Such ideas were popular in British computer academia at the time and later were adopted by some US designs such as the Intel 8086.

Distinctive features of the processor were memory-mapped I/O and an early version of segmented memory (similar to the later Intel 8086 but having both base and limit).
The Intel 80130, referred to as an "Operating System Processor," was developed as a support chip for the 8086/8088 processors and the Intel iRMX86 operating system.
It required a memory management unit (MMU) to support memory protection, so was not compatible with 8086 and 8088 processors.
However, if used on any 8088/8086 computers, or on some 80286 computers, the QBasic program may run very slowly, or perhaps not at all, due to DOS memory size limits.

Originally the peripheral processors were to be Intel 8086, but those proved inadequate and the system was introduced with Motorola 68000 series processors.
TRIPOS was ported to a number of machines, including the Data General Nova 2, the Computer Automation LSI4, Motorola 68000 and Intel 8086- based hardware.
