DOS Plus

Operating System

DOS Plus was the first operating system developed by the OEM Support Group of Digital Research in Newbury, Berkshire, first released in 1985. Version 1.0 combined CP/M-86 Plus with the PCMODE emulator from Concurrent PC DOS 4.11, an internationalized and bug-fixed version of Concurrent DOS 4.1 brought forward by Digital Research UK, while later 2.x releases were based on Concurrent PC DOS 5.0 instead; in the broader Digital Research product line, DOS Plus is an intermediate step between Concurrent CP/M-86 and DR-DOS.
