Well done! Glad you got it working!

The A2000 doesn't like mixed type of RAM within its bank, and you'd be mixing Static Column RAM with Page Mode RAM.

An A2000 doesn't care. Agnus always accesses RAM in the same way. It doesn't matter which type you use because it doesn't use the special features of Static Column RAM.
