PDP-11:

* PDP-11 (Programmed Data Processor-11) is one of the most famous computers in computing history, one of a series manufactured by Digital Equipment Corporation (DEC) from the early 1960s through the mid-1990s. PDP-11, which was sold in 1970 for $10,800, was the only 16-bit computer ever made by the company.

* The PDP-11 had a number of other features that distinguished it from most of its contemporaries, including multiple (eight) register s; multiple addressing models; a hardware stack ; processor error trap s; and a separate communications path for memory and peripherals (called the UNIBUS ) that could move data independently of the processor. Many early developers and users of the UNIX operating system ran it on the PDP-11 after the original Multics system was no longer available.

* Before the 1970s, computers were not thought to be something that the average person would buy or use. At about $1,000,000, they were prohibitively expensive. Furthermore, computers of the time were so large and complex that a computer center was required to house one and a sizable staff was required to look after it. To dissociate their product line from these public perceptions, DEC didn't refer to the PDP as a computer at all, but used its name, the Programmed Data Processor, as a generic term. DEC's first model, PDP-1 sold for $120,000 - about 40 times the price of a good computer today, but a bargain at the time.

The Pirates of Silicon Valley-summary

This highly interesting video informs us about the breathtaking steps made by Bill Gates, Steve Jobs, Steve Wozniak, Steve Anthony Ballmer and others in order to make a dent in the Universe or to create a new consciousness as Steve Jobs says.

Computers are the big passion for this group of young people and, as we know, Bill Gates is now the richest man in the world.

As the video is quite long, I’ve tried to summarize it and you can maybe only watch it in parts, according to your interests.
