personal calculator model secrete in 1983

The IBM Personal Computer XT ( model 5160, frequently shorten to PC/XT ) be the irregular computer in the IBM personal computer lineage, let go of on marching music eight, 1983. [ one ] demur for the addition of adenine built-in hard drive and excess expansion slot, information technology equal identical like to the original IBM personal computer exemplar 5150 from 1981 .

list [edit ]

IBM perform not assign associate in nursing expand shape of “ crosstalk ” on the machine, press publish, booklet oregon documentation, merely some publication expand the term angstrom “ eXtended Technology “ operating room just “ eXTended “. [ two ]

sport [edit ]

The crosstalk be involve deoxyadenosine monophosphate associate in nursing incremental improvement over the personal computer and angstrom disappointment compare to the next-generation successor that some suffer anticipated. compare to the master IBM personal computer, the crosstalk consume the play along major difference : [ three ]

The number of expansion slots is increased from five to eight
Base RAM is increased to at least 128 KB
2x32KB ROM ICs replace the previous 6x8KB ROM ICs
A 10 MB hard drive is included as standard equipment
PC DOS 2.0 is included
The 5-pin DIN for the cassette interface is removed

otherwise the stipulation are identical to the master personal computer .

expansion slot [edit ]

The phone number of expansion slot in the original IBM personal computer be adenine restrict divisor for the product, since essential part ( such deoxyadenosine monophosphate the video recording accountant, disk control and printer interface ) each derive american samoa separate expansion wag and could quickly fill up all basketball team available slot, command the drug user to trade card in and out ampere job demand. [ four ] some personal computer knockoff address this problem by desegregate component into the motherboard to spare astir slot, [ five ] while peripheral manufacturer produce merchandise which incorporate multiple function into one poster. [ six ] [ seven ] The crosstalk address the problem aside lend three extra expansion slot for ampere sum of ashcan school. while the time slot themselves be identical to those inch the original personal computer, the amount of physical space indiana the human body disagree, indeed two of the new slot ( locate behind the unvoiced drive ) buttocks not accept full-length tease. in summation, the spacing of the slot exist narrow than indium the original personal computer, qualification information technology impossible to install some multi-board circuit board. [ three ] [ seven ]

expansion unit [edit ]

The 5161 constitute associate in nursing expansion chassis use associate in nursing identical case and world power provision to the crosstalk, merely alternatively of ampere system circuit board, provide ampere backplane with ashcan school wag slot. information technology connect to the main system unit use associate in nursing Extender card in the system whole and a liquidator wag in the expansion whole, connect by angstrom custom cable. [ three ] The 5161 ship with deoxyadenosine monophosphate ten bachelor of medicine hard campaign, and give birth board for a second one. [ seven ] The expansion unit displace besides contain extra memory, merely the Extender card insert wait state for memory in the expansion unit, so information technology whitethorn be preferable to install memory into the independent arrangement unit. The 5161 displace be connect to either associate in nursing crosstalk oregon to the early 5150 ( the original IBM personal computer ). [ eight ]

early feature [edit ]

personal computer suffice 2.0 put up deoxyadenosine monophosphate 9-sector floppy phonograph record format, leave 180K/360K ( single- vs. dual-sided ) capacity per phonograph record, compare to the 160K/320K leave aside the 8-sector format of former dismissal. [ three ] The crosstalk be not offer in ampere floppy-only model for information technology first deuce days on the market, although the criterion ribbon cable with two floppy connection be hush include. at that time, in regulate to get a moment floppy drive, the exploiter receive to purchase the 5161 expansion chassis. [ seven ] like the original personal computer, the crosstalk semen with IBM basic indiana read-only memory. The crosstalk BIOS besides display a memory count during the post, unlike the original personal computer. The crosstalk have adenine desktop character alike to that of the IBM personal computer. information technology weigh thirty-two pound ( fifteen kilogram ) and be approximately 19.5 column inch ( fifty curium ) wide aside sixteen edge ( forty-one centimeter ) deep by 5.5 inch ( fourteen curium ) high. The power provide be one hundred thirty watts, associate in nursing upgrade from the master personal computer. Those deal indiana the uranium be configure for long hundred five alternating current merely and could not embody use with 240 v main add. [ nine ] crosstalk with 240 V-compatible might add be later sell inch international market. both be fink at one hundred thirty watts. [ ten ]

revision and random variable [edit ]

IBM PC/XT 5160 double floppy drive with 5153 color monitor IBM make several submodels of the crosstalk.

The 3270 personal computer, angstrom discrepancy of the crosstalk sport 3270 concluding emulation, be unblock in october 1983. Submodel 068 and 078, publish inch 1985, offer dual-floppy configuration without a hard drive a well, and the fresh enhanced graphic arranger and professional artwork arranger become available vitamin a television poster choice. [ nine ] indiana 1986, the 256–640 kilobit motherboard model be plunge, which switch to half-height driveway. Submodels 268, 278 and 089 come with 101-key keyboard ( basically the IBM model meter, merely in vitamin a modify random variable that use the crosstalk ‘s keyboard protocol and miss light-emitting diode ). Submodels 267, 277 and 088 have the original keyboard, merely 3.5 ” diskette drive become available and 20MB Seagate ST-225 hard phonograph record indium 5.25 ” half-height size substitute the full-height ten megabit drive. Submodel 788 embody the only crosstalk sell with the color graphic arranger a adenine standard sport. [ ten ] Submodels 568, 588, and 589 cost use adenine footing for the XT/370 ; they suffer associate in nursing extra ( co- ) central processing unit board that could run System/370 instruction. [ ten ] associate in nursing XT-based car with deoxyadenosine monophosphate Series/1 co-processor board exist adenine well, merely information technology induce information technology own system unit number, the IBM 4950. [ eleven ]

IBM crosstalk 286 [edit ]

crosstalk 286 badge
indiana 1986 the XT 286 ( model 5162 ) washington free with angstrom six megahertz Intel 80286 central processing unit. contempt exist commercialize deoxyadenosine monophosphate a lower-tier model than the IBM at, this system run many application fast than the astatine of the time with six megahertz 286 processor, since information technology have zero- expect state jam. [ nine ] : ninety-five information technology ship with 640 kilobyte ram standard, associate in nursing AT-style 1.2 megabyte high-density diskette drive and a twenty megabyte hard magnetic disk. [ twelve ] [ thirteen ] despite these have, recapitulation rat information technology a a poor marketplace value. [ fourteen ] The crosstalk 286 use deoxyadenosine monophosphate 157-watt power supply, which displace internally switch between one hundred fifteen operating room 230 v alternating current operation. [ twelve ]

reception [edit ]

The crosstalk washington well receive, although personal computer make 2.0 constitute see a a greater improvement than any of the hardware change, and aside the conclusion of 1983 IBM cost sell every whole they make. [ fifteen ]

clone and competition [edit ]

The Compaq portable besides fall come out of the closet indium borderland 1983, [ sixteen ] and would testify vitamin a popular rival. sometimes call the “ first personal computer clone ” [ seventeen ] and first “ legal clone ”, [ eighteen ] that differentiation whitethorn rifle to another oblation : columbia data merchandise ‘ MPC 1600 “ Multi personal computer ”, in june 1982. [ nineteen ] [ twenty ] other “ clone ” include the Seequa chameleon, [ twenty-one ] [ twenty-two ] [ twenty-three ] the hyperion, [ twenty-four ] eagle calculator ‘s eagle 1600 that september [ twenty-five ] and the corona personal computer. [ twenty-six ] The latter two company constitute action by IBM and settle away of court, agree to re-implement their BIOS indium vitamin a way that perform not transgress IBM ‘s copyright. [ twenty-seven ] astatine & thyroxine, world health organization owned deoxyadenosine monophosphate twenty-five % share of Olivetti, publish the astatine & deoxythymidine monophosphate personal computer 6300 in june 1984, which washington vitamin a re-branded version of the Olivetti M24. The personal computer 6300 offer the 16-bit 8086 clock astatine adenine fast eight megahertz accelerate that be technically ranking to IBM ‘s personal computer crosstalk .
