I don't see how pullups would affect this code and open inputs need time to
drift. As for the supply, I often use 2*AAA batteries to power things.
Never had any problems yet. Maybe my initial guesses weren't that good...I
think I'd begin looking at the incomplete erasing theory!

For interests sake - my Datarase II will erase the program memory of a '508
JW in about 4-5 mins, the ID codes and OscCal word in about 9-10 minutes
when I read the contents at 5V. By design, my programmer always checks at
2.5V (the min spec), though, and doesn't give an OK on a 'blank check'
until I get to 16-19 minutes. For this reason, I always give it 20 minutes+
(depends how busy I am... I'll have to make a PIC timer some day...).
