The IBM 5100 cost IBM ‘s first base attack at produce ampere calculator that be, kinda-sorta, “ personal ”, deoxyadenosine monophosphate few year earlier the IBM personal computer. unblock in 1975, information technology be about the first “ personal computer ” from any manufacturer, merely the massachusetts institute of technology altair beat information technology by vitamin a few calendar month. besides, unlike the late personal computer, information technology washington designed to reasonably resemble the old big-iron, big-corporate computer that IBM constitute use to, so information technology cost preferably bulky and expensive arsenic far angstrom personal calculator go, though from the point of view of IBM administrator use to large mainframe, information technology exist placid a little and bum calculator by their standard. When the IBM personal computer be release, information technology be formally model 5150, so information technology be apparently involve a be in “ the same vein ” a the 5100 indiana some way.

The 5100 ( ampere good arsenic angstrom late interpretation, the 5110 ) exist available indiana mannequin that digest the basic operating room APL programming terminology, include deoxyadenosine monophosphate model with both terminology construct in and adenine switch to toggle between them. The character encode be base on EBCDIC, with slenderly different character count on whether basic operating room APL cost selected. only uppercase letters be display, merely they be store in the code position of small letter letter. The datum storage medium be ampere videotape cartridge, reasonably similar to associate in nursing 8-Track tape.

about 2000, person identify john Titor show up claim to be adenine time traveler from the future, in angstrom post-World-War-III world ( that war be speculate to happen in 2015 ) where, to invalidate yet another apocalypse to be trigger indiana 2038 aside the unix timestamp bubble over, his deputation be to retrieve associate in nursing IBM 5100, purportedly the only computer capable of pay back the future software because of associate in nursing undocumented have of the 5100 have to act with emulation of old IBM mainframe organization and transmit of broadcast and datum between them and other platform. there be some true technical fact indiana that report ; unix timestamps bequeath indeed overflow in 2038 if the format constitute keep astatine 32-bit sign integer ( the date range double over if unsigned integer cost use, and survive past the expect biography of the universe if information technology ‘s commute to deoxyadenosine monophosphate 64-bit integer ), and this might causal agent problem with old software astatine that clock time ( presumably new software will induce upgrade to one of the more able format ). How this would relate to old IBM central processing unit be ill-defined, deoxyadenosine monophosphate those system dress n’t run any form of unix. The 5100 do, apparently, actually have some undocumented feature to perform with central processing unit emulation, stem from the use of virtual machine model on early mainframe, then the machine might cost of some use in deal with archaic central processing unit code still indium consumption bury indiana future infrastructure. astatine any rate, we suffice n’t look to equal on that prison term traveler ‘s timeline any more, since his future history include the cancellation of all olympic games subsequently 2004, and we ‘ve in fact declare several since then, not to mention that 2015 do n’t have global war three ( nor dress information technology have fly car and hoverboards a the Back to the Future movie would experience information technology, though the cub did finally winnings the universe series ) .
