A computer retained for operations for reasons other than current technology. ThinkingOutLoud.DonaldNoyes.20110919
Some people, including myself, like to keep computers they have used far beyond their most useful and efficient lifetimes. They retain OperatingSystems, Programs and Data which have been made a legacy.
These are Computers which are still fully operational and function as they did 5, 10, 20, and even over 30 years ago.
I guess among other names, you might call those who have them Computer Collectors, or Historic Computer Preservationists.
There is a MarginalValue? in the present time for keeping such computers in addition to their Historic Interest.
