 Jerome Fine replies:

 YES!!
 *grins* (You just asked "Can you" - not to actually describe them!)

 Now, to actually describe them "all", I don't think it is worth while
 to spend all that amount ot time (a few centuries) or the space.  But,
 The major 3 are (there are many more):

 RSTS/E

 RSX-11 
Shoot, that one statement covers, what, 9 OS's?

...
  RT-11  
There are so MANY more than this!

For a partial list see the PDP-11 Emulation Webpage:
http://www.aracnet.com/~healyzh/pdp11emu.html

For a "complete" list see:
http://www.village.org/pdp-11/faq.pages/pdpOSes.html

Depending on how you count there is something like 20-34 different OS's.
