System architecture for the Terminal Support Processor TSP system is now complete. The principal element in the system is a dual processor version of the Digital Scientific Corporation Meta 4 microprogrammed computer. Main memory magnetic core consists of 8 banks of 8K 16-bit words. Secondary memory is provided by a one-million-word Digital Development Corporation disk having a 495-kHz transfer rate and an average access time of 8.7 msec. The TSP is connected via an Interface Message Processor IMP to the ARPA computer network and other Lincoln Laboratory computers. Consoles consist of a keyboard, a small number of visual and audible indicators, a graphic input tablet, and a pair of storage scopes. Displays are driven from a shared vector and character generator which is now complete and being tested. An extensive character set includes most of the commonly used sets. A low cost input tablet has been developed utilizing a resistive sheet as the writing surface and an ordinary pencil as a pickup stylus.
