   Is the RSX AME still supported under 7.3?

   If so, then, yes, it may be possible to run a 40 year old binary
   on the latest VMS for VAX.

   But that depends on the definition of "run".  The AME added
   compatability mode emulation when the first VAXen without
   compatability mode shipped.  I'm fairly sure you could also get
   40 year old images to run on SIMH on just about any platform.

   So if I have SIMH simulating a PDP-11 on an Itanium, am I "running"
   40 year old images on the latest VMS for Itanium?

   Or do we require hardware execution of the instructions to at least
   the extent that VAX-11 series microcode implemented compatability
   mode instructions?
