[1] ALL-IN-1 was advertised as an office automation system including functionality in Electronic Messaging, Word Processing and Time Management.

[2] ALL-IN-1 was designed and developed by Skip Walter, John Churin and Marty Skinner from Digital Equipment Corporation who began work in 1977.

The first version of the software, called CP/OSS, the Charlotte Package of Office System Services, named after the location of the developers, was released in May 1982.

Digital then made the decision to move most of the development activity to its central engineering facility in Reading, United Kingdom, where a group there took responsibility for the product from version 2.0 (released in field test in 1984 and to customers in 1985) onward.

He oversaw the growth of the product culminating in over $2 billion per year in revenue and market leadership in the proprietary office automation sector.
