IBM Portable Personal Computer :: Retrocomputing on the green

The IBM Portable Personal Computer 5155 model 68 was an early portable computer developed by IBM after the success of Compaq's suitcase-size portable machine (the Compaq Portable). It was released in February, 1984, and was eventually replaced by the IBM Convertible.


Retrocomputing (a portmanteau of retro and computing) is the use of early computer hardware and software today. 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.[1] Retrocomputing often gets its start when a computer user realizes that expensive fantasy systems like IBM Mainframes, DEC Superminis, SGI workstations and Cray Supercomputers have become affordable on the used computer market, usually in a relatively short time after the computers' era of use.


Con il termine retrocomputing si indica una attività di "archeologia informatica" che consiste nel reperire, specialmente a costi minimi, computer di vecchie generazioni, che hanno rappresentato fasi importanti dell'evoluzione tecnologica, ripararli se sono danneggiati, metterli nuovamente in funzione e preservarli.
