I have an oscilloscope so maybe i can find out.
A lot of the LCD monitors that shipped with VGA inputs accept sync-on-green via the VGA port, but i have some doubts about them accepting the signal from something like this without some additional sync rate conversion. I might have some ancient doodads for that too, somewhere. I used to buy weirdware speculatively.
If i get my Plus up and running i will try and find out.
