There are folks that collect vintage computers but really things like Xboxes and Playstations were so plentiful, odds are low anyone would want them for a collection (Not trying to be mean).
Once I've removed personal information (Which if they're old enough, that might not even be an issue) I donate such things to Goodwill. They'll either resell 'em or sell 'em to scrappers to remove the precious metals from 'em; either way you get a tax writeoff and get 'em out of your hair...
Thanks. Goodwill is an option. Will redo the hard drives even thought I know it won't really "erase" the information, just make it harder to "read".
