Hi there,

The Solution 880 (REV F 3/98) alarm panel PCB has a 64 pin QFP Microcontroller labelled as U6 and the identifying markings have been ground away. I would like to know the Manufacturer and Model of U6 so I have been searching through pinouts of various microcontrollers (circa 1998) for sometime now but still haven't been able to identify it. Is it possible one of the forum readers already knows this? as I would really appreciate knowing too!

Your kind help would be greatly appreciated.
Bruce

P.S If there are any Circuit Diagrams for the PCB in the wild, a copy would be nice too......
