Hi recently acquired an mk3 revision 3.1 board. At first the image was unstable and kept resetting so I had the turn up the 5v supply a notch. Sorted.
Next issue is that when I power on the board I get the cmos invalid, factory settings restored, dipswitch coinage used error. Needless to say my settings and stats don't save on power off.
A quick peek around the board and I found that there was no battery at all. I took the battery from a faulty mk1 board, metered it at 3v and stuck it in my mk2 board.
I still get the same error after putting in the battery. Oddly though if I go into the test menu, make my adjustments and exit back to the game I get a CMOS OK, dipswitch coinage message.
Switch off the machine and I'm back to the cmos invalid message.
Any ideas? Thanks
