The PDP-10 (Programmed Data Processor model 10) was a computer that made timesharing real. It was adopted in the mid-1970s by many university computing facilities and research labs, including the MITAI Lab, Stanford, and CMU. The
PDP-10 was eventually eclipsed by the VAX machines (descendants of the PDP-11) when DEC recognised that the 10 and VAX product lines were competing with each other and decided to concentrate its software development effort on the more profitable VAX. The PDP-10 was finally dropped from DEC's line in 1983, following the failure of the JupiterProject at DEC to build a viable new model. Research PDP-10
