In the 70's, TRW made a fast (for the day)
fully-combinational bipolar multiplier that was
packaged in an oversized DIP with a giant TRW logo.
Chamberlain's "Musical Applications of
Microprocessors"
has a picture of one. I have no idea what this
particular chip is, but TRW did make chips with this
"mock up" look.
