FS Game: Mortal combat1 board set

They both use the same sound board. The Y-Unit has a big black processor on the bottom next to a vertical chip. The T-Unit does not. That's the biggest glaring difference. The revisions aren't really that important I guess because only certain ones work with the difference boards. Thanks.
 
Looks to be the t unit.

i'm interested can you post a picture of the main PCB please so i can make sure it's a t-unit. Also do you have the 2 wire harnesses connecting the 2 boards ?
Thanks
