Programma International was a software company which was founded in the 1970's by David Gordon. The company was famous for their tapes and the quality programs they provided. Everything from a Clowns & Ballonons clone to Space Invaders to programming tools for Forth.
In 1980, the company was sold to Hayden Publishing. While David Gordon went on to do other things including starting Datamost, another software / manual publishing company.
In 1983, Hayden Publishing went out of business, leaving the entire Programma International in the black void that is abandon-ware.
