027- How do I write programs which use the mouse?
The assembly language interface to the mouse firmware is documented in the
reference material that was supplied with the IIe AppleMouse card, the IIc
Technical Reference Manual, and the IIgs Firmware Reference Manual.
For a 'how to' discussion, see FAQs Resource file R034MOUSEPRG.TXT.

028- My IIe has a bad keyboard encoder IC. Where can I
get a replacement?
The AY-5-3600 PRO keyboard encoder is not easy to find, but it can be
replaced by the KR-9600-PRO keyboard encoder. The 9600 IC has more features,
such as the bounce fix. I have installed one in my IIe and it works fine.

029- Can I use an Apple III joystick on my Apple II?
No. The Apple III joystick port has very little in common with the Apple II
one. The Apple III joystick's internal circuit arrangement and plug pinout are
very different from that for an Apple II joystick.
Do not attempt to connect an Apple II joystick to an Apple III, or vice
versa. At the very least, it will not work. At worst, you could damage the
computer. Here are the joystick port pinouts, for comparison:
II III
1 SW1 GND
2 +5V +5V
3 GND GND
4 PDL2 Joy-X
5 PDL0 SW0
6 SW2 +12V
7 SW0 GND
