Jon, Don't apologise for you mistake on my part. That's how we learn. And it will be a good piece of info for the future to know. Now, is the DATA EEPROM on ALL JW parts initialized to '00' and on OTP parts to 'FF'? Or is that true in this case only because of something you have done? If this is true for ALL cases, then why is one part initialized to one thing and another to something else? This seems strange to me. Anyway, glad you figured out the problem. Now the prototypes can be delivered as promised. Regards, Jim On Thu, 24 February 2000, Jon Petty wrote: > jim@jpes.com
