6805 equipment pulls

I recall there were some 68xx parts offered to us in the early 80s by Motorola. They decided they didn't want to take a bloodbath on excess quantities of rom parts which did not meet specs or were refused by the original customer. They presented it to us as the rom was there, and you could add the external eprom, etc. and the rom would not affect you. I don't recall if they related how they were able to disable the rom, maybe a jumper that was bonded out to some pad with different options depending on whether they wanted the rom emabled or not. I think it was too early for the laser zapps the die method to be feasible, and certainly not in quantity. We were using 6802's and were evaluating using the 6802, 6809, or this sort of part for a higher quantity controller product we were working on. Eventually had to go with the 6809, rather than the lower power 68xx parts. Jim On 3/3/2011 5:53 AM, Eric Smith wrote:
