Coffee Pot Control

Postby littlenasboy » Aug Wed 11, 2010 3:41 pm

I just purchased a replica i, and I'm anxiously waiting to build it.

I was thinking that I would use it to turn on a coffee pot after a user specified amount of time. How difficult would this be? Does the apple I keep track of clock ticks?

Would I have to divide down the 1Mhz clock and use it to trigger an interrupt which would call a routine to increment a register?

Is turning on and off an I/O line as simple as writing to a register?

I can easily build the rest of the circuit with some relays and opto-isolators.

Let me know if you have any ideas/suggestions!

Thanks

Hey, I'm not too sure how to go about doing this, but I'm sure it is very possible as the replica is a very modifiable kit!
Good idea you have, if you make any progress please keep us updated :)

I just purchased a MOS 6522 VIA chip which adds both parallel IO capability and timer functionality to 6502 systems. This should allow me to do everything I was interested in.

I'll keep you posted...
