Nasa doesnt like new hardware. Maybe becouse the average Nasa dude age
is around 40-60
.
Or maybe because they design the things to WORK. Most people dealing
with PCs have absolutely no concept of reliability and things that
MUST work the first time and EVERY time. That's why they used tried
and tested (and usually redundant) hardware on high-reliability
operating system (VxWorks in this case).
Mac? Please! MacOS / OS X wouldn't know true reliability if it was
hit over the head with it!
Of course, the system in question has absolutely NO connection with a
Mac at all. It's quite odd to see people who automatically assume
PowerPC == Mac. Do these people think that Nintendo Gamecubes are
Macs as well? Cisco routers? Hell, the Newisys 2100 Opteron server
has a PowerPC processor in it!
I'v seen some Amiga advocacy www about Nasa
"obsolete hardware syndrom".
It could have something to do with the fact that the computer system
used costs about $2000 in a multi-multi-million dollar (billion
dollar?) machine, but if one tiny bit of that computer hardware or
software failed the whole machine is a waste.
When you start dealing with numbers like that, reliability is the ONLY
factor that matters. PC hardware and software and just NOT designed
with this kind of reliability in mind.
