PDOS [SEP] programming language
PDOS
PDOS is a discontinued multiuser multitasking operating system, written in assembly language developed in the early 1980s by the Eyring Research Institute for the Texas Instruments TMS9900 processor, and later ported to the Motorola 68000 processor. At the time its speed, accuracy and power made it ideal for process control. It was used in system development for education and industrial uses. Eyring also sold application programs (e.g. a statistics package) for the operating system.

The included operating system was the UCSD p-System. Many other operating systems were available including CP/M-68K, Idris, PDOS, HyperFORTH Plus, BOS, TRIPOS, Mirage, and MOSYS. Programming languages available included Pascal, Modula-2, C, FORTRAN77, BASIC, 68000 macro assembler, APL, LISP and Forth. 
The MC68000 CPU were introduced in 1979 by Motorola.
