Hi Alexis,

I am a bit out of the loop on this one and don¹t have access to the message
board to cover old ground. However, can you verify that you have a clock
signal present at pin 5 of IC35. You can do this with either an oscilloscope
or a logic probe. Experience has show that the PIO lines P25 and P24 are a
great source of trouble in this area because the tracks run back to the CPU
directly underneath where the battery used to be!

Cheers,
Andy
