Lol, seriously though, after finishing up the Neo Geo, my next project is a Mortal Kombat 2 restoration. I got it in the same lot as the Neo Geo, and it was converted to a Rampage World Tour. It was working when I picked it up, but obviously it has a few issues in the monitor. Well, I sold off the Rampage board, and got a MK2 board to go in it. Then I found out that it has a separate sound board so I picked up one of those too. I still need to get the cable that connects them. Well Last night, I tried to start up the MK2 board in it, and nothing happened. I tried another Jamma board I had(Class of 1981 Ms Pac Galaga), and it produced a high pitch whine and some screen garbage. I tested both the boards in my Simpsons cab and the Class of 81 board worked fine and the MK2 board ran through some test menus and then came up with a screen that said CMOS Coinage. Any ideas what that means? I am assuming that I need to adjust or replace the switching power supply in the MK2 cabinet. Pics of her as she was when I picked her up are attached!
