What is the Apple IIgs? – AddOhms Live Clip

During a live stream, I was asked: “What is the Apple IIgs?” In this AddOhms Live Twitch Clip, I answer the question.

The Apple IIgs was the last of the highly successful Apple II line of computers. The “GS” stood for “graphics” and “sound.” Compared to previous Apple II computers, the IIgs was a fully 16-bit machine. When connected to its proprietary RGB monitor, it rendered a gorgeous display. Sadly, not much software took advantage of the improved graphics and sound capabilities. The IIgs was fully backward compatible with the older 8-bit line of Apple II computers. Its compatibility was so good that most IIgs users only used it in the compatibility mode.

How did the Apple IIgs achieve backward compatibility?

The IIgs contains an ASIC called the “MEGA-II.” (Which has nothing to do with the “Mega” Arduino boards.) It includes all of the individual logic chips from the original Apple II design as a single IC. Well, in addition to that IC you also need to add a CPU, RAM, and a ROM.

In my opinion, the Apple IIgs is best of the Apple IIs. In fact, of computers in that era, it is my overall favorite. When I got the IIgs, it replaced my previous pick: a Macintosh SE/30.
