9900 didn't go into
production until 1976.
Some of the Rockwell PPS-4/1 parts were bristling with pins, but I don't
recall how many.
