Man constructs replica of Apollo guidance computer
The New York Times has a fun story about John Poltorak, who spent his free time the last few years building a reconstruction of the guidance computer used in the Apollo space missions:
The AGC is a piece of computing history. It had a 1MHz processor, 1K of random-access memory and 12K of read-only memory. By contrast, typical desktop computers today have about 1,000 times the processor speed and about 500,000 times the RAM, and have dropped ROM for hard drives with millions of times the capacity.
Next up for John: a really cool abacus, or maybe a Pong console? (Thanks to Jim for sending in the link.)
