Thanks for spreading the info. At last test, battery was flat. I imagine it is likely the thing has no shot without the missing components. And given the guy I got it from got it out of a recycling place, who knows what may not have been thought of as a component that got left behind. For me, I'd also love to learn more on the history of this thing even if no useful code is recovered. I will likely get this sucker into a display and make it a quirky centerpiece of the sega channel collection of stuff (and there is more than I'd imagined).
