One of either my Dell or ViewSonic work with my Toby as long as I use a 10 switch adapter, but bluntly, the Toby is just about the worst video card you could have in your machine. I'd suggest as a minimum upgrading to a 4•8 or 8•24. They're still not accelerated, but they have better VGA support and can do higher resolutions and even 24 bit.
Given they're unaccelerated you should be able to get one for a good price, although eBay prices are a bit wonky at the moment (sellers can't tell the difference between a high resolution accelerated card and a card that only works with one model of triangular CRT, is unaccelerated and can only do 5 shades of brown.
