Six months later I was working for GCE, the manufacturer of an arcade video game machine with a monochrome vector display that performed amazingly well considering that it was little larger than a 10-inch television set and cost only approximately $100 to manufacture. I was right at home, in charge of the design of the analog circuits. I made two trips to Hong-Kong and Taipei to train the factory technicians. Then Milton Bradley bought Vectrex™ and took it out of state.

     The Chinese technicians had trouble with the English language. But we 
     soon developed a common understanding based on head ("yes" and "no") 
     and hand signals, punctuation marks ("?") and, most of all, schematic 
     diagrams. Travelers beware: "yes" in Chinese does not always mean 
     "yes". It can also mean "I hear you and I am thinking about what you 
     said."

     The Vectrex™ used integrating vector generator circuits. They were 
     subject to drift and I offered to use my drift-free "homebrew" 
     interpolating vector generator circuits. I also was disappointed with
     video arcade games -- a waste of good technology -- and proposed that
     the Vectrex™ be provided with software for biofeedback and 
     psychological studies as requested by a therapist. On my own, at home,
     I designed and built circuits and software for alpha wave biofeedback.
