I may be wrong but last upgrade to the Hubble's computer system was an Intel 486DX chip. The
first with built-in math co-processor. The Hubble runs no background crap, Windows, e-mail, screen
saver, pretty pictures. It just crunches numbers. Wonder if next upgrade will be to an Intel Pentium 1 ?
I'm still running a Pentium-Pro myself. I don't use computers for photography or music, just for
number crunching.

Best regards,
