Mame_freak,
I'm planning on mame-ing it with an ArcadeVGA card. I realized, thankfully before hooking it up, that I needed an isolation transformer.
Any iso xformer will work as long as it is 1 to 1. The Happ model will work as well as any other.
Sorry to hear about your monitor, let me know if you are looking to sell it. I'll give you $15 for it.
Thanks,
Todd
