How to Use an A2320

[midway]

The A2320 is supposed to be used with ECS or OCS Amigas only.
It displays all of these modes normally. That's including HAM interlaced (4096 colors)
 Its not a graphics card, doesn't matter how much buffer it has, it wont show up. What you see is Chip Ram. 512 KB for your Amiga 2000.

I had to borrow one from a friend, after that it worked fine with my TFT
