Acquiring multichannel analyzer spectra with a mini computer

Spectra are produced on a multichannnel analyzer from biological samples with monochromatic fluorescent X-radiation. This mini-computer system is designed (1) to provide spectral data in a form immediately usable for computation, (2) to provide a great number of spectra stored on magnetic tape, (3) to examine the spectra in the laboratory before committing the spectra to tape and (4) facilitate the examining and manipulation of data in the laboratory. The spectra on the tape are used in high-level analyses. The mini-computer can examine parts of a spectrum, plot and print the values, identify and integrate peaks, all at the user's discretion.
