Hello,

I have made a new 340 display program.  Unlike previous display hacks which compute a new point and then display it immediately, this one computes a complete dispay list in advance.  I think it can serve as a good example of how to use a display list, which is how most 340 programs work.  It works both in timesharing using the .DSTART UUO, and out of timesharing using IOT instructions and interrupts.


The program was inspired by this photo.  It looks like it was taken off the 340 display.
