This IP address has been blocked from editing Wikipedia.
This does not affect your ability to read Wikipedia pages.
Most people who see this message have done nothing wrong. Some kinds of blocks restrict editing from specific service providers or telecom companies in response to recent abuse or vandalism, and can sometimes affect other users who are unrelated to that abuse. Review the information below for assistance if you do not believe that you have done anything wrong.

The IP address or range 54.163.0.0/16 has been blocked (disabled) by ‪Blablubbs‬ for the following reason(s):

The IP address that you are currently using has been blocked because it is believed to be a web host provider or colocation provider. To prevent abuse, web hosts and colocation providers may be blocked from editing Wikipedia.
You will not be able to edit Wikipedia using a web host or colocation provider because it hides your IP address, much like a proxy or VPN.
We recommend that you attempt to use another connection to edit. For example, if you use a proxy or VPN to connect to the internet, turn it off when editing Wikipedia. If you edit using a mobile connection, try using a Wi-Fi connection, and vice versa. If you are using a corporate internet connection, switch to a different Wi-Fi network. If you have a Wikipedia account, please log in.
If you do not have any other way to edit Wikipedia, you will need to request an IP block exemption.

How to appeal if you are confident that your connection does not use a colocation provider's IP address:
If you are confident that you are not using a web host, you may appeal this block by adding the following text on your talk page: ((unblock|reason=Caught by a colocation web host block but this host or IP is not a web host. My IP address is _______. Place any further information here. ~~~~)). You must fill in the blank with your IP address for this block to be investigated. Your IP address can be determined here. Alternatively, if you wish to keep your IP address private you can use the unblock ticket request system. There are several reasons you might be editing using the IP address of a web host or colocation provider (such as if you are using VPN software or a business network); please use this method of appeal only if you think your IP address is in fact not a web host or colocation provider.

Administrators: The IP block exemption user right should only be applied to allow users to edit using web host in exceptional circumstances, and requests should usually be directed to the functionaries team via email. If you intend to give the IPBE user right, a CheckUser needs to take a look at the account. This can be requested most easily at SPI Quick Checkuser Requests. Unblocking an IP or IP range with this template is highly discouraged without at least contacting the blocking administrator.

This block will expire on 17:28, 10 March 2024.

Even when blocked, you will usually still be able to edit your user talk page, as well as email administrators and other editors.

Portable computers, more narrowly defined, are distinct from [[desktop replacement computer]]s in that they usually were constructed from full-specification desktop components, and often do not incorporate features associated with laptops or mobile devices. A portable computer in this usage, versus a laptop or other [[mobile computing]] [[mobile device|device]], have a standard [[motherboard]] or [[backplane]] providing plug-in slots for add-in cards. This allows mission specific cards such as test, A/D, or communication protocol (IEEE-488, 1553) to be installed. Portable computers also provide for more disk storage by using standard disk drives and provide for multiple drives.

==Early history==
===SCAMP===
In 1973, the [[IBM]] Los Gatos Scientific Center developed a portable computer prototype called SCAMP (Special Computer APL Machine Portable) based on the [[IBM PALM processor]] with a [[Philips]] compact cassette drive, small [[Cathode ray tube|CRT]] and full function keyboard. SCAMP emulated an [[IBM 1130]] minicomputer in order to run APL\1130.<ref>((cite web|last=Freeman |first=Shanna |url=http://computer.howstuffworks.com/first-portable-computer.htm |title=HowStuffWorks "What was the first portable computer?" |publisher=Computer.howstuffworks.com |date=2012-09-19 |access-date=2014-07-22))</ref> In 1973, [[APL (programming language)|APL]] was generally available only on mainframe computers, and most desktop sized microcomputers such as the [[Wang 2200]] or [[HP 9800 series|HP 9800]] offered only [[BASIC]]. Because SCAMP was the first to emulate APL\1130 performance on a portable, single user computer, ''PC Magazine'' in 1983 designated SCAMP a "revolutionary concept" and "the world's first personal computer".<ref>''PC Magazine'', Vol. 2, No. 6, November 1983, ‘’SCAMP: The Missing Like in the PC's Past?‘’</ref><ref>((cite web|url=http://www-03.ibm.com/ibm/history/exhibits/pc/pc_2.html |title=IBM Archives: IBM 5100 Portable Computer |date=23 January 2003 |publisher=03.ibm.com |access-date=2014-07-22))</ref> The engineering prototype is in the [[Smithsonian Institution]].<ref>((cite web|url= http://www.si.edu/object/nmah_334628 |title= IBM SCAMP, National Museum of American History | publisher= Smithsonian Institution |date= |access-date= 2023-02-15))</ref>

===Xerox NoteTaker===
[[Xerox NoteTaker]], developed in 1976 at [[Xerox PARC]], was a precursor to later portable computers from [[Osborne Computer Corporation]] and [[Compaq]], though it remained a prototype and did not enter production.

===IBM 5100===
[[File:IBM 5100 - MfK Bern.jpg|thumb|IBM 5100 (1975)]]
Successful demonstrations of the 1973 SCAMP prototype led to the first commercial [[IBM 5100]] portable microcomputer launched in 1975. The product incorporated an [[IBM PALM processor]], ((convert|5|in|adj=on)) [[Cathode ray tube|CRT]], full function keyboard and the ability to be programmed in both APL and BASIC for engineers, analysts, statisticians and other business problem-solvers. (IBM provided different models of the 5100 supporting only BASIC, only APL, or both selectable by a physical switch on the front panel.)<ref>This author learned this from an original IBM document for operators of the 5100 but does not recall the title of the document.</ref><ref>((Cite web |url=http://www.classiccmp.org/dunfield/ibm5100/index.htm |title=Daves Old Computers- IBM 5100 |access-date=2019-03-08 |archive-url=https://web.archive.org/web/20071126062928/http://www.classiccmp.org/dunfield/ibm5100/index.htm |archive-date=2007-11-26 |url-status=dead ))</ref> [[IBM]] referred to its [[IBM PALM processor|PALM]] processor as a [[microprocessor]], though they used that term to mean a processor that executes [[microcode]] to implement a higher-level [[instruction set]], rather than its conventional definition of a complete processor on a single [[silicon]] [[integrated circuit]]; the PALM processor was a large circuit board populated with over a dozen chips. In the late 1960s, such a machine would have been nearly as large as two desks and would have weighed about half a ton (((convert|0.5|ST|disp=out))). In comparison, the IBM 5100 weighed about 53 pounds (24&nbsp;kg and very portable for that time).<ref>((cite web|url=http://www.advantech.com/products/Portable-Computers/sub_1-2JKOHS.aspx |title=Industrial Portable Computers |publisher=Advantech |access-date=2014-07-22))</ref>

===MIT Suitcase Computer===
The MIT Suitcase Computer, constructed in 1975, was the first known microprocessor-based portable computer.  It was based on the [[Motorola 6800]].  Constructed in a Samsonite suitcase approximately ((convert|20x30x8|in)) and weighing approximately ((convert|20|lb|abbr=on)), it had 4K of SRAM, a serial port to accept downloaded software and connect to a modem, a keyboard and a 40-column thermal printer taken from a cash register.  Built by student David Emberson in the MIT Digital Systems Laboratory as a thesis project, it never entered production.  It is currently in the collection of Dr. Hoo-Min D. Toong.((citation needed|date=May 2015))

===Micro Star or Small One===
An early portable computer was manufactured in 1979 by GM Research,<ref>((Cite web |url=http://www.computerhistory.org/collections/accession/X1243.96 |title=Computer History Museum |access-date=2008-12-10 |archive-url=https://web.archive.org/web/20130523011552/http://www.computerhistory.org/collections/accession/X1243.96 |archive-date=2013-05-23 |url-status=dead ))</ref> a small company in Santa Monica, California. The machine which was designed and [http://www.google.com.ar/patents/US4294496 patented] by James Murez. It was called the Micro Star and later the name was changed to The Small One. Although Xerox claims to have designed the first such system, the machine by Murez predated anything on the market or that had been documented in any publication at the time((snd)) hence the patent was issued. As early as 1979, the U.S. Government was contracting to purchase these machines. Other major customers included Sandia Labs, General Dynamics, BBN (featured on the cover of their annual report in 1980 as the C.A.T. system) and several dozen private individuals and companies around the world. In 1979, [[Adam Osborne]] viewed the machine along with several hundred other visitors at the first computer show that was sponsored by the IEEE Westec in Los Angeles.  Later that year the machine was also shown at the first [[COMDEX]] show.

===Portal R2E CCMC===
[[File:Micro ordinateur portable le PORTAL de R2E CCMC.jpg|thumb|R2E CCMC [[Portal (computer)|Portal]] laptop in September 1980 at the SICOB show in PARIS]]

The portable micro computer; the "[[Portal (computer)|Portal]]" of the French company R2E [[Micral]] CCMC officially appeared in September 1980 at the Sicob show in Paris. The Portal was a portable microcomputer designed and marketed by the studies and developments department of the French firm R2E Micral in 1980 at the request of the company CCMC specializing in payroll and accounting. The Portal was based on an intel 8085 processor, 8-bit, clocked at 2&nbsp;MHz. It was equipped with a central 64&nbsp;KB RAM, a keyboard with 58 alpha numeric keys and 11 numeric keys (separate blocks), a 32-character screen, a floppy disk: capacity = 140 000 characters, of a thermal printer: speed = 28 characters / sec, an asynchronous channel, a synchronous channel, a 220&nbsp;V power supply. Designed for an operating temperature of ((convert|15-35|C)), it weighed ((convert|12|kg)) and its dimensions were ((convert|45|x|45|x|15|cm|abbr=on)). It provided total mobility. Its operating system was [[Prolog]].  A few hundred were sold between 1980 and 1983.

===Osborne 1===
[[File:Osborne 1 open.jpg|thumb|Osborne 1 (1981)]]
The first mass-produced microprocessor-based portable computer released in 1981 was the [[Osborne 1]], developed by Osborne, which owed much to the NoteTaker's design. The company had early success with the design and went public but later due to small screen sizes and other devices being released found trouble selling the Osborne.<ref name=oldcomputer>((cite web|url=http://oldcomputers.net/osborne.html |title=Osborne 1|publisher=OldComputers.net|access-date=May 21, 2010))</ref> The Osborne 1 is about the size and weight of a sewing machine, and was advertised as the only computer that would fit underneath an [[airline seat]].<ref name=atlantic>((cite web|url=https://www.theatlantic.com/doc/198207/fallows-computer/2 |title=Living With a Computer|first=James|last=Fallows |date=July 1982 |publisher=Atlantic Magazine |access-date=May 21, 2010))</ref>

===Kaypro===
Another early portable computer released in 1982 was named the [[Kaypro II]], although it was the company's first commercially available product. Some of the press mocked its design—one magazine described [[Kaypro Corporation]] as "producing computers packaged in tin cans".<ref name="dickinson198607">((cite news | url=https://books.google.com/books?id=5hdeC0k_JHwC&pg=PA116 | title=Kaypro 2000 | work=PC | date=July 1986 | access-date=9 January 2015 | author=Dickinson, John | pages=116))</ref>  Others raved about its value, as the company advertised the Kaypro II as "the ((US$|long=no|1595)) computer that sells for ((US$|long=no|1595))",<ref name="kaypro198401">((cite news | url=https://archive.org/stream/byte-magazine-1984-01/BYTE-1984-01#page/n395/mode/2up | title=The ((US$|long=no|1595)) Computer That Sells for ((US$|long=no|1595)). | work=BYTE | date=January 1984 | access-date=20 January 2015 | pages=390 | type=advertisement))</ref> some noting that the included software bundle had a retail value over ((US$|long=no|1000)) by itself, and by mid-1983 the company was selling more than 10,000 units a month, briefly making it the fifth-largest computer maker in the world. It managed to correct most of the [[Osborne 1]]'s deficiencies: the screen was larger and showed more characters at once, the floppy drives stored over twice as much data, the case was more attractive-looking, and it was also much better-built and more reliable.

===Grid Compass===
[[File:Macintosh Portable-IMG 7541.jpg|thumb|Macintosh Portable (1989)]]
[[File:GRiD Compass 1101 (1).jpg|thumb|Grid Compass (1982)]]
The [[Grid Compass]] ran its own operating system, GRiD-OS. Its specialized software and high price (US$8,000–10,000) meant that it was limited to specialized applications. The main buyer was the U.S. government. NASA used it on the Space Shuttle during the early 1980s, as it was powerful, lightweight, and compact. The military Special Forces also purchased the machine, as it could be used by paratroopers in combat.<ref>((Cite web|last=didyouknowwebsite|date=2020-06-14|title=The Space Age Best Inventions We use Today|url=https://didyouknowwebsite.com/2020/06/14/the-space-age-best-inventions-we-use-today/|access-date=2020-06-14|website=Did You Know?|language=en-US))</ref>

==Post-IBM PC portables==
===Compaq Portable and competitors===
Although [[Columbia Data Product]]'s MPC 1600, "Multi Personal Computer" came out in June 1983,<ref>[https://books.google.com/books?id=14Kfbrc6cbAC&pg=PA451 "Aboard the Columbia"], By Bill Machrone, Page 451, Jun 1983, ''PC Mag''</ref><ref>((Cite web|url=https://www.computerhistory.org/revolution/personal-computers/17/302/1188|title = Columbia personal computer - CHM Revolution))</ref> one of the first extensively [[IBM PC compatible]] computers was the [[Compaq Portable]].

They settled and were forced to halt production. Neither the Columbia nor the Eagle were nearly as [[IBM PC DOS]] compatible as Compaq's offerings.

===Commodore SX-64===
The first full-color portable computer was the [[Commodore SX-64]] in January 1984..

=== Atari STacy ===
Originally announced in 1987, the [[Atari STacy]] was released to the public in December 1989 and was one of the first laptop-like portables.<ref>((Cite web|title=Atari Stacy 2 - Computer - Computing History|url=http://www.computinghistory.org.uk/det/43435/Atari-Stacy-2/|access-date=2021-04-27|website=www.computinghistory.org.uk))</ref><ref>((Cite web|last=ausretrogamer|date=2016-04-06|title=The Lovely Atari STacy ((!))

===Apple Macintosh Portable===
[[Apple Inc.]] introduced and released the [[Macintosh Portable]] in 1989, though this device came with a battery, which added to its substantial weight.  The Portable has features similar to the [[Atari STacy]], include integrated trackball and clamshell case.

=== IBM PS/2 Portable ===
After release of [[IBM PC Convertible]] in 1986, IBM still produced classic portable computers, include released in 1989 [[PS/2|PS/2 P70]] (with upgrade in 1990 to [[IBM P75|P75]]), and IBM produce portables for up to release of [[IBM PS/2 Note|PS/2 Note]] and [[PS/55note]] notebook lines.
