Hi Aaron,
yep, the 7749 has been so picked apart, that pratically
every byte in the chip is accounted for. I forget the reason,
but I read somewhere that it won't go to 7,000 rpm.. I think
6,750 or there abouts was the limit.. Anyone know about this?
Anyway, the PromGrammer software (big, slow, Java thing)
for the Syclone Typhoon V^ works for the turbo sunbird chip too..
Offsets are the same...
