i'm using one of the cheaper jammaboards.com harnesses in my jamma cab, and while it works, i've got a .8v drop on the +5 line between the switcher and the edge connector, so i've got it set at 5.8 to get an even +5 on the board.
the way the harness is it uses 1 18gauge wire connected to all 4 pins for +5v. from what i've read online, this is why i'm having the problem. can anyone confirm that?
what is the best thing to do, (aside from buying another harness?) if i were to simply remove the one +5 line and replace it with 4 wires, one to each pin on the edge connector, would that work and cut down the voltage drop?
the main thing i'm concerned with - is running the board like this gonna cause any issues down the road with my jamma pcbs, as far as screwing them up, provided the board voltage stays at 5 volts?
edit - if it means anything, i'm running a very clean (edge connector wise) data east real ghostbusters pcb in it right now.
