I am trying to split OS REV 11 into two 8Kb Eproms and install them in my 1200XL. The Eproms are 28 pin 2764s. I was hoping you might have some insight as to how to do this.
Try burning the first 2764 and see what the last 8 bytes are. Then you should be able to tell where to start burning the second one. This would be easy to do with my ProBurner.
