PDP-7
The PDP-7 is a mini computer produced by Digital Equipment Corporation (DEC). Introduced in 1965, it was the first computer to use DEC's flip-chip technology. At $ 72,000 (the equivalent of about $ 580,000 today), this computer was very affordable for its processing power. The PDP-7 has a word length of 18 bits, the instruction set is similar to the processors PDP-4 and PDP-9.
In 1969, the computer scientist wrote Ken Thompson , the first Unix - system in assembly language for a PDP-7 processor, which then alluding to the operating system Multics jest Unics was called. It was to become the operating system for the space computer game Space Travel , which required graphics to show the movement of the planets.
A few PDP-7s are still in working order and there is a restoration project in the Norwegian capital, Oslo .

"He and I rewrote 'Space Travel' to run on this machine."
