Yesterday, a "superb example" of one of the first personal computers — an Apple, not a PC — was auctioned off for a whopping $210,700 at Christie's auction house in London. Apple co-founders Steve Jobs and Steve Wozniak first sold their "Apple-1" computers from Jobs' parents garage. The "superb" Apple-1 specimen auctioned off includes all the original packaging and instruction manuals, the original dated invoice, and a signed note from Jobs. Auctioneers hope it will fetch a price well into the six figures. Here's a look, by the numbers:

The price equivalent today, after adjustments for inflation. ("Even 34 years ago Apple’s hardware was shockingly expensive," quips Steven Mostyn at The Tech Herald.)
