Yes, that was discussed elsewhere in the thread. Don't know how this got
into two mailing list, only started with my original post to one. It's also
outside the late 60s scope I was asking about.
Just for clarification, The Cineamtronics/Vectorbeam version is not done
entirely with TTL logic. It's comprised of a
TTL based psuedo incarnation of a PDP-8 instruction set (a TTL based PDP-8
simulator if you will) that in turn is running the actual software for the
PDP-8 version of Spacewar, which Rosenthal licesned from MIT.
