No, according to <http://en.wikipedia.org/wiki/Pre-
emptive_multitasking#Systems_supporting_preemptive_multitasking> and 
<http://en.wikipedia.org/wiki/Unix>, Unix, at Bell Labs, was the first 
operating system to support *pre-emptive* _multi-tasking_, in 1969/1970 
(hence the Unix timestamp 0 equals 1970-01-01 00:00:00 UTC) as an 
improvement to the time-sharing Multics (1964) where multi-tasking was first 
implemented.  Sinclair QDOS (1984) and Amiga OS (1985) and other operating 
systems (particularly the Unix-like ones) followed Unix in that regard.

Sometimes, what you learn is wrong. If those wrong ideas are close to the 
root of the knowledge tree you build on a particular subject, pruning the 
bad branches can sometimes cause the whole tree to collapse.
