Summary of my experience with VGA monitors on the Mac LC after
constructing LC -> VGA adaptor:

- NEC Multisync 2A 
	-Works well with VGA output.

- "Clone" VGA color
	- Does not work. There is some kind of image, but it is jumping
          all over the screen in a random fashion (looks like PAY TV
          without a descrambler).

- "Clone" VGA Monochrome monitor
	- BAD ghosting (1/4" almost) everywhere.  The monitor no longer
          works on a PC.  Basically, the LC seems to have blown the
          monitor somehow (only slightly skewed horizontal lines that
          move up and down remain when plugged to a PC).

Basically, the output only seems to work with GOOD monitors and can
result in the destruction of really cheapo ones.  I haven't looked
into the destruction yet, but it looks just like a TTL monitor with the
horizontal sync busted. 

I'd like to hear from other people who have attempted this too!
