Yes, I actually always had it working in the past but while moving and restoring the game I broke a pin on the U4 chip. Now all of the SARK character's dialog is missing. I am trying to restore that part of the game sounds. I'm kind of a novice so burning chips is beyond my capabilities for now.
Sorry for the response delay. My ISP has been down. The chips are for the original arcade game. The U3 and U4 chips are 2532JL-45 The U5 is 2532JL-35. I will send you an image of the the chips on the board. The U4 is the damaged chip I must to replace. I would also like to purchase a back up set...
I have an EDOT and am in dire need of a replacement U4 ROM chip for the Squawk and Talk Board. I would gladly compensate someone for the chip and I also have some spare EDOT parts available if anyone is interested.
