One of the 10 boards I got in my Argentina haul. Kung Fu Master.
ROMs are Spartan X
Board seems in good condition, little bit of corrosion, needed a clean. No jumpers or prior work on the board that I can see.
No obviously missing parts! I did notice that one of the DIP switches has one DIP part missing, I can move it with a sharp tweezer, so have it all set for free play.
Above the 3 stack, with top board missing.. There is some browning/ageing of the resistors in the sound section, but nothing missing and the bases of them seem clean
Before powering it up, I did a quick check on 5V and 12V to make sure they weren't shorted from the get go.
All seemed fine. Grabbed an adapter for IREM from Henrik, and put some power through it.
The power supply is putting out 5.3V, to give me 5v on a few of the ICs. Happy with that.
Music and sound seem good. No backgrounds. Can coin up.
I decided to check all the EPROMs, pulled them all, gave them a good clean with a fibre glass pen.
Few pins checked bad in my EPROM burner, as hard as I tried, I couldn't get those pins to check out. Non of the pins are particularly fragile. No corrosion, but there is the usual mark where they have been sat in the socket for a long time.
I burned new EPROMs for these. All the ERPOMs are 64s apart from a couple of 128s.
I reseated and cleaned the pins on all the socketed chips, on all three boards. Nothing major to report, all nice and shiny now. These look to be originally socketed, ie not fixes done, either that or they are VERY tidy work!
TOP Board
MIDDLE Board
LOWER Board
After putting the chips back in and turning on..
Little bit of progress. After watching a few videos and reading repair logs, I turned my attention to the custom chips. I was hoping beyond hope that they weren't dead.
I decided to give them a lift/shift around, screw driver under the end and a slight lift up, just to get the connection moved and see if it was those "connection marks" causing bad connection.
and....
BAM! Seemed to do the trick. The chip was only moved, maybe 0.5mm and it's tightly in the socket.
Easy fix, but sharing incase the "slightly lifting the custom chip to recover the background" is useful to someone else in the future.
Its now installed in my Jamma cab for a few games. Its hard as f&^k.. Good to have it working, even if it isnt my fav game!

A simple game but very addictive, I like it a lot.
