IIgs to arcade monitor experiment

[MdntTrain <js@cimmeri.com>]

I'm my seemingly never-ending dallying with with IIgs video, I thought
I'd try interfacing my IIgs to an analog 15khz 19" RGB Electrohome
"Go7" arcade monitor I have here.. just to see how well it works (or
not).

I could use some insight on impedance matching and video signal level
from you resident masters of electron manipulation.  :-)

Here's the situation.

The IIgs video has these output specs:
  RGB:  1 Vpp @ 75 ohm impedance
  Sync:  4 Vpp @ 2k impedance

An arcade monitor (non VGA type) typically has these input specs:
  RGB: 4 Vpp @ 5k impedance
 Sync: 2 - 4 Vpp @ 35k impedance.

Video: these numbers don't look well matched, and I'm not sure what to
do about it yet.    If I connect the IIgs RGB directly to a higher
impedance than 75, the signal voltages are higher.. not as high as
4V... but maybe enough for sufficient contrast.   However, does the
IIgs video signal get screwed up somehow if I don't load it with 75
ohms?

Sync: looks like a better situation.. as the voltages start out in the
right range.   I'm not sure but my guess here is that the 35k sync
input impedance won't be a problem for signal integrity ... as either
2k or 35k are "high impedance" inputs.

Any thoughts are greatly appreciated as always.
