The PDP-1 (Programmed Data Processor-1) was the first computer in Digital Equipment Corporation's PDP series and was first produced in 1960. It is famous for being the computer most important in the creation of hacker culture, at MIT, BBN and elsewhere. The PDP-1 was also the original hardware for playing history's first computerized video game, Steve Russell's Spacewar!.
It has an 18-bit word and had 4 kilowords as standard main memory (equivalent to 9 kilobytes, or 9,000 bytes), upgradable to 64 kilowords (144 KB). The magnetic core memory's cycle time was 5 microseconds (corresponding very roughly to a "clock speed" of 200 kilohertz; consequently most arithmetic instructions took 10 microseconds (100,000 operations per second) because they had two memory cycles: one for the instruction, one for the operand data fetch. Signed numbers were represented in one's complement.
The PDP-1 was built mostly of DEC 1000-series System Building Blocks, using Micro-Alloy and Micro-Alloy-Diffused...
