power it up by all means, but the chances of running AOS-whatever version are highly unlikely. AmigaOS requires the custom chipset to run (Exceptions being a modified version for the Drako line of computers, and AmigaOS 4 for AmigaOne) or software emulation thereof.
But who knows, you might well have a missing link system there, and even if it blows, who cares? it won't effect your amigas.
A word of warning though, don't connect anything to it that you can't readily replace or afford to loose.
Oh and good luck :-D
