SMSQ/E

SMSQ/E is a computer operating system originally developed in France by Tony Tebby, the designer of the original QDOS operating system for the Sinclair QL personal computer. It began life as SMSQ, a QDOS compatible version of SMS2 intended for the Miracle Systems QXL emulator card for PCs, and was later developed into an extended version, SMSQ/E, for the Atari ST. Other contributors to its development include Wolfgang Lenerz and Marcel Kilgus.
