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).
I have no idea what a "dual QIL" is, but Rockwell having 52-pin QUIPs does
not in any way refute the idea that the TMS1099 in 1975 might have been the
first production IC in a 64-pin DIP.

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.
