Software and documents


Not many software for the Apple-1 exist. Apple Computer itself had only a few cassettes to offer. Today it is very comfortable to use music player instead of cassette player.
All software for Apple-1 can be found as sound files. You can record those files on tapes or use modern music player.

Zaltair prank

Zaltair Zaltair was a prank done by Steve Wozniak. Very young Adam Schoolsky (later an Apple employee) helped him to pull of it at the West Coast Computer Faire. Of course, the Zaltair was a non-existing computer.

Steve Wozniak loves jokes and pranks. At the First West Coast Computer Faire (1977) he had many copies of a handout advertising the fictional computer called Zaltair. Woz wrote, he had 20,000 copies. Only a few still exist. MITS, the company building the Altair, obviously didn't like this brochure very much.

Woz didn't told Steve Jobs about this prank. Woz wrote in an article for the 'Digital Deli', that he told Steve Jobs the whole story four or five years later at dinner. Woz gave Jobs maybe 6 or more years later a framed handout as a birthday gift.

Fun fact: If you take the first letter of every word in the fictional quote on the front page, you get 'Processor Technology'.
