- While VMS probably has not run on a PDP-11, I have a PDP-11 which
- could be made to run something like VMS - it's an old 11/60, which with
- the WCS/UCS option (writable control store/user control store), allowed
- one to actually program one's own microcode. I imagine that given enough
- time, one could have it running VMS after a fashion.
- I don't have the time, though! ;-}
