So for those that don't know! there is a dmd power upgrade due to the large dmd having power issues on 4 Sega's that came out with this size screen. I got my machine working after a dmd power loss due to less than 5 volt supply issues, got a replacement upgrade lead from Pinball life which was a bit faulty when delivered, though really if you have the tools you could make your own.
Since I had to send my power supply board to Beaky, I sent the cable and he made some changes and improvements so working sweet now.
Attachment is of the Sega bulletin for power supply upgrade - not really a mod to "look at" but a mod to improve the performance if you machine resets or screen blanks out.
