@mucker:
So now all the comments have got me clearly confused, what is the cheapest way to fitting a graphics card
The *cheapest* way to add a graphics card is to buy any amiga-specific graphics card and put it into one of your Zorro slots. Dealers won't have these cards anymore, so you'll have to check eBay.
The Big Book of Amiga Hardware has a list of all Zorro-gfxcards ever released (you need to look for cards labeled "ZII" or "ZAS"):
http://www.amiga-hardware.com/gfxrtg.htmlYour particular Zorro-Board has a "Fast" mode - there's a special version of the Cybervision64/3D that supports that mode (this version was manufactured by DCE) - though this version might be hard to find. The Cybervision64/3D is a good card though, just like Spectrum and Picasso II(+) cards. The Picasso IV is excellent, but expensive.
You have to keep one thing in mind though: ZorroII is slooow. It's way better than AGA, but you shouldn't use very high resolutions or too much colours - the ZorroII bandwith is to small to handle that much traffic.
