Abstract
The PDP-7/9 Communications Package was written to provide data transfers between the buffer controller (PDP-7 or PDP-9) of an ESL Display Console and a host computer via a 50-kilobit serial Dataphone link. Initially, only one of the displays (with a PDP-9 buffer controller) was to be operated remotely over q 50-kilobit line, and the only feasible access to the 7094 CTSS host computer was via the PDP-7 buffer controller of the other display, which is directly connected to CTSS channel D. For this connection, the PDP-7 could be looked upon as the "host" for the PDP-9, although it merely served as a message-handling intermediary for the real host, the 7094
Persistent DSpace Link
