I'd like to know what functions are performed by the 6522 chip.
I assume it is a PIA, with two 8-bit bi-directional (programmable0
parallel ports.  But what else does it have? Interrupts, timer,
or what?  The 6530 chip used in KIM-I had all that plus ROM and
a little RAM.  Are there any manufacturer's spec sheets for
this and other 6502 family parts, or do I need to borrow a
Commodore or Apple manual?
	Thanks, mike k
