Hello~! I've got a pretty sweet X68000 setup now; Expert HD unit (Clean), XRGB, joysticks and soon to finish ps/2 keyboard adapter. My question is since the Sharp has a 100v original PSU unit, do I need a step-down converter? Will I fry its already famously delicate electrolytic condensers?
Yep. You need a stepdown converter. I got mine from voltageconverters.com through Amazon. Works great and built like a tank. I got the 500 watt model.
