Peer reviewedMetz, Roger N. – American Journal of Physics, 1982
Describes a microcomputer-based multichannel analyzer (MCA) in which the front end is connected to a microcomputer through a custom interface. Thus an MCA System of 1024 channel resolution, programmable in Basic rather than in machine language and having moderate cost, is achieved. (Author/SK)

Peer reviewedPowers, Michael H. – Journal of Computers in Mathematics and Science Teaching, 1987
Discusses various types of transducers and explains the use of a photoresistor in sensing light. Describes various hardware and software combinations which can be used with photoresistors in science laboratory experiments. Presents general applications of this instrument in light-meter, solarimeter, and colorimeter experiments. (TW)
