“…Furthermore, a researcher can easily control the I/O ports by simply putting a bit pattern on the control registers. Programming for I/O processing is also simple by using PEEKing/POKEing at each I/O register address (Osaka, 1979a(Osaka, , 1979b(Osaka, , 1980. This type of a bit-addressable I/O register controls the LCS (Nitten Corporation), pulse motor (PM; Nippon Pulse Motor Corporation, PA62), glow modulator (GM) tybe (Sylvania Corporation, R1131C), monochromator (M; Jobin-Yvon, H20 with I/O slit width of I mm), and circular neutral density wedge (CW; Kodak, A6020).…”

“…This problem can be resolved in two ways. The first solution is to expand the number of I/O lines available; this is normally accomplished by adding additional I/O chips (Osaka, 1980). While this provides the necessary expansion, it also results in increased execution time, since each line must be addressed and then examined.…”

While most small microcomputers are powerful enough to control intricate experiments. a major limitation of many is their limited 110 capability. An interface for the KIM-lor similar small microcomputer is described that provides for up to 128 or more inputs. The basic components of the interface are a series of shift registers through which the incoming data are manipulated and read by the microcomputer. Provisions are also made to latch the incoming data, allowing detection of very high rates of or even simultaneous data input. The interface is modular in design and can be expanded by increments of eight inputs. Use of the system to monitor a large number of running wheels is discussed.

“…Other solutions for connecting photocell inputs to microcomputers have been described (Dillon, Millman, Tombaugh, Ferguson, & Bezanson, 1979;EmmettOglesby, Spencer, & Arnoult, 1982;Osaka, 1980;Thompson, 1979). The one presented here, however, is relatively simple, and is easily constructed.…”
