I’ve started to take a look at an original Tehkan World Cup PCB in order to start to get the electronics side of things done before I move onto the conversion of my empty Atari Dunk Shot cabinet to a Tehkan World Cup cabinet.

The PCB itself was filty when I dug it out of the loft so I decided to give it a good clean. Whilst I was waiting for it to dry I started having a look on the Internet for pinouts so I could wire up a Jamma adaptor.

I came across two possible pinouts. One on Andysarcade.net and the other on Powerstrike.net.

Andy stated on his website that the powerstrike pinout was incorrect. I found this was partly true, as the pinout was correct but the wrong way round e.g. A and 1 was really V and 18 according to Andy’s list. In fact I believe they both use the wrong labelling for the connections because the PCB is labelled B1-B18 on both connectors on the parts side, and I suspect that the solder side is classed as A1-A18, so that’s what I’ve used with my attempt of the pinout. The connectors are also labelled J1 and J2 on an original PCB so I’ve also made that clear on my diagram. Hopefully it makes more sense?

I’ve yet to confirm my wiring is 100% but I’m fairly convinced it is. I will give an update on this when I’ve done my Jamma harness. I have used the Tehkan World Cup manual I have on my site which can be found here. The only problem with the manual is that it is not the most readable as it looks like it has been photocopied over and over, but it seems to be the only one on the Internet!
