06/03/04 update:

The C2 version (replacement die unit) will fix this bug but will be exactly the same as the current die otherwise. Expect shipments of the new version (C2)  to begin roughly at the beginning of September 2004. (Oh well, we had hoped for the new front end to be added to the chips, .... At least you can plan ahead and place your orders now... and get back to business) Our continued thanks to the good Dallas folks for their continued updates... We suggest software coders might want to alter their software to insure best operational abilities in all cases. There are a lot of B7's out there...
