Most of us just use #7 & #8 for unlocked jurisdictions, to change games, mains, graphics etc. etc. Worth a try. Richard # 1 Autoplay # 2 Ignore Checksum # 3 Show State Status # 4 Host Override # 5 Printer/Hopper Overide # 6 Watchdog Overide # 7 EEPROM Clear # 8 Ram clear (tm here) If all goes well you shoud be able to make your choices(buttons or touch screen), before turning key for next choice.

(See attached picture.) A normal full SafeRam clear will not affect it. If you have locked your jurisdiction, you have two choices: 1. If you own an EPROM burner, you can simply pull the chip and erase it electrically, using the burner's electrical erase command*. This takes just a fraction of a second. These chips don't have a UV window, so an EPROM UV eraser won't work or be needed here. Once you've erased the chip, simply turn on SW1 switches 7 & 8, put the clear chip in P10, power up, and perform a full clear. You'll be able to choose a new jurisdiction during the setup. Note: Once you've cleared the EEPROM, the machine will not boot in normal mode and you will get a BSOD. This is normal. Just setup the clear and complete it. 2. Buy a "deep blue" clear chip from Jim (Blueridge slots) to clear the jurisdiction. This "special" clear chip resets the data in the above chip. Personally, I recommend option 1, even if you don't already own a burner, because you will then be able to use the EPROM burner to back up all of your game chips, mains, and graphics. Of course, if you don't already own a burner, option 2 is less expensive in the short-term, but short sighted IMHO. *When setting up the burner, choose chip 96C56B (16 bit) no matter what the last letter displayed on the chip is. We have since confirmed that erasing the chip allows a successful full clear and jurisdiction reset. Here is a picture of the chip in question.

How do I find Jim at Blueridge slots
I,m thinking if I can find a 93C56N eprom I could switch it out. Anyone know where I can get one?
