Alternative Monitor for VAXmate

I have a Viewsonic VA912 which has worked well for me before in other
circumstances, but doesn't go down to 26KHz. I can't find a VP150 on ebay or
amazon at the moment, but I will keep a look out and see if there are any
others with a lower horizontal frequency too. Looks like a VX715 might do
the trick and I have found one of those!

As it looks like I am not going to be able to repair the monitor board for
my VAXmate I am wondering if I can do anything with the outputs from the I/O
board to drive an external monitor instead.
I had a go at building this
adapter.jpg feeding its output to a composite to VGA device to see if it
would convert it to VGA, but no luck.
For starters, try a Viewsonic VP-150. Syncs horizontally from 24-61khz. I
use these or a
few other monitors for syncing to odd DEC or HP systems.
