'''Note''' - Port DFxxh is the standard [[Upper ROM Bank Number]] register, which is also used by [[AMSDOS]], for example. Reserved banks are 00h=Basic, and 07h=AMSDOS. Bank FFh (and XFh) can be also considred as reserved (as it's used by the "128K RAM detection" in CP/M+). Other bank numbers can be used by one (or more) Schneiderware Pseudo ROM board(s).
