Bill Gates - Before he was famous
From Basic to Microsoft
The Mind of a Programmer

 

It is difficult to imagine what the state of the personal computer industry would be without Microsoft. The machine that runs without a single item of Microsoft software is still comparitively uncommon. What might be more surprising is that this isn't a complete accident but the result of a careful strategy.

Bill Gates, the man who invented Microsoft, had a goal best summed up by "A computer on every desktop and Microsoft software in every computer". Yet it was by no means obvious that a company could survive, let alone grow, by doing nothing but selling software back in the early days of the personal computer - after all it wasn't even clear that there was a market for the hardware!

William Henry Gates III
(Born 1955)

Billionaires are always interesting but Gates is unusual in that he is a rich techie. The problem with discussing Bill Gates is because he is so rich (the richest man in the world in 2009 despite having given away $3.8 billion in the same year according to the Forbes list) and because Microsoft is so powerful a dispassionate account is hard to come by.

The legend is that somewhere, presumably in a garage, a couple of high school kids produced a version of Basic that ran on personal computers and the rest just happened. The truth is somewhat different.

Bill Gates had already set up a company, Traf-O-Data by the time he was 16 and was already making money from computing.

From math to computing

He didn't just happen to create a microcomputer Basic but set out to do so with the intention of making money. This isn't to say that he wasn't interested in computers, he was, and programming in particular. Math was certainly his strong subject although by all accounts he was bright enough to have made any subject his own.

Math is important because it shares with programming the same modes of thinking. The school that Bill Gates attended was far-sighted enough to provide the kids with time on a link to a PDP 10 - a minicomputer whose architecture helped form the minds of a generation of assembly language programmers. During lunch times Bill Gates learned to program. His first efforts were small - noughts and crosses - but eventually they grew to include a Basic interpreter for the machine - a very advanced piece of programming for a 13 year old!

It was in the computer room that Bill Gates met Paul Allen - the future co-founder of Microsoft. Together they talked computers and programmed. Bill Gates had an extra interest - making money out of his talent. Now you could see this as something almost twisted in one so young but there does seem to be an almost natural connection between computers and making money. It's almost as if you can only judge the success of what you do by what people will pay for it. They were paid to debug the operating system of the local PDP-10 timeshare, to computerize the school timetabling and they built a microprocessor based machine to work out traffic census data and offered a data-processing service to their local authorities. Traf-o-data was their first company and their fist money-making enterprise.

The race for Basic

Bill and Paul talked a lot about the future of computing and about forming a company to produce software. Their minds must have been more than prepared for the announcement of the first personal computer - the Altair. When it appeared on the cover of the January 1975 issue of Popular Computing both Bill and Paul realized that this was it - the future.

The Altair the machine that started it all

Bill phoned Ed Roberts whose company Micro Instrumentation and Telemetry Systems (MITS) produced the Altair kits and claimed to already have a version of Basic for the 8080 microprocessor and that he was ready to do business. The only part of the claim that was true was the part about being ready to do business. To produce the Basic, Paul Allen first had to write an 8080 simulator for the college PDP-10 - using a book bought from the corner bookshop, written by Adam Osborne, that gave the full 8080 instruction set!
