Abstract

Some applications of microprocessors at Lick Observatory are discussed. These include the use of an MOS Technology 6502 controlling a floppy disc to exactly emulate a magnetic tape (DECtape) system on our PDP-8I mini-computers. Other microprocessor applications in operation or under development include spectrograph controllers and an inexpensive control system for the Shane 3 meter Telescope. We also describe features of a new system for developing and debugging microprocessor controlled equipment. Our experience indicates that the costs of completing specialized equipment with hard-wired logic or with microprocessor logic are similar. A main advantage of the microprocessor appears to be that since the fraction of the cost devoted to hardware is so small, it will be economic to provide complete back-up systems for easy and rapid maintenance in difficult environments.
