I don't understand why he got rid of the clock coincell i the rev 2c. Nice added feature to have.

Cost saving? Supplier ran out of stock and he didn't have time to order somewhere else? Shipping parcel lost en route?

Yeah most likely it is cost saving, 1x 144n diode, 1x 300ohm resistor, and a coincell holder is about $2. And you save on having less traces on board production. Also every trap door expansion has a battery and I have never seen a 500 without an a501 clone.
