VERSAdos is an operating system dating back to the early 1980s for use on the Motorola 68000[1] development system called the EXORmacs which featured the VERSAbus and an array of option cards. They were typically connected to CDC Phoenix disk drives running one to four 14-inch platters. The EXORmacs was used to emulate a 680xx processor in-circuit, speeding development of 680xx based systems. It also hosted several compilers and assemblers.

Overview
editVERSAdos was a real-time, multi-user operating system. It was the follow on product to the single user MDOS that ran the 6800 development system called the EXORciser.
Both systems features a harness with a CPU socket compatible connector.
A Modula 2 compiler was ported to VERSAdos.[2]
