The first annual customer satisfaction survey is taken.

RSTS-11, a timesharing operating system for the PDP-11, is introduced.

RSTS-11, in use here at Boston Telephone in 1975, was the first general purpose small computer operating system with generalized device handling. RSTS-11 was particularly well suited to commercial applications because of its sophisticated file handling and protection capabilities.

The DECsystem-10 is introduced, marking a change in the marketing philosophy of the PDP-10 group.

The entire DECsystem-10 line used the same basic monitor system to give users unequaled expansion capability. The first DECsystem-10s, the 10/40 and 10/50, used the proven KA10 processor which was developed for the PDP-10 in 1967.

The PDP-11/45, the most powerful PDP-11 family member to date is introduced. The PDP-11 was featured in Garry Trudeau's Doonesbury comic strip.

The PDP-11/45 was an excellent computational tool for large multi-user, multi-task installations. Through memory management, memory could be expanded to 128K, which included a combination of bi-polar and MOS memory. Other features included a greatly expanded floating point processor.

The RTM (PDP-16) is introduced.

The RTM (Register Transfer Module) began a new concept in small computers and digital controllers. Announced initially as the PDP-16, this series of printed circuit modules could be tailored to any application and made to operate with or without programs. In terms of cost, the RTM closed the gap between small logic modules and the smallest general purpose computer.
