I have some chit, that's older than that. I also have a dell L500R
that I acquired from my step dad's mom. She's in a nursing home
suffering from dementia, so she doesn't know if it's Monday, or July
4,1776.
Anyway, normally I would've just scrapped a machine that old for
parts, but I didn't feel like it would be the right thing to do, since
she's still alive. So, on a whim, I stuck a 500gig hard drive in it,
which the bios saw, and I loaded White box 4 on it, and I use it as a
archiving/file storage machine.
The machine runs just fine. It's got 512mb of ram in it, and super
fast 433 mghrtz intel celeron cpu. It'll run circles around a comodore
vic 20, or a TRS 80.
