Okay, this has been bugging me for a while. Is it possible to access the RAM that's underneath the character ROM and register area at $D000-DFFF? Mapping The Commodore 64 hints that it is possible, but doesn't say exactly how to do it, and the only control I can see for this area is the I/O-ROM select in register $01. It's not vitally important, but it would be nice if this area were available for use. Anybody know the answer?
