Techknight, got it working!

Thanks for your urging to check into the address and data lines. Apparently, only the first 8 address lines are actually connected to the ASC. I took out the 68030 and checked for continuity on the address lines and saw that A6 was not making any contact.

I jumpered all of the address lines including A8:A11 and the machine wouldn't boot, so I began removing each of these until it booted. I had a feeling that there couldn't be 5 bad lines especially knowing that PlayerPro worked fine. 

Even the chime works and sounds right. No more hangs. Finally got this little SE/30 to working order!
