The '''Atari Portfolio''' ('''Atari PC Folio''') is an [[IBM PC-compatible]] [[palmtop PC]], released by [[Atari Corporation]] in June 1989. It was the first [[palmtop computer]] compatible with the [[IBM Personal Computer|IBM PC]] ever released.<ref name="Smith">{{cite web|url=https://www.theregister.co.uk/2007/06/07/forgotten_tech_atari_portfolio/ |title=Atari's Portfolio: the world's first palmtop|author= Smith, Tony|date= 7 June 2007|access-date = 30 November 2024|website= The A Register}}</ref>

==History==
[[DIP Research]] Ltd. based in [[Guildford]], [[Surrey]], UK released a product in the UK called the ''DIP Pocket PC'' in 1989. Soon after its release, DIP licensed this product to Atari for sale as the ''Portfolio'' in the UK and US.<ref name="DIP">[http://commons.wikimedia.org/wiki/File:100_4868.JPG Image of Original DIP Pocket PC]</ref> In Italy, Spain and Germany, it was originally marketed as ''PC Folio'' instead.<ref>{{cite web |url=http://www.atari-computermuseum.de/pics/scans/pcfolio_0289.pdf |title=Atari PC Folio |lang=de |type = product sheet}}</ref> DIP officially stood for "Distributed Information Processing", although secretly it actually stood for "David, Ian and Peter", the three founding members of the company who were former employees of [[Psion (computers)|Psion]].<ref name="DIP"/> The original founder of the company (first called "Crushproof Software") was [[Ian H. S. Cullimore]], and the other two David Frodsham and Peter Baldwin.<ref name="Smith"/> Cullimore was involved in designing the early Organiser products at Psion before the DIP Pocket PC project. The technologic successor of the Portfolio was the also DIP-developed [[Sharp PC-3000]]/[[Sharp PC-3100|3100]]. DIP Research was later acquired by [[Phoenix Technologies]] in 1994.<ref>{{cite web |title=Phoenix Technologies acquire DIP Research |author=<!--Staff writer(s); no by-line.--> |publisher=CBR |date=11 July 1994 |url=http://www.cbronline.com/news/phoenix_technologies_acquire_dip_research |access-date=6 February 2015}}</ref>

[[File:DIP Operating System 2.11.png|thumb|left|upright=1.2|DIP Operating System 2.11]]
The Portfolio uses an Intel [[Intel 8088|80C88]] CPU running at 4.9152&nbsp;MHz and runs "DIP Operating System 2.11" (DIP DOS), an [[operating system]] mostly compatible to [[MS-DOS 2.11]], but with some DOS 2.xx functionality lacking and some internal data [[structure]]s more compatible with DOS 3.xx. It has 128&nbsp;KB of RAM and 256&nbsp;KB of ROM which contains the OS and built-in applications. The on-board RAM is divided between system memory and local storage (the [[Drive_letter_assignment#Common_assignments|C: drive]]). The LCD is monochrome without [[backlight]] and has {{resx|240|64}} pixels or 40 characters × 8 lines.

The sound is handled by a small [[Dual-Tone Multi-Frequency]] speaker capable of outputting tones between 622 and 2,489Hz, the same range as touch-tone telephones, so users could not only use the address book app to store phone numbers, but actually speed-dial them too by holding the device up to a telephone handset.<ref>LGR: [https://www.youtube.com/watch?v=rQwJk8E_xKE Atari Portfolio – The $400 Palmtop PC from 1989], YouTube, 29 October 2021</ref>

Power is supplied by three AA size removable [[alkaline batteries]]. The computer's memory is preserved during battery changes. There is also an optional AC adapter (120{{nbsp}}V: HPC-401, 230{{nbsp}}V: HPC-402).<ref name="ABOUTPF">[http://www.atari-portfolio.co.uk/aboutpf/ta-aboutpf.html "About Atari Portfolio"] {{Webarchive|url=https://web.archive.org/web/20110904145511/http://www.atari-portfolio.co.uk/aboutpf/ta-aboutpf.html |date=4 September 2011 }}, ''atari-portfolio.co.uk''</ref>

There is an expansion port on the right side of the computer for parallel (HPC-101), serial (HPC-102), modem or [[MIDI]] expansion modules. It uses a [[Bee Card (game cartridge)|Bee Card]] expansion port for removable memory (aka Credit Card Memory or CCM), which is not compatible with [[PC card]] as it predated that standard. Expansion cards were available in sizes of 32&nbsp;KB (HPC-201), 64&nbsp;KB (HPC-202), and 128&nbsp;KB (HPC-203) initially, and later were available in capacities up to 4&nbsp;MB.<!-- HPC-204: OTPROM-card 512 KBit, HPC-205 OTPROM-card 1 MBit --> The expansion cards were backed up by a replaceable battery, which last approximately two years. Built-in applications include a [[text editor]], [[spreadsheet]] ([[Lotus 1-2-3]] compatible), phone book and time manager. Expansion cards contain programs such as a chess game (HPC-750), a [[file manager]] (HPC-704), and a finance manager (HPC-702). Most text-based DOS applications can run on the Portfolio as long as they did not directly access the hardware and could fit into the small memory.

Other expansion modules include a [[floppy drive]], and a memory expansion unit (HPC-104). The memory expansion unit gives the Portfolio an additional 256&nbsp;KB of RAM, which can be [[disk partitioning|partitioned]] into several drives. It also features a [[Passthrough (electronics)|pass-through]] expansion connector, allowing the use of more than one expansion unit. In theory, multiple memory expanders can be attached, increasing the available storage to over [[conventional memory|640&nbsp;KB]].

A card reader (HPC-301) connects to a desktop PC to read and write to the expansion cards. The kit contains an [[ISA card]], a special cable, the card reader, and software distributed on floppy disk.

A modem expansion module converts the portfolio into a miniature [[computer terminal]]. The modem is powered from the portfolio and came with an [[acoustic coupler]] consisting of two round shells that could be mounted over both ends of a handset with the aid of [[velcro]] strips. A direct connection to a telephone with a standard telephone lead is also possible. The complete terminal and coupler are portable, weighing only a few hundred grams.<ref>[http://www.old-computers.com/museum/hardware.asp?t=1&c=356&st=1 page with a picture of the modem expansion module]</ref>

Also, using the [[parallel port]] expansion module (HPC-101), a standard parallel cable and the software supplied (DOS-based), the Portfolio can be connected to a PC for transferring files to and from the unit.

Credits for the development of the product can be found in an [[Easter egg (media)|easter egg]] if one selects Setup, then Help, and then presses {{keypress|Alt}}+{{keypress|[}} ("Alt" plus "left square [[bracket]]").
