Following up to an older post re what monitors can be used with the
IIgs, I recently ordered an RGB to VGA converter from this place in
Australia:
http://www.converters.tv/products/converters/rgb_converters/41.html
This item performs the conversion from 15.75khz / 60hz to 31.5khz / 60
hz, as well as the RGB to RGBHV.
It has arrived and I'll report back here how it works. I'm awaiting a
DB-15 connector and 5v power supply from Jameco. Testing will be done
with an early IBM VGA 31khz CRT monitor 6112.
