1st Word and 1st Word Plus were word processors developed by GST Computer Systems in the 1980s. The original package, 1st Word, was given away free with all Atari STs. The later 1st Word Plus was sold by GST and was more advanced.
1st Word first appeared on the Atari ST in 1986. 1st Word Plus version 2.0 credits Mike Bees, Howard Chalkley, Phil Champ, Martin Dickens, Chris Scheybeler, and Alun Gladman.
A PC version was produced that ran using Digital Research's GEM interface. Other versions were produced for the Arthur and RISC OS operating systems for Acorn's ARM-based machines, the Torch XXX, and for Digital Research's Flex OS.
