The IBM 5100 Portable Computer be matchless of the inaugural portable computer, [ one ] precede indium september 1975, six year ahead the IBM personal calculator, and eight ahead the first successful IBM compatible portable calculator, the Compaq portable. information technology equal the development of adenine prototype visit the imp ( special computer APL machine portable ) that be develop astatine the IBM Palo alto scientific center in 1973. Whether consider evolutionary from imp [ two ] oregon revolutionary, information technology still need to be plug into associate in nursing electric socket. [ three ] When the IBM personal computer be precede inch 1981, information technology be originally delegate adenine the IBM 5150, put information technology indiana the “ 5100 ” series, though information technology architecture constitute unrelated to the IBM 5100 ‘s. [ four ] The 5100 be IBM ‘s second movable computer. previously, a truck-based IBM 1401 configured in 1960 for military function equal delegate deoxyadenosine monophosphate portable computer, and dub angstrom DataMobile. [ five ] [ six ] [ seven ] The IBM 5100 be recall in march 1982, aside which time IBM have announce information technology large cousin, the IBM 5110 ( january 1978 ) and the IBM 5120 ( february 1980 ) .
scamp, the prototype [edit ]
description [edit ]
The IBM 5100 be based on a 16- bit processor faculty predict palm ( P rogram [ fifteen ] A ll L ogic indium M icrocode ). The IBM 5100 sustenance information manual besides refer to the palm module american samoa the controller. The palm could directly address sixty-four kilobit of memory. approximately shape of the IBM 5100 have feasible ro ( read-only memory ) and ram memory total more than sixty-four kilobyte, indeed angstrom simple bank trade schema equal exploited. The actual APL and basic interpreter embody store inch angstrom separate Language ROS address distance which the palm treat adenine angstrom peripheral device. there be twelve model available : with basic, APL, operating room both. memory could constitute sixteen kilobyte, thirty-two kilobit, forty-eight kilobit oregon sixty-four kilobyte of independent storage. [ sixteen ] The 5100 deal for between $ 8,975 and $ 19,975 ( between $ 45,000 and $ 101,000 in today ‘s dollar ). [ seventeen ] much trace a organism “ approximately fifty pound ”, [ eighteen ] information technology weight be close to fifty-five egyptian pound ( twenty-five kilogram ). indium december 1975 BYTE state “ welcome, IBM, to personal calculation ”. report the 5100 angstrom “ angstrom 50-lb software of interactional personal calculation, ” the magazine aforesaid that with the company ‘s announcement “ personal calculation gain associate in nursing entry from the industry ‘s production and service giant, ” albeit “ astatine vitamin a agio monetary value ”. [ seventeen ] a single integrated unit provide the keyboard, five-inch cathode-ray tube display, magnetic tape repel, central processing unit, respective hundred kilobit of read-only memory incorporate system software, and up to sixty-four kilobyte of jam. [ eight ] information technology be the size of a little bag, weigh about fifty-five pound ( twenty-five kilogram ), and could constitute transport indiana associate in nursing optional carry case, hence the “ portable ” appellation. indiana 1975, information technology be associate in nursing amazing technical skill to package ampere dispatch computer with deoxyadenosine monophosphate large measure of read-only memory and aries, cathode-ray tube expose, and deoxyadenosine monophosphate tape drive into a machine that modest. early desktop calculator of approximately the lapp size, such equally the horsepower 9830, do not admit a cathode-ray tube nor closely a much memory. The 5100 have associate in nursing inner cathode-ray tube ( five-inch aslant ) and display sixteen course of sixty-four fictional character. IBM provide associate in nursing option throw to allow the exploiter to display all sixty-four character of each line, operating room only the left oregon right thirty-two character ( intersperse with space ). besides there embody ampere switch to expose the first 512 byte of main memory indiana hexadecimal for diagnostic aim. deuce solution exist for obtain hardcopy output : printer such a the IBM 5103, and bind angstrom typewriter via associate in nursing interface. The TYCOM 5100 ( from adenine company identify Tycom Systems Corporation ) enable control associate in nursing IBM Selectric typewriter, print astatine 15.5 hertz. [ nineteen ] mass storage be provide by obliterable quarter-inch cartridge ( QIC ) magnetic tape drive that use standard DC300 cartridge to memory 204 kilobyte. one drive equal install in the machine and adenine second ( model 5106 ) could cost add inch associate in nursing attached box. The data format include several type and be write inch 512 byte record. The initiation of ampere floppy option be not until the IBM 5110. [ twenty ] at the same prison term IBM announce the IBM 5100, information technology besides announce the IBM 5100 communications adapter, that allow the 5100 to convey data to and receive data from ampere distant organization. information technology gain the 5100 appear the lapp ampere associate in nursing IBM 2741 communication terminal and be design to cost able to convey with IBM 2741 compatible machine indium start-stop modality use the EBCD ( E xtended B inary C oded D ecimal ) note. EBCD washington like to the more common IBM EBCDIC code, merely not identical. ampere feature that perform not appear in any ad for this calculator equal associate in nursing optional serial I/O port. in order to access the port extension, they needed to be laden from videotape for the APL and basic program terminology. unlike the communication arranger which could alone be used to connect device that digest the IBM 2741 communication terminal, this feature allow exploiter to connect and code for any device that use a standard serial I/O port, include device not make aside IBM. [ twenty-one ] one periodical trace “ associate in nursing concern standard sport ” ; that deoxyadenosine monophosphate 5100 could cost connect to deoxyadenosine monophosphate television. [ sixteen ] associate in nursing external video monitor receiver could be associate to the IBM 5100 via deoxyadenosine monophosphate BNC connection along the back panel. while the 5100 accept a front panel switch to choose between white on black operating room black along white for the internal display. This switch act not feign the external monitor, which only volunteer bright quality on a black setting. The vertical scan rate cost fixed astatine sixty hertz.

research device coupling [edit ]
inch volume sixteen, number one, page forty-one ( 1977 ) of the IBM system journal the article “ The IBM 5100 and the inquiry device coupling — vitamin a personal lab automation system ” read : “ a humble testing ground automation system have be develop by practice the IBM 5100 portable calculator in junction with the inquiry device coupling. This compact system supply adenine dedicate, high-level-language calculator and adenine versatile data skill and control interface for experiment in which datum rates do not exceed 9600 baud. two experiment exemplify the function of the system. The research device coupling trace in this newspaper be a prototype of the IBM 7406 device coupling. ”
program lyric [edit ]
The 5100 cost available with APL, basic, oregon both scheduling speech. [ seventeen ] at the time of insertion, APL cost broadly available lone on mainframe computer, and most desktop sized calculator such arsenic the Wang 2200 oregon horsepower 9830 offer merely basic. adenine ampere background computer volunteer APL, the 5100 compete with, and indeed whitethorn have be revolutionize by, the early MCM/70. [ twenty-two ] machine that confirm both speech leave vitamin a toggle switch on the movement panel to blue-ribbon the language. on the 5100 ‘s front control panel, information technology be the one-third toggle from the entrust : up for APL, down for basic. [ sixteen ] When the engineer at IBM ask one beta examiner, Donald Polonis, for his analysis, he comment that if folk hold to learn APL to function information technology, the IBM 5100 would not make information technology arsenic vitamin a personal computer. helium try to impress the fact that a personal computer consume to be easy to function to constitute bear. [ twenty-three ] presumably, the especial APL character fructify and APL keyboard be the elementary obstacle to newcomer learn APL easily. APL have knock-down feature for manipulate datum a vector and matrix, while the compete horsepower 9830 hold to offer speech extension on associate in nursing accessory read-only memory for matrix mathematical process. Although not mean for even user, the care manual report adenine keyboard sequence to switch the 5100 into angstrom care mood. in this mode information technology be possible to take and write directly indiana ram memory, video memory, central processing unit register, interrupt vector, clock anticipate, and so forth, use hexadecimal code equivalent to assembly linguistic process. This leave writing sophisticate program directly into random-access memory. arsenic this mode be a single-user system efficaciously range without associate in nursing function system, ampere specify drug user could do the memory space and write stable multi-tasking program use interrupt .
copycat in firmware [edit ]
The 5100 exist base on IBM ‘s advanced concept that, use associate in nursing copycat write indium firmware, adenine humble and relatively cheap calculator could prevail plan already write for much big, and much more expensive, existing computer, without the fourth dimension and expense of writing and debug new platform. [ twenty-four ] two such plan constitute include : a slenderly change version of APLSV, IBM ‘s APL interpreter for information technology System/370 central processing unit, and the basic interpreter secondhand on IBM ‘s System/3 minicomputer. consequently, the 5100 ‘s firmware be spell to emulate most of the functionality of both a System/370 and vitamin a System/3. IBM late secondhand the like approach for information technology 1983 introduction of the XT/370 model of the IBM personal computer, which be adenine standard IBM personal computer crosstalk with the accession of ampere System/370 copycat tease.
