The PDP-8 (Programmed Data Processor-8) was the world's first minicomputer. It was priced at the amazingly low price of $20,000.00. It was a 12-bit machine with a tiny instruction set.
The PDP-8 was DEC's first widely successful computer; the first successful "personal computer". Many PDP-8s were purchased by schools, university departments, and research laboratories. Later models were also used in the DECmate word processor and the VT-78 workstation.
