It was initially developed in a 6502 assembler running on the Multics time sharing system. VisiCalc was ported to several platforms, both 8-bit (and early 16-bit systems). In order to do this, the company developed porting platforms that produced bug compatible versions. The company took the same approach when the IBM PC was launched, producing a product that was essentially identical to the original Apple II version.
VisiCalc used the A1 notation in formulas.
VisiCalc suffered a severe loss when Lotus 1-2-3 launched in 1983, which took full advantage of the expanded memory and screen of the PC. VisiCalc sales practically ended overnight. The sales imploded so rapidly that the company was soon insolvent. Lotus Development then purchased the company in 1985, and ended all sales of VisiCalc and the company's other products.

VisiCalc does not require a CD key to be installed. You can use it permanently without having to purchase any product keys. Also, since the software is considered abandonware, it is legal to use! (So no need to worry about anything illegal)
Notice that the original "VisiCalc" is copy-protected.
