TV Typewriter - TVT II - CT-1024 Terminal

CT-1024 Terminal

The original TV Typewriter was difficult to assemble and some of the ICs were going out of production so Southwest Technical Products decided to redesign the kit. The replacement was featured in Radio Electronics as the TV Typewriter II. This time readers did not have to order a set of plans, since the complete design was published in 6 issues starting in February 1975.

Daniel Meyer of SWTPC enlisted Ed Colle, an engineer who had worked at Datapoint on terminal design, to design the new TV Typewriter. The SWTPC CT-1024 Terminal displayed 32 characters by 16 lines without scrolling. It used common TTL parts and 2102 static RAMS. The boards were laid out with very loose part spacing and wide traces to make it easy to assemble. A complete set of option boards were offered including a serial interface. The keyboard was based on Don Lancaster’s design. The rest of the terminal was done by Ed Colle.

The design was finished by late 1974 and the kits were ready for sale by December 1974. The first advertisement for the CT-1024 appeared in the January 1975 issue of Popular Electronics on the page facing the Altair 8800 computer article. The CT-1024 was very successful because a complete kit with options cost only $275. It was replaced in 1977 by the improved CT-64 that offered scrolling and 64 characters per line of upper and lower case.
