For the last few weeks scientists and engineers at NASA have been trying to fix a problem with the Hubble Space Telescope which threatens to end the observatory's operation if it can't be solved. Memory read-write problems are being seen in the payload computer, a Nasa Standard Spacecraft Computer (NSSC-1) built by IBM in the 1980's.
The design is based on a computer first launched on a spacecraft in 1972, and it was replaced in 2009 as part of the final servicing mission, albeit with a near identical piece of hardware still using dozens of discrete integrated circuits to implement the core logic.

This is one of two primary computers on the spacecraft, the other is a space hardened 486 system that replaced the original main computer in 1999.
