I did an awful lot of coding looking at my //e's green-screen monitor.
I hooked two monitors up to a Y-cable -- one green-screen, the other
an Amdek color 1. The color 1 would _almost_ be readible in 80 column
mode with the chroma knob all the way off.

Except the best video mode on the GS was 640x200, and it had its
quirks. Way better than the Apple //e. The Mac always had better
vertical resolution (384 vs 200). Shortly after the GS came out, the
color Mac II with 640x480, 256 colors from a pallette of millions came
out.

Except there isn't much software supporting that video mode. Unless
it's just line-doubling the 640x200 to 640x400, with double-height
pixels.
