As you know, one picture is worth a few thousand numbers.\
|
||||
As you may not know, Apple Business Graphics software can generate more types of pictures, in more colours, using more data than any other graphics package... On the monitor of your choice. And on virtually any printer or plotter on the market...

text: Steve Wozniak said that the reason the apple /// was so utterly horrible was because it was designed by the marketing people rather than the engineers. He said that the engineers were forced to put in EXTRA chips in the computer to DISABLE the extra memory! It crashed, and was just junk. I am amazed at how expensive these crap-balls are on Ebay.

Jobs leave apple in 1985, 2 years after the apple III\
|
||||
it''s true that Jobs wanted a silent computer (15 years in advance), whence the overheating\
|
||||
but it''s not the only cause of the failure

text: I've read that the case design and consequent overheating problems was at the direct insistence of Steve Jobs, who didn't like the noise of a cooling fan, and didn't want to sully the clean aesthetics of the case by adding ventilation slots.

text: I had an Apple III at work in 1984. I wrote some programs in Basic to automate some office processes. Ours had a 5MB Profile hard drive that sat between the base unit and the monitor. It also had a CPM card (Presumably with a Z80 processor) but we had no disks for it. Unfortunately I left the job before it was disposed of. We had a Superbrain before it and I wish I had gotten hold of that!

The Apple /// was designed to be a business machine. It was partly compatible with the [Apple II](/museum/apple-ii/) (thanks to a few options in the operating system). It used a powerful memory management system and worked under **SOS** (Sophisticated Operating System) which was a great, device -independent, operating system. This OS was the "ancestor" of **ProDOS** (the "professional" Apple operating system) and some parts of this system were used later in the [Lisa](/museum/apple-lisa-lisa-2-mac-xl/) and [Macintosh](/museum/apple-macintosh/) OSs.
|
||||
|
||||
Despite its unique features, the Apple /// had a lot of technical problems, namely, the horrible case design. It caused the internal temperature to get so hot that the motherboard would warp and some of the socketed chips would become unseated. To remedy this, Apple told people to literally pick up the computer several centimeters off the desk and drop it! It was a miserable flop in the marketplace.
|
||||
|
||||
The Apple /// was followed in december 1983 by the Apple /// plus which had an [Apple IIe](/museum/apple-iie/) style keyboard and a new video interface. Four months later, it was discontinued.
