I found "Moffett's Ghost" interesting as well because I am an electronics/computer nerd and such in the electronics manufacturing industry. I wonder how much the producers of the show knew about this stuff because although Apple 2 BASIC is not quite IBM or Motorola assembly language, which I suspect an avionics computer's operating system to be written in since it has to directly interface with hardware, Apple 2 BASIC, at a glance, seems to have more common terms (even if the meanings are not the same) with English like "HOME", "PRINT", "INVERSE" & "NORMAL". It is funny that she used the "List" command without any mistake, the computer gave her a syntax error, she returned 3 times and it executed the command.
However, I went back and examined that scene with the Compaq portable and the screen does appear to be on the left, so maybe you remember it wrong.   See 1 other reply
