I had the usual memory verification issue recently and i found out later that the culprit was the power from my serial adpater cable. The strange part is that it programs my 40x just fine, but none of my 08/08M chips. Has anyone else had this problem when trying to download a program. The strange part is that it can usually see the microchip, so the cable is working somewhat. Also, if i tap the run button quickly, it will download sometimes. Other times it will download and then cut off before the download is finished. Contacts are fine, and the circuit is the normal stuff.
