#11 Lord help me, a 12" Versalog.
I was working at the SAGE store on the Gulf Freeway in Houston in the camera dept, where calculators were sold, during Apollo-Soyuz. The Nasa guys brought the Russian engineering team to the store on a shopping expedition. The Russians bought every calculator in the building.
One of the handlers, an AF colonel, shook his head and said "We probably just tripled the Russian's number crunching ability."
