DEC GT40 is a VT11 vector graphic terminal and general-purpose computer produced by the Digital Equipment Corporation, first introduced in October, 1972 (selling for “under $11,000”).

Description

The DEC GT40 consists of: Because the GT40 contained a PDP-11 class computer, the terminal could also serve as a computer in its own right, IEEE Computer wrote: The GT40 may be used either as a stand-alone graphics system or as a remote terminal interacting with various types of host computers. John Mucci, marketing manager for the DEC graphic-11 group, sees the GT40 being particularly useful in the areas of graphic research, design, engineering, architecture business information systems and many other uses needing a fast, low-cost graphics display. In a stand-alone configuration, the PDP-11/10 within the terminal can be expanded with additional memory and any PDP-11 family peripheral to build as complex a system as necessary. “In fact, the central processor used in the GT-40 can be any PDP-11 family processor,” says Mucci, ”since the display processor is interfaced via the PDP-11's Unibus.”
