QDOS    
The Sinclair {QL}'s proprietary {operating
system}. The origin of the name is uncertain (a weak pun on
kudos, perhaps, as {Unix} was on {Multics}). There was
another OS around from the birth of personal computers called
Q.D.O.S. - Quick And Dirty Operating System. QDOS might also
stand for QL Data/Disk/Drive/Device Operating System.

QDOS did the usual OS sorts of things, as well as
multitasking. It was unusual in several ways. It treated all
devices (serial ports, mouse ports, screen, {microdrive},
{disk drive}, keyboard, etc.) uniformly, so you could print a
text file direct to disk or save a binary to the screen for
example.

Also logical channels could be assigned to particular physical
devices. Output directed to a channel would go to the
appropriate in/output. This also meant you could have many
windows on screen (the QL booted up from internal ROMs with 3
windows - command line, output and program listing) all
independent to some extent. Channels could be redirected
without affecting the way the process sent or received the
data.
