The DEC GT62 is a dynamic refresh graphics terminal system with local processing introduced in November, 1975 at a price of $47,500. The GT62 is a combination of a PDP-11/10 minicomputer, a free-standing ASCII keyboard, provisions for communications links and the VS60 display subsystem. The VS60 display subsystem was also made available for other PDP-11 minicomputers at a price of $38,800.

In February, 1977 the GT62 was upgraded by replacing the PDP-11/10 processor with a PDP-11/34 with 16K words of MOS memory, ROM bootstrap and real-time clock. A dual floppy disk unit is provided for diagnostics as well as stand-alone operation. The upgraded GT62 can drive two independent CRTs and was listed at a price of $55,000.
