Well, i managed to install (right or wrong remains to be seen) MK ultimate in my MKII cab.
Swapped over an entire control panel and box that someone else had already drilled a hole in so i didn't have to molest my original.
Both run buttons work. Some buttons didn't show continuity when depressed and didn't work, so i swapped out the micro switches with some off the orignal board and are good now.
But when starting up i get the cmos u49 chip error.
Says can't restore factory settings.
Now the machine appears to play fine, i think the issue is memory.
None of the stores i had time to stop at today had the exact battery, but i tried the one that came on the board and the one from the MKII board.
I tested both and used the one that was better and had 2.9xx volts, which i figure should be plenty.
No change.
The u49 chip is soldered.
Here are my install pics, i have messed with dip switches as suggested in other posts during my million internet searches, but doesn't seem to change anything.
Also note that the bottom white connector i didn't connect anything to, the connect on the existing harness has at least one less pin and i figured better safe than sorry.
My biggest concern is that the volume doesn't stay where i set it, basically it runs full tilt. As soon as i press a button to select the lowest volume (which it does fine) at the next screen it reverts right back.
I left the sister board in from MKII, but it's not hooked to anything.
If you need more details or pics, just ask.
This is the first game i've ever been inside of and it's a learning experience.
If it helps, MKII ran fine.
Thanks,
Joe
