All this talk about BASIC and not one mention of FOCAL. Back in my PDP-8 days at university, BASIC was a pain because it was too big to fit into the 4k word memory and so it was split into two parts, I'm assuming the parser and the runtime, that had to be loaded separately from paper tape. FOCAL, on the other hand, was half the size and so you could easily load it in one go and get some coursework done in your allocated 1 hour slot.
But about this PDP-11 emulator, unless it comes with Adventure then I'm not interested.
