PDP-10

(computer)Programmed Data Processor model 10.

The series of mainframes from DEC that made time-sharingreal. It looms large in hacker folklore because of itsadoption in the mid-1970s by many university computingfacilities and research labs, including the MIT AI Lab,Stanford, and CMU. Some aspects of the instruction set(most notably the bit-field instructions) are still consideredunsurpassed.

The PDP-10 was eventually eclipsed by the VAX machines(descendants of the PDP-11) when DEC recognised that thePDP-10 and VAX product lines were competing with each otherand decided to concentrate its software development effort onthe more profitable VAX. The machine was finally dropped fromDEC's line in 1983, following the failure of the JupiterProject at DEC to build a viable new model. (Some attempts byother companies to market clones came to nothing; see Foonlyand Mars.) This event spelled the doom of ITS and thetechnical cultures that had spawned the original Jargon File, but by mid-1991 it had become something of a badge ofhonourable old-timerhood among hackers to have cut one's teethon a PDP-10.
