The cool fun expressive side of the industry on an old Rockwell calculator chip (11483) designed in 1970’s and repurposed for 1980’s as new uses in industrial automation appeared. This is a very unique 4” Chip Art wafer full of several engineering doodles from USS Enterprise, Alfred Hitchcock cameo pic, a bug and others all on the same wafer. There’s even a reference to Leave it to Beaver late 1950’s tv show! Chip Art was very big with many early circuit engineers during the 1970’s into the 1990’s when engineers added their own personal touch to their work during a unique era of chip design.
