Concurrent DOS 4.x

Originally an optional module for Concurrent CP/M-86 3.1, this version of Digital Research's CP/M provided basic compatibility with PC-DOS in 1983. Simple DOS applications that did not require hardware access can be ran on this. A stripped down single tasking version was released as DOS Plus and later DR-DOS.
