  IBM 5100 - Wikipedia, the free encyclopedia
While the IBM 5100 seems large today, in 1975 it was an amazing technical accomplishment to package a complete computer with a large amount of ROM and RAM, CRT display, and a tape drive into a machine that small.
IBM later used the same approach for its 1983 introduction of the XT/370 model of the IBM PC, which was a standard IBM PC XT with the addition of a System/370 emulator card.
When the IBM PC was introduced in 1981, it was originally designated as the IBM 5150, putting it in the "5100" series, though its architecture wasn't directly descended from the IBM 5100.

The IBM 5100 Portable Computer was a desktop computer introduced in September 1975, six years before the (Click link for more info and facts about IBM PC) IBM PC.
The IBM 5100 is based on a 16-bit (Someone who processes things (foods or photographs or applicants etc.)) processor module called (Any plant of the family Palmae having an unbranched trunk crowned by large pinnate or palmate leaves) PALM (Put All Logic in Microcode).
It made the 5100 appear the same as an IBM 2741 Communications (Station where transport vehicles load or unload passengers or goods) Terminal and in theory was able to communicate with IBM 2741 compatible machines in start-stop mode using the EBCD (Extended Binary Coded Decimal) notation.

 IBM 5100
IBM, deciding it might be a Good Thing to actually try to sell more than ''six computers worldwide'', started a design campaign that lead to the IBM PC (and the doom of home computing, for that matter -- but that's another story).
IBM's interpretation of these concepts made the machine weigh in at 25 kilograms (50 pounds), while the price was a bit higher than your average businessman could afford ($14000 - $15000).
The model number 5100 indicates that it is indeed the forerunner of the IBM PC (model 5150) and PC XT (model 5160) and all the ones that followed.

The little-known IBM 5100 portable computer was released in 1975, six years before the Model 5150 even though the later is often regarded as the first IBM-PC.
The Model 5100 used a proprietary IBM processor called the PALM (for Put All Logic in Microcode) which itself was a production version of a prototype processor called SCAMP (for Special Computer APL Machine Portable) developed by Paul J. Friedl at the IBM Palo Alto Scientific Center in 1974.
The 5100 shipped with 16K to 64K of memory, used a tape drive for program storage, and depending on configuration the machine sold for $8,975 to $19,975.

John claimed he was related to one of the IBM engineers or programmers who worked on the 5100 and that's why he was chosen for this mission.
In 2036, it was discovered (or at least known after testing) that the 5100 computer was capable of reading and changing all of the legacy code written by IBM before the release of that system and still be able to create new code in APL and basic.
The 5100 had a very simple and unique feature that IBM did not account for and decided it was not in their best interest to advertise (which in hindsight was not very smart).

There were very few other computers available at the time, and nothing even close to the capabilities of the 5100.
Apparently, APL was a difficult task for IBM to accomplish with an interpreter in the 5100, so instead they wrote an emulation program so that the S/360 mainframe version of APL could be run instead -- The 5100 is like a desktop IBM S/360 mainframe computer which only runs APL.

Although IBM's launch of the Personal Computer (IBM 5150) in 1981 set the industry standard for personal computing, IBM had introduced a variety of small computers for individual users several years before that.
So while now is certainly an appropriate moment to salute the legendary IBM PC on its 20th birthday, it's also a good time to take a brief look back at some of the pioneering IBM products that immediately preceded it.
One of the earliest IBM attempts to move computing into the hands of single users was the "SCAMP" project in 1973.

According to Bob Dubke, the second engineer on IBM's 5100 team in Rochester (who now co-owns a locally-based company called eXport Ventures Corp. and also works for Edina Realty), that secret function was his contribution to the design of the computer.
The function, which IBM suppressed because of worries about how their competition might use it, was an interface between the assembly code surrounding the computer's ROM exterior, and the 360 emulator hidden beneath it.
(IBM declined to comment for this story.) The 5100's emulator gave programmers access to the functions of the monstrous, and much less portable machines, that IBM had produced during the 1960s.

 A Look Back at the IBM PC
According to IBM officials, the IBM PC was the first to use off-the-shelf components, which came back to haunt the company when the first IBM PC clones started appearing on the market.
Because the IBM PCs used readily available components, it was easy for competing PC builders to make their own machines and reverse-engineer the BIOS (define).
The $3,000 IBM 5150 ran on a 4.77 MHz 8088 Intel processor, had 16KB of RAM (upgradeable to 256KB) and came bundled with Microsoft's BASIC and with what was quickly termed the "killer app" for the PC, the 27KB-sized VisiCalc electronic spreadsheet (though VisiCalc v1.37 had been around since October 1979).
