yeah... well none of this sounds impossible.. it's just not practical..
first off, what the hell is a BeOS computer? :D I've never heard of it, and
I'm a CS major.. but I'm just curious about that..
but would you be able to run two of these vinyl-data things on one of those
computers? if not, someone would have to have two BeOS computers (which
sound like either mini's or mainframes? if they were pc's I think I would've
heard of them) and then 2 of these gizmos..
although this is quite interesting.
