Beginning with a simple renovation

[NES4Life]

I'll keep you in mind if I do take the JAMMA route.
Think I'll Hangly it up for the time being.

Really enjoying tinkering with the cab - the best part is that if I ruin anything it only cost me £15!
Any tips?

So here are my beginners questions (please don't laugh too much at me):
- on PCB pin-out diagrams, do Spkr+ and Spkr- carry the actual audio signals for a speaker or do they relate to   volume control of a speaker (e.g hooking up two microswitches would allow me to step the volume up and down). If I have a large speaker with just 2 pins for connection what PCB pin-outs would I hook up to it - I'm guessing it needs power and audio - or are they passive and just need an audio signal and GND? I'm pretty lost with this speaker and can't see why there's no noise

- Where can I get a new 44-pin Pacman harness that doesn't cost the earth? I'm not sure the wiring is incorrect and the last owner soldered everything haphazardly. Otherwise where can I get a wiring kit similar to a JAMMA harness kit?

Spkr + and spkr - go to the two terminals on your speaker

Thanks Etienne - simple

The previous owner has pemanently soldered the 'Table' pin to GND - directly on the PCB!
So when I choose 2 player the second player gets it upside-down. Gonna need some de-soldering mastery to split that up again. Did they think the edge connector was just there for a laugh?!

Another question:
- should all the p1 micro switches have P1-GND sent to them?

[Etienne MacGyver]

If the bridge is done with a wire, you can simply cut it, of desolder it.

Many times this is a dipswitch or jumper, but i dont know your board.

normally the switches make contact with ground to activate, and because of that you can simply daisychain the ground from switch to switch, so you end up with one ground wire that jumps from one switch to the other like on my Crazy Kong harness:



Dont know if you see it good enough on this pic, but the green/yellow wire is the ground in my case.

Thanks again - daisy chaining ground did seem like the obvious choice - on the PCB there are a number of pins labelled GND and 1is labelled P1 GND.

The bridge is just solder so can simply be desolderd.

So, due to the nature of my inexperience - I'm selling the Hangly-Man PCB to someone who can care for it and get more out of it than me! I'll take JAMMA for beginners please.

Please see the Buy/Sell/Trade section of the forum - or just PM me.

Thanks for all your help - I'll be asking more questions when I get my JAMMA replacement!

Sold to Muerto!
It's great to keep these things with real enthusiasts.
So my story begins with JAMMA.
