Actually, the 486 is quite powerful....
People are so wealthy now with all the storage and processing they have available. You may not believe this but the Hubble was originally launched in 1990 with an USAF DF-224 computer that had a whopping 32k of plated wire memory.
Total.
32k
Yes, the HST was essentially using the equivalent of a Commodore VIC-20.
In the first servicing mission the computer was upgraded to run with a co-processor, a beast 386 with a meg of RAM. Talk about a jump. Going from 32k to a full Meg. it's like moving from a cardboard box to a mansion. This 486 with 6 times more memory that was installed in 1999 is sheer luxury.
