Gould, not Harris

from above: 1988 Concurrent Computer Corporation merged with MbuttCOMP. 1985 Concurrent Computer Corporation spun off from the Perkin-Elmer Corporation. 1974 Datacraft acquired by Harris Corporation. 1973 Interdata acquired by the Perkin-Elmer Corporation. 1967 Harris Computer Systems founded as Datacraft. 1966 Concurrent founded as Interdata, Inc.

as undergraduate (late 60s) ... we reversed engineered ibm channel i-o interface and built a channel interface board (originally) for interdata-3 ... which was programmed to emulate a ibm telecommunication controller. lots of past posts mentioning the

later the project upgraded to a interdata-4 (w-channel interface board and programmed to emulate the ibm telecommunication controller) and several embedded interdata-3 processors dedicated to line-scanner function.

in the late 90s i ran into somebody that said they made an extremely good living in the early 80s selling the (by then perkin-elmer) boxes to nasa. the ibm mainframe channel board was still wire-wrap and he conjectured that it could have still been our original design and implementation done at the univ. nasa was apparently using the line-scanner for serial interfaces other than just terminals ... various kinds of data collection and other devices where the data was pbutted onto ibm mainframe.
