No Worries. I actually had a fair bit more to write, 10,000 character limit is cumbersome to work with. I"m currently reading over things, trying to shorten sentences in attempts to fit more in. Would prefer to keep it all as one single post.

Its quite simple for me

I haven't seen Mister_e's keypad routine. Anyone have the link handy?

Notes & Eratta:
First paragraph under schematic I state: Also, it's worth while noting that the 4MHz crystal isn't critical, you could if you wish use an RC oscillator. You'll save a few bucks. <hr/>*This assumes that you won't be connecting the keypad to the serial port. A crystal is mandatory if you intend to build the project entirely as presented.
