Teletype Equipment

Model 40 Dataspeed (c1980)

The first series of combined electronic CRT and high speed printer terminals produced by Teletype Corporation. These units worked very well with less maintenance than would be expected. the down side of these products was their large (and heavy) size, high current and heat dissipation. (not to mention the high pricing). The model 40 DataSpeeds were networked in many different applications through the use of "Cluster controllers" and digital data service units. The trademarked term "DataSpeed" originated with a series of high speed paper tape terminals that sent and received oil-treated punched paper tape at the chad producing rate of 1050 words per minute.
