Some Applications of Small Computers to Optical Spectroscopy

Extract

At Lick Observatory we have begun to use small computers as a basic element of some electronic instrumentation systems. It is felt that computer technology has advanced to the point where the results are likely to repay the investment. In our approach and choice of machine, we have tried to benefit by the experience gained over the past several years by nuclear physicists in nuclear spectroscopy applications.

The major factor involved in choosing a small computer is probably one of economics. The initial cost is important, but, equally important, the costs of maintenance, programming, and the connection of peripheral equipment must be considered. A computer is sufficiently complex to require at least one person in an organization to spend considerable time familiarizing himself with the details of the machine. These extra costs, required to realize the potential of any computer system, are likely to exceed the initial purchase price of the system! It is important to take such factors into account when choosing a machine.
