The PDP-8/e running at Living Computer Museum was originally put together by a
gent who was recreating the system on which he learned to program in high
school. When he was a sophomore and began programming on the system (running
TSS/8, inspired by Tops-10), there was a senior who was the de facto operator
by the name of Monte Davidoff. Monte has confirmed the story to me.

We restored an 8800 to running condition so that Paul Allen could recreate the
feel of loading a paper tape of the original BASIC (recovered from his own
DECtapes by yours truly). He compiled the 8080 simulator on our 2065, punched
the tape on an ASR-33, then loaded it into the 8800. (This was the 8800 and
Teletype used in the Leslie Stahl interview, part of which was filmed at the
museum.)
