Re: Using IIgs with VGA monitor - how to go?

["Bill Garber" <willy46pa@comcast.net>]

There have been earlier discussions on that in the group,
one being a set of FAQs one called Monitors. I also have
been seeking a method of getting the proper sync between
the IIgs RGB signals and VGA. I have tried several types
of electronics so far and none are very good. Most times
I end up with zig-zags at the start or end of the screen. I
had once a perfect screen, but, there were 2 of the same
screen side by side on the same monitor. ;-) Well, I am not
about to give up now. I've found several chips that I believe
when used together properly will give me what we all seek.
I will for sure let everyone know when I get it. Believe it or
not, I will be able to offer it for much less than $50. Sorry
I have nothing positive for you, but there is plenty of info on
the web. I've been working on this for 2 months now, and
the only thing I have is hope and a prayer. Good Luck.
