It's 36-bit oriented, but take a look here:

73, doug- who's programmed PDP-8's, 11's, 15's and DEC-20's.  Oh, yes,
Vaxen too.

   Hi Dave,
     As a retired Digital Equipment Corp. (DEC) employee I am very familiar 
   with the PDP-11 product line (as well as the PDP-8,10,12 and VAX).
     I don't know how much help it will be but there was (and I believe still 
   is) a computer museum in Mountain View, California that had a number of 
   PDP-11's as well as some PDP-8's and PDP-12's with peripherals such as tape 
   drives, external disk drives and card readers. I know there once was a very 
   good museum in Boston (they had a functional PDP-1) but it may have closed 
   when DEC was sold off to Compaq. I've also heard there was a DEC Museum in 
   Ottawa, Ontario, Canada but I don't know much about it.
     Regarding the Fortran and Cobol programming languages, I believe there are 
   freeware versions of both available for the windows PC. This wouldn't be 
   like using the punch card system we suffered through back in the day, but 
   they might give your students a feel for the structure of the older
