ROMP

The ROMP is a reduced instruction set computer (RISC) microprocessor designed by IBM in the late 1970s. It is also known as the Research OPD Miniprocessor (after the two IBM divisions that collaborated on its inception, IBM Research and the Office Products Division (OPD)) and 032.[1] The ROMP was originally developed for office equipment and small computers,[2] intended as a follow-on to the mid-1970s IBM OPD Mini Processor microprocessor,[citation needed] which was used in the IBM Office System/6 word-processing system. The first examples became available in 1981, and it was first used commercially in the IBM RT PC announced in January 1986. For a time, the RT PC was planned to be a personal computer, with ROMP replacing the Intel 8088 found in the IBM Personal Computer. However, the RT PC was later repositioned as an engineering and scientific workstation computer. A later CMOS version of the ROMP was first used in the coprocessor board for the IBM 6152 Academic System introduced in 1988, and it later appeared in some models of the RT PC.
