There are also some zeropage addresses whose you should keep intact (or restore when page in the ROM), especially when you use the built-in I/O routines. Too bad my "online" memory cheats me sometimes, one of these zp addresses is $A2. $AE is also useful for further I/O. I used this value in UWOL to decide to load game from tape or disk drive 8, 9, etc.
