Thanks to a tip James Littlejohn gave me I purchased a 15Khz RGB CGA
YUV Component Video YCbCr to VGA Converter Scaler from
http://www.ambery.com/rgbcgatovgac.html
Wiring up the cabe was quite easy:
IIGS VGA 15 pin
Pin 1 Gnd --------> Pin 5 Gnd
Pin 2 Red --------> Pin 1 Red
Pin 3 CSYNC ---> Pin 13 HSYNC / CSYNC
Pin 5 Grn ---------> Pin 2 Grn
Pin 9 Blu ---------> Pin 3 Blu
I posted pictures of the video output on my Picasa albums:

It looks like 640x400 dithered doesn't come out to well...
