Wrong. The original IIgs mouse support (ROM 00 and ROM 01) was

specifically designed to allow the use of a IIe mouse card, so that a

IIe user upgrading to a IIgs could plug in their mouse card and

continue to use their mouse, rather than having to fork out money for

an ADB mouse.

In the ROM 00 and ROM 01, the ADB mouse is controlled by the slot 4

mouse firmware. If you disable this, then you lose all access to the

mouse, from GS/OS and ProDOS-8. However, if you install a IIe mouse

card (in any slot, as long as it is set to "Your Card"), then that

mouse can be used in all ProDOS-8 and GS/OS applications. (There may

be some programs which assume the IIgs mouse is always in slot 4, or

bypass the firmware and try to use the ADB mouse directly. These

programs would not work with a IIe mouse card.)

If the ROM 03 IIgs, Apple rewrote the mouse firmware. The ADB mouse

is controlled directly by the IIgs toolbox (Miscellaneous Toolset),

and the slot 4 mouse firmware uses the toolbox code. (The ROM 00/01

is the other way around - the toolbox calls use the slot firmware.)

This means that for a ROM 3, if you set slot 4 to "Your Card", you can

still use the mouse in GS/OS programs, but you cannot use it in

ProDOS-8 programs. I have my system set up this way.

If you install a IIe mouse card into a ROM 3, then that mouse will be

available to ProDOS-8 applications, provided they use the standard

firmware entry points (which are the same for the IIe card, the IIc
