Thanks Vince! Yes, that's definitely it. I've been staring at the somewhat
related Tektronix 4013 terminal emulator too, in a couple of parent
directories above. I need to do some more investigating to figure out how
the driver actually works, but it looks like both programs are very
dependent on the store mode of the oscilloscope. Based on what I see, there
is no massive buffer that the driver iterates through to keep things
refreshed, but I might be missing it.

Now I'm working on real VC8E integration into SimH to better tell how these
programs work. Anyone want to help? :)
