Two weeks ago Spawn2 came down stairs carrying on old computer: IBM PC 365, dual Pentium Pros at 200 MHz and 1 MB on chip cache. It was a screamin' machine for its time running NT3.51, but its time is long gone. He said that he tried to boot it up, but it was dead. I asked him if he wanted me to fix it and he did. He likes retro electronics for some reason.
The old power supply was fried, but I found a replacement on-line for $20 with free shipping. It arrived today and I put it in after giving the innards of the box a good cleaning. Booted right up!
The last OS on it was some version of Suse Linux. It took me about a dozen guesses before hit on the correct root password.
I have no idea what I'm going to do with this antique, but it does run. I think that once I had BeOS running on it for fun. I just might try that again just for $hits and giggles.
Or because it is an IBM machine perhaps I should seek out a really old version of OS/2.
