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!

I had a go at building this

would convert it to VGA, but no luck.
Any ideas?
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.
