Programming concepts for the GeMSAEC rapid photometric analyzer.

Programming in a modified conversational interpretive language such as FOCAL provides the flexibility that is desirable when using the GeMSAEC Analyzer to develop analytical methods. Three approaches to the problems of interfacing the GeMSAEC Analyzer to a PDP-8/I computer and the modifications required to the FOCAL language are briefly summarized. The configurations of the computers and peripheral devices are: a 4K PDP-8/I with 32K disk and X-Y plotter, an 8K PDP-8/I with two 32K disks and storage oscilloscope, and an 8K PDP-8/I with cartridge tape storage and a refreshed oscilloscope display.
