Hi,
I am trying to repair a R&S SMS signal generator and suspect the microcontroller had been replaced. It is a P8049AH that has a mask rom that would normally contain the software needed for the unit to function. If, as I suspect, the P8049 has been replaced with no mask rom code then the unit has no hope of working. I have several programmers but nothing that can read a P8049AH. I would be happy to post it to anyone in Australia to check for me if anyone is willing

Cheers
Richard
