DR DOS 5.x

DR DOS is an MS-DOS compatible operating system from Digital Research that evolved from their earlier CP/M-86 based products Concurrent DOS and DOS Plus.



Release notes

Version "4" was skipped to avoid being associated with the disaster called IBM-PC DOS 4.0 and MS-DOS 4.0.

New features include ViewMAX, a GEM-based GUI file management shell, the BatteryMAX power management system, bundled disk-caching software, and HMA and UMB memory use that frees up conventional 640k.

Notice that this was released in May, 1990 well before MS-DOS 5.0. Microsoft was scrambling to get similar features in to MS-DOS 5.0, that they released in June 1991.
