I have programmed continuously since 1964 in technical fields. I have used many high-level languages as well as a number of assembler and machine languages.

Since 1971, I have been designing computer hardware using transistors, op amps, integrated circuits and ready-built microprocessors.

I have attached many devices to computers; here are some examples:
    analog recorders
    buffers that store digital images
    sophisticated interactive devices such as 3-D joysticks
    microscopes
    stepping motors
    large induction motors
    3-D displays
