Re: Apple 2 gs monitor and compatibility with a pc

["Jason Whorton" <jason@microxl.com>]

Hi.  How do you connect a Genesis to the IIgs monitor?  How do you connect a
CoCo 3 to it?  I have a bunch of old video game systems and computers that I
plan to try to get all connected together somehow to my PC's ATI
All-In-Wonder Pro video card (no, I don't own a TV for anyone that has that
pop up in their head), but if I can get a few things hooked up to something
else, maybe that would relieve some congestion of cables.  I plan to hook up
maybe 25 computers and video game systems, so any help with the IIgs monitor
would be appreciated.

Thank you,
Jason Whorton
