No, it wasn't pronounced "Doctor DOS".
It was DR, as in Digital Research.
Anybody else use it? My favorite feature was its memory management of the "over 640K" memory into the High Memory Area - the first 64K of extended memory. I remember getting insane amounts of "free memory" from the available 640K, easily in the 620K range. I think it was Sidekick* - a TSR PIM, that made especially good use of DR DOS memory management, appearing to use almost ZERO conventional memory.
Even DR DOS 6.0, however, reported itself as "IBM PC DOS 3.31" for compatibility with programs that wouldn't recognize a "version 6" DOS.
