Something in the "early graphical" space that I think may be difficult or impossible to emulate: the Culler-Fried Online System. I think it was built around an IBM 360 and operated at one site (UCSB) late 1960s into 1970s with the goal of running a particular educational/research application programming environment, CHM has one of the dual keyboards, and I am not at all certain that software exists. Not so early to timesharing (late 1960s) but using storage scopes for graphical output terminals. Al has a couple manuals in <http://bitsavers.org/pdf/univOfCalSantaBarbara/>. So we can get some idea of what it was like. -Frank McConnell
