The software provides enhanced sounds I have never heard on a PE+ and the graphics is a higher resolution but if there is a error opening and closing the door does not clear the error.
I have to run a clear chip to clear any error, even a simple 3200 code.
The customer wanted me to make sure the boards were set for bill validator after the repairs, a busted diode one one, a bad RAM chip on another, a bad program socket on another. The 4th board had no problem I could find so I just re-seated everything, just in case.
On the first 3 I had to run the clear chip to get a good game.
None of my set chips would set the bill validator. Stepping through the test procedure told me the bill validator was already enabled. I assumed the special software dumped the set into the EEPROM upon power up.
So I sent the 4 boards back and the only one that still takes bills is the one I did not clear. But they all said the bill validator was enabled.
I explained to the customer that the boards were all set for BV in software. They are demanding a set chip.
I retained a copy of the bin's and will load them into a board tomorrow and see if those 8 DIP switches on the PE+ were utilized some how to enable features.
