DEC GT40
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: CPU: KD11-B (PDP-11/10) VT11 display processor, including bootstrap ROM (same modules as VT11, but instead of the four-slot backplane, this has a nine-slot backplane to include the CPU and memory) MM11-L 8K word core memory (MM11-K 4K word core memory on GT40-Bx models) DL11-E asynchronous line interface LK40 keyboard VR14-LC X-Y monitor (or -LD for 230 V) 375 light pen 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.
