Retrocomputing

Retrocomputing is the use of older computer hardware and software in modern times. Retrocomputing is usually classed as a hobby and recreation rather than a practical application of technology; enthusiasts often collect rare and valuable hardware and software for sentimental reasons. However, some do make use of it. Retrocomputing often starts when a computer user realizes that formerly expensive fantasy systems like IBM mainframes, Digital Equipment Corporation (DEC) superminis, or Silicon Graphics (SGI) workstations have become affordable on the used computer market, usually in a relatively short time after the computers' era of use.
