If i take an old game like "dig dug" and make it into a 48-in-1 jamma machine can i ditch the iso transformer and just have a pcb, powersupply and monitor???
you ditch the old huge iso and install a small new one(most of the older iso's ave more than one input output and can really screw up things if wired wrong)
but if you are using a new monitor sometimes you can get away without an iso but be shure the monitor does not require one
You will need an iso if you are going to use an older arcade monitor. It doesn't have to be the big huge mofo that is in there now, but you will need one.
