I will order the 877A and pull the 661.hex for me then. I am assuming "A" is better in this case.. Well, if I have to pay for shipping, I will be adding Atmel Tiny13's and 12F509's on there too. So a 877 and 877A is no big deal. But plan on using the A.
Another thought, a hand wired version, maybe that somehow is messing something up at 20Mhz with the "A" chip, maybe stray noise, slew or something. Just a thought.
