Capsule containing The Moody Blues tape and a six-pack of beer had been lost since 2000

A time capsule assembled by Steve Jobs and containing his personal computer mouse has been unearthed in Colorado 30 years after it was buried.

The capsule was initially put in the ground to accompany Jobs' delivery of a speech about the future of technology at the Aspen International Design Conference in 1983.

To commemorate the occasion, the Apple co-founder - who died in 2011 - placed his personal computer mouse from the early Lisa computers in the capsule, with attendees also donating a range of items.

The simple one-button mouse from was the first commercially available and was found sealed in a protective plastic bag. The Lisa computer was released in 1984 and eventually evolved into the first Macintosh.

Initially, the intention was to dig up the so-called 'Steve Jobs' capsule in the year 2000 but because of a landscaping project in Aspen that year the location of the sealed metal pipe was lost.

In September last year - some 13 years after it had been lost - a National Geographic programme called 'Diggers' managed to locate the historic container.

They have released a video ahead of their first show (which debuts on 25 February) detailing what they found in the capsule. Other items include an eight-track recording of The Moody Blues, a a six-pack of beer and a Rubik's Cube.
