Jamma Extension

13-06-2013 7:10pm#1I can get em on ebay for about €15 posted but maybe someone here has a spare they are looking to offload for less ?
Basically I have a Supergun and Neo Geo MV-A1 and when the PSU is plugged in it's a very tight squeeze to get the MVS carts in/out. A jamma extension would tidy things up nicely.0

Is it this you're looking at?

I have one I don't need. I had two, sold one to Technofreek (at least I think it was Technofreek?) but there were issues with it as it turns out that harness has no -5v wire.
If you want to take a chance on it you can have my one for €5. I can throw it in the package along with the vogatek supergun.
Yeah that's it.
No -5v wire? Could you count the wires and see ?
I know very little about this stuff and don't want to break anything

Those extension harnesses don't have a -5v wire as standard. If you look at the picture in the auction, zoom in and count over three markings on the black connector from the right.
There's a little '-5' written on in gold with an arrow pointing to a pin. You'll notice that the pin in silver and has no wire attached to it.
Why they didn't wire it up I don't know.
It wouldn't break anything, but some arcade PCBs require -5v to work (Raiden being an example, there's no sound when you don't have -5v). Technofreek had issues with it in his cab, I can't remember what they were though.
Best extension harnesses to go with are ones made by FrancoB. They're pretty expensive though and he's not making anything at the moment due to his own personal projects

In that case... Wrap her up, she's coming home 0 -

:pac:
Yeah always knew that lad was a cowboy selling dodgy gear!
