Interesting to hear that the grade of compatibility was that high. I've
neved had the chance to play with any 18-bitters.
You can indulge in 18-bit nostalgia courtesy of Bob Supnik. His Computer
History Simulation Project includes simulators for the DEC 18-bit computer
line. Check out http://simh.trailing-edge.com/ if you are interested.
Unfortunately, there isn't much surviving software for these machines. The
site does include a PDP-7 based simulator of the PDP-8(!), and the
"Advanced Software System" OS for the PDP-15 (which I believe will also run
on the PDP-9).
Bob's wish list includes a plea for DECsys and the First through Fourth
Editions of Unix, but unless someone unearths a cache somewhere, these may
be lost to history. Too bad. :-(
