Mark,

Thank you for looking it over.  I've attached the files so you can start playing around with it in Eagle.  Presumably the goal for this is to produce a PCB that others can easily duplicate (i.e. a group project).  A couple of questions:

1) you mentioned that Q3 is a A1015 transistor.  The pinout is different (ECB vs EBC) than the 2N3906 and the A1015 is not in the symbol library.  Do you want to keep it as a 3906 as I have it so that people will not have difficulty finding that part?

2) again note the orientation of the connectors.  I flipped AN1 in the schematic to match the way you have it on your board.  I am not sure if orientation of others are critical or is it just a matter of getting used to the way it is.

3) Datasheet recommends EEPROM address lines to ground and not left floating, so I grounded them.
