"The shuttle operators also need eight-inch floppy disk drives, which were outmoded before the end of the 1970s."
"Reassuringly, the scientists say that the parts are not required for the shuttles themselves, but for servicing and support equipment."
"It's like a scavenger hunt," Jeff Carr, a spokesman for the United Space Alliance, the company contracted to run the shuttle fleet, told the New York Times."
"On ebay.com (apparently one of Nasa's chief stamping grounds), it was possible yesterday to find a couple of 8086 central processing units, and even an 8086 users' manual."
"Bidding for one of the units was up to $7 (£5) with the manual going for $3. Funding for the American space programme is not as lavish as it once was, but it is thought these amounts would be within the budget."
