IBM 3790
The IBM 3790 Communications System was one of the first distributed computing platforms. The 3790 was developed by IBM's Data Processing Division (DPD) and announced in 1974. It preceded the IBM 8100, announced in 1979.
It was designed to be installed in branch offices, stores, subsidiaries, etc., and to be connected to the central host mainframe, using IBM Systems Network Architecture (SNA).
Although its successor's role in distributed data processing was said to be "a turning point in the general direction of worldwide computer development," the 3790 was described by Datamation in March 1979 as "less than successful."
IBM described it as "a programmable, operator oriented terminal system."
The 3790 supported
The base unit of the 3790 was the IBM 3791 programmable control unit, which was offered as a choice of:
Attached to the 3791 were:
The 3790 failed to achieve the success IBM intended, due to several issues. It had a complex programming language, The 3790 Macro Assembler, and the customers found it difficult to deploy applications on it. The Macro Assembler ran only on an IBM mainframe and then the compiled and linked object was moved to the 3790 for testing.
