	Hmmm an apple ay. Well if you know how to program an apple ie apple //
then you have the ability to produce some wild pinball machine, that would
be original. The apple will perform all the task you require with ease.
If I were doing it, I would buy an apple clone Or original, remove the case
mount the motherboard and power supply in the pinball machine. Design a digital
input output card, consisting of a series of multiplexers, ie 6x74ls154.
The price of apples makes this project a reality, and with the flexibility
of programming, makes it truley custom.

	The apple will have to run solinoids and led displays. I would also
include a sound processor. A simple multivoice spu will cost about $20.
The card will have approx 64 digital outputs. If you wish to run solinoids
then you will require a darlington transistor and a diode. To run leds you will
require a similar set up, but a single IC will run and entire display.

	The apple will require inputs also. This can be done on the same card,]
using a.. say, 32 to 8 multiplxer, which is 2 74ls154. These will detect the 
ball when it rolls over silver trigger sections next to the soilnoids.

	This little project should provide you with heaps of fun for while.
If the machine is old, and not worth restoring, the go ahead do it.
