VGA accepts analog signals of Red, Green, Blue plus Horizontal and Vertical Sync. The RGB out of the TS2068, as I was told is digital.

I could be mistaken but I believe the 2068 signals are analog.

Well, if the signals are analog, than you would figure that you could just hook the VGA monitor up... except that a VGA monitor is 31Khz (and higher). I think that the TS2068 would need a monitor that syncs down to, probably, about 15Khz. Anyone know for sure?
I was talking about this similar subject in the past couple of months, but not to hook up to a VGA monitor, but rather to hook up to an RGB monitor (in my case, an Amiga monitor).

The TS2068 produces a 15KHz video signal (the exact details are in the
technical manual).
My TS is modified to have CGA output directly from the unit, and
without a scan doubler of some sort you won't be able to drive a VGA
monitor that cannot sync below 30KHz (i.e. all of them these days).
European PAL TVs have RGB inputs that take 15KHz inputs, I don't know
if any US NTSC TVs have similar inputs that could be used?

Do you have these modification (circuit or schematics)?
[My TS is modified to have CGA output directly from the unit, and without a scan doubler of some sort you won't be able to drive a VGA monitor that cannot sync below 30KHz (i.e. all of them these days).]
So that I can Reply it in my TS2068? So that I can search for a CGA monitor...
Thanks.
