Was the A2320 available some time before the A3000 was released or did it arrive after?
Is all the circuitry identical to what is on the A3000's motherboard?
I know intric8 is a purist when it comes to Amigas
so I do not expect you to use the card with an LCD. I wonder how good it will do with a modern LCD display, though.
When I last had my A3000, I had an RTG card installed connected to an old Dell 17" 4:3 LCD. I do not believe I ever tested the built-in display enhancer with an LCD. Before my RTG card, I was using an NEC 3D CRT. That was a nice monitor. Too bad it kicked the bucket.
