The WG's make things a bit easier because they accept from 0-5V input
signals, so no amplification is needed.   Plus also they accept
composite sync... something I forgot to point out in my previous
notes.

The IIgs only puts out composite sync, so to use it with a Go7, you'd
need a sync splitter prior to the monitor.

Using a Wells Gardner K4900 or K7000 analog series instead of a Go7
would be the most elegant way to go... if I didn't want to learn about
op-amps or common base transistor configs.

I imagine it looked fine on a standard rez monitor for all modes
except 640x240... the rest would be akin to standard arcade game
resolutions..

Painful.   I see how huge these arcade game mobos are such as the 2
board set in my Zaxxon.  Easily the real estate of 4 Apple II mobos.
It's obvious Woz wasn't doing the board designs!
