VisiCalc was the first spreadsheet program for personal computers. It
was extremely successful, and pivotal as it was significantly
responsible for moving personal computing out of the realm of
hobbyists and in to the realm of serious business tools.

It was originally created by Dan Bricklin and Bob Frankston of
Software Arts and first released in 1979 for the Apple II. It was
published through Personal Software, who due to the success of
VisiCalc, changed their name to VisiCorp.

It was then ported to a wide variety of platforms including the Apple
III, TRS-80 series, Sony SMC-70, HP, Commodore, and Atari computers.
It was one of the first commercial packages available when the IBM PC
shipped in 1981.

After its release, a large number of spreadsheet clones appeared,
notably SuperCalc and Multiplan. It was later overtaken by Lotus
1-2-3 until Microsoft Excel claimed world domination.

This release is specifically for Atari Computers, and uses the Atari
800 single sided single density floppy disk format.
