DSN standard interface adapter and buffer assembly used in the Mark 3 data system
T. O. Anderson · The Deep Space Network · 1976
The DSN Standard Interface Adapter and Buffer Assembly (referred to as the 900/SIA) is used to effect interface compatibility between the Xerox data systems 920 computer (XDS 920) and the Mark 3 data system (MDS) processors. It sets forth the requirements based on the differences between the two systems. Operational characteristics and general design strategy are described, as well as certain efficient implementation techniques used. From a software standpoint, the transfer protocol is discussed to a level of detail sufficient for its operation.
