How successful?

Sold very well, probably around half a million in total. The Apple II and its direct derivatives remained in production until 1992.


There had been an Apple I, of which about 175 had been sold at $666.66 each, but it was supplied as a bare board without even a keyboard:

As the successor to Apple's first computer, the model II added the graphics and sound missing from the original.
The Apple II could be connected to a domestic television and use a cassette recorder for storage, or a matching monitor (as illustrated above) and floppy disc drives were available.
Later the models II+ and IIe added floating point BASIC and up to 64 KB RAM as standard.
The Apple II's styling was designed to make it look like a friendly domestic appliance rather than a complicated piece of hardware.
However it was also popular as a business machine and in 1979 the first ever spreadsheet program, Visicalc, was released for the Apple II.
