I'm having problems with a gottlieb cleopatra. About half of the insert lights are locked on. Someone has previously replaced the MPU with a Ni wumpf pcb0001 Rev C. (Around 1999 or 2000) I've already repinned the interconnect, checked a13 lamp transistors as well as all of the 74175s. When put in the lamp test, the locked on lamps pulse slightly. For whatever reason, I can't get onto Ni wumpf's website, not sure if it's down for maintainence or they're closed. If someone has either the manual or schematics for this board, it would be much appreciated.

Unfortunately after finally getting around to looking at the board, U5 is only outputting some of the strobe lines. Originally, I believed this to GAL U5 failing, however more and more software bugs have become apparent in the last day or so.

For example, none of the drop target switches read in game, however when put into switch test, they read fine. Certain solenoids stopped working in game, but work in the test mode. I also noticed the LED flashing a single time. More than likely, I'll need to obtain a new ROM. Does anyone know where I can get either the code or the whole rom?
I'll be checking with PBR as a first step, but I'm not sure who else might stock it.
