     National RQ-8100, Cassette Program Recorder.    Made in 1985 by "Matsushita Electric Trading Co., Ltd", Osaka, Japan. This is a portable cassette recorder, which could also be used as magnetic storage for computers. Dimensions 202 x Tape 119 x 40 mm. Weight without batteries 600 grams Power 6 v, four AA batteries or the mains power supply. I do not know how much digital information can fit on a compact cassette, apparently, by modern standards a little, but then the computers were not like now. Wiring the recorder is collected on a single chip type BA526, and four transistors D636. Kinematics is very simple, but there hitchhiking. The instructions contain information on the parameters.
     The device has got to me in a good working condition. Quality of recording - playback is good. Outwardly, he also remained very good, even has the original packing box, and instruction manual.
