What's amazing is how RELIABLE those things were.
We have a couple of SparcStation 5 units STILL RUNNING because a professor refuses to let them go. They have 2GB hard drives (yes TWO gigs) and 128MB of RAM. These things were outrageously expensive when they came out; I'm guessing Sun spent a lot of the extra money on overengineering the hell out of everything.
"Sir this version of Solaris is no longer supported. We can't keep running it unless we block access to it from the Internet."
"It doesn't need Internet access, just block it and let me keep using it."
"Sir this machine is older than some of your students. If it dies we cannot replace any parts."
"No problem just leave it up."
"Just leave it."
Ahh, academia. :)
