The first meeting of the legendary 
Homebrew Computer Club was held in 
Silicon Valley. Its first meeting in March 
1975 was held in one of its members' garage in 
Menlo Park in 
Santa Clara County. The Homebrew members were hobbyists, but most of them had an 
electronic engineering or 
programming background. They came to the meetings to talk about the 
Altair and other technical topics, and to exchange schematics and programming tips.  From its ranks came the founders of many 
microcomputer companies - for example 
Bob Marsh[?], 
Adam Osborne, or 
Steve Jobs and 
Steve Wozniak—the famous 
Apple founders.
Soon after this first homebrew computer club, other hobby compluter clubs emerged located all over the world.
In the Netherlands a homebrew computer club emerged with members meeting near the town of Utrecht. The HCC (Hobby Computer Club) as it is called still exists, has tens of thousands of members and publishes a magazine.
