Keeping you stuff backed up so you can move it to another machine is good advice to everybody. I moved everything I wanted off that drive a long time ago. It seems like a lot of people think XP was the apex of Windows operating systems. I liked it better than 7 or 10.
You piqued my curiosity on that one. I sold a Commodore 64 with disk drive, monitor, dot matrix printer, and a plotter printer for $50.00 to a guy back about 1998. It couldn't do much, especially by today's standards, but if you knew how to work the plotter printer you could produce pretty cool drawings/diagrams. I ran into someone who does custom engraving work and uses a C64 to operate the engraver. She puts one job on each cartridge. When it's time to go to work she just plugs it in and goes.
