Description:: Much of the Apple II's success in the late seventies and early eighties was a result of VisiCalc, the original computer spreadsheet. VisiCalc helped differentiate the Apple II from cheaper computers like the Atari 800 and Commodore PET.

Odd, I have VisiCalc in the other room for my Atari 800. It required 24 KB and a diskette drive, had a rudimentary copy protection scheme, and '*" characters provided the charting graphics. I don't remember it being as low as $100.

It's amazing how responsive the software is on a machine running under 2 MHz. I also have Perfect Calc running on a 4 MHz Z-80 CP/M machine and it's sluggish.
