This site is for people who wish to learn about the PDP-8 minicomputer and for current PDP-8 users to get more information on these machines. The PDP-8 was an important early mini-computer in the history of computing and many are still running today performing their original function. The PDP-8 was used for industrial control, controlling experiments, running businesses, word processing, and many other uses.
This site is a work in progress so please make comments or request what you would like to see. At the bottom of most pages is a link to contact me. I have been concentrating on the ability to run a PDP8 over the web. I think that is working pretty well. If you haven't ever run a PDP8 especially if you haven't used command line operating systems the online documentation may not be sufficient to operate it like a pro but I have made it easy to play some of the games.
Various bits on this site are from Douglas W. Jones FAQ's The PDP-8 family of minicomputers were built by Digital Equipment Corporation (DEC) between 1965 and 1990. It was the follow-on to the PDP-5 computer with some instruction set changes. By late 1973, the PDP-8 family was the best-selling computer in the world. The PDP-8 has been described as the model-T of the computer industry because it was the first computer to be mass-produced at a cost that just about anyone could afford (at least with company money).
The PDP-8 is a 12-bit single accumulator machine that can address up to 32K 12 bit words. It has 8 basic instructions and the PDP-8/E executes them in 1.2 microseconds for simple instructions to 4 microseconds for complex memory reference instructions. This gives the machine about a .5 MIPS rating. Although the computer is very slow and memory limited by today's standards it was quite capable in its time.
Since the PDP-8 was a more personal machine than the larger more expensive machines, it was popular for playing with and various games were either written for it or ported to it from even earlier machines. More game information.
People also wrote programs to play sound on the pdp8. The pdp8 didn't require a fancy sound card, only an AM radio. Sound information and samples.
