I've heard rumors of people using a DB25 printer switcher as a JAMMA switcher, yet have found very little info on the subject (aside from Niobium's great yet very complicated write-up over at arcadezone.org). So here's my question: Would it be possible just to hack up one JAMMA harness (for input), multiple JAMMA extensions (for outputs), wire them to DB25s and use a straight printer switcher like this one? http://www.buy.com/prod/belkin-4-po...lkin-slimswitch-5-x-db25-female/10007729.html
That's the switcher I have. My thought is, to wire up everything except the +5, -5 and 12v lines to the input/outputs, then install separate switches for the power lines. While the power switches are off, move the main rotary switch to the board you want, then reapply power (to avoid the issue of having more than one board powered up while in mid-position while switching the rotary). The rotary switch completely isolates the lines from each position, so having the switch set on 3 and powered up powers only that board and not all of the others at once.
Does any of this seem feasible or worth the time/effort?
