There's a reserved area in the AUX language card for RAM drivers, which is easily avoided, but if there's code executing here, it can potentially trash the zero page. I use this driver a lot, so I'm investigating it now. Will let everyone know.
A number of Aux RAM drivers copy themselves into all banks, so that they can switch banks with impunity while executing. Most such drivers (if you plan to allow one to be used with your compiler) allow you to lock out one or more banks for your own purposes. -michael Parallel computing for 8-bit Apple II's!
