One of the original Apple-1′s, the first ever Apple computer that Steve Jobs sold from his parents' garage in 1976 is up for sale at Christie's in London in for a whopping £150,000.
Interesting to note is that the Apple-1 came with 8K of RAM. The current Mac Pro can take in 64 GB RAM.
"Apple's first shot at a computer comes with all the fixings: manuals, box etc. and even a nice letter from Jobs himself. Only 200 of these machines were produced with only a few surviving today. This model of Apple-1 is actually the higher-end model that included the read-write capability for an extra $75 at the time. The actual unit cost $666.66 back then and did they start selling them on Friday the 13th?"
