<computer> An Intel 8080-based machine made by MITS. The Altair was the
first popular microcomputer kit.
It appeared on the cover of the January 1975 "Popular Electronics" magazine with
an article (probably) by Leslie Solomon. Leslie Solomon was an editor at Popular
Electronics who had a knack for spotting kits that would interest people and
make them buy the magazine. The Altair 8800 was one such. The MITS guys took the
prototype Altair to New York to show Solomon, but couldn't get it to work after
the flight. Nonetheless, he liked it, and it appeared on the cover as "The first
minicomputer in a kit."
Solomon's blessing was important enough that some MITS competitors named their
product the "SOL" to gain his favour. Some wags suggested SOL was actually an
abbreviation for the condition in which kit purchasers would find themselves.
Bill Gates and Paul Allen saw the article on the Altair 8800 in Popular
Electronics. They realized that the Altair, which was programmed via its binary
front panel needed a high level language. Legend has it that they called MITS
with the claim that they had a BASIC interpreter for the Altair. When MITS asked
them to demo it in Albuquerque, they wrote one on the plane. On arrival, they
entered the machine code via the front panel and demonstrated and sold their
"product." Thus was born "Altair BASIC."
The original Altair BASIC ran in less than 4K of RAM because a "loaded" Altair
had 4K memory. Since there was no operating system on the Altair, Altair BASIC
included what we now think of as BIOS. It was distributed on paper tape that
could be read on a Teletype. Later versions supported the 8K Altair and the 16K
diskette-based Altair (demonstrating that, even in the 1970s, Microsoft was
committed to software bloat). Altair BASIC was ported to the Motorola 6800 for
the Altair 680 machine, and to other 8080-based microcomputers produced by MITS'
PC-History.org Altair 8800 page.
