Old kit, old data
I have data on my computer that is almost forty years old. It's still valuable. I've had to go through a ridiculous number of format conversions to keep it that way. Some of it started out saved on TRS-DOS cassette tapes. Some started out on Commodore Scripsit cassette tapes. It's gone through TRS-DOS floppy disk to CP/M to MS-DOS, and I had to keep at it as the programs I used to record it went quietly into the sunset. Right now it's on a NTFS hard drive, and if I take it any further, it'll all be saved as RTF.
The thing is, I still use that data (I am, and live with, a novelist. They're word-processing files.) Some of the conversions it went through were only possible with a specific machine (Commodore 128) which was only available for a few years. If I'd missed out on that machine, the files would be gone.
So give some consideration to a bloke who wants his old kit back. Who knows how long it'll be for the files to become the digital equivalent of cuneiform? That can happen rapidly and surprisingly.
