What the icons meant?




Last Apple II line computer developed by Apple, totally compatible with it, last computer developed by Steve Wozniack, some units were launched in a special edition (Apple IIgs Special Edition) with Steve Wozniack signature in the case.

The CPU, Western Design Center 65SC816, is a 16 bits chip totally compatible with the MOS 6502, software developed for Apple II is compatible with Apple IIgs.

It was the first personal computer with a LSI (Large Scale Integration) chip built in, it was called IWM (Integrated Wozniack Machine) and it replaced a galore of chips in the mother board.

The sound chip, Ensoniq 5503 Digital Oscillator, was the best sound chip found in any computer for a long time, better than sound chips found in Macintosh or Amiga.

The gs mean graphic station, either the graphics quality isn´t better than Apple IIe and even worse than Amiga graphics.

This computer wasn´t distributed in Spain, only in United States and there it was a great success, compete in sales with Atari and Amiga 16 bits computers.
