A Convex SPP1-2 supercomputer on eBay for $99. In Northern Virginia .... imagine that. Not like anyone in Northern Virginia is the world's largest single market for snoopercomputers, or anything like that -- oops, what a giveaway.
(No, it wouldn't look good in the living room. Anyway, the SPP-UX OS it runs isn't available any more. Besides, this thing requires 16 amps at 240 volts. That's almost the power consumption of the average electric oven and cooktop.)
