IBM MagCard II Selectric Typewriter
The IBM Magnetic Tape Selectric Typewriter (MSTS) was introduced by the Office Products Division in 1964. This was augmented by the release of the Magnetic Card Selectric Typewriter (MCST) in October, 1969. The $10,000 MSTS was believed more suitable for heavy data base merging operations, while the MCST was more appropriate for correspondence and memo writing.
The Mag Card, at $7,000 was instantly successful and spawned the Communicating Magnetic Card Selectric Typewriter in July, 1971. Unfortunately, the CMCST used "Kentucky Code" which was incompatible with ASCII and found only limited acceptance.
In April, 1973, an even more successful machine was introduced, the $11,000 MagCard II was introduced with 8,000 character memory, corrections capability and a card reader able to handle a pack of 50 magnetic cards. A communicating version was also offered. A proposed video display upgrade was rejected in favour of the "Rio" project which resulted in the Office System/6 introduced in January, 1977.
Although IBM had created the Word Processing concept at its Waco, Texas office in 1964, by the end of the 1970's it had yielded leadership to Lexitron (1970), Vydec (1974) and Wang (1975). The Displaywriter released in June, 1980 was one of the last projects completed before the Division was disbanded at the end of 1981.
