@bjjones37 First off, on the A3K. Which Buster chip are you using? Have you tried all Zorro slots with the card?
The ROMs you pulled. When you put these back in, does the system work again?
From videos I have seen of Chris Edwards YT channel. I am under the impression the Revision 6 boards require something called a ROM tower. So simply just plugging in new ROMs without the tower part may not work.
