The PDP-8 was DEC's major breakthrough, and now considered the first successful minicomputer. It was, by a significant amount, the cheapest computer yet made at the time. The PDP-8 was constructed with discrete transistors, packaged into DEC's FLIP CHIP technology.
Operating Systems
The PDP-8 could run various operating systems including:
Emulators
There are various emulators for PDP-8 systems including:
| v • d • e PDP-8 Computers, Software and Peripherals |
