/ref> In Italy, Spain and Germany, it was originally marketed as ''PC Folio'' instead. 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. The original founder of the company (first called "Crushproof Software") was Ian H. S. Cullimore, and the other two David Frodsham and Peter Baldwin. 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/ 3100. DIP Research was later acquired by

Technology

The Portfolio uses an Intel 80C88 CPU running at 4.9152 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 structures more compatible with DOS 3.xx. It has 128 KB of RAM and 256 KB of ROM which contains the OS and built-in applications. The on-board RAM is divided between system memory and local storage (the C: drive). The LCD is monochrome without backlight and has 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. 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 (120V: HPC-401, 230V: HPC-402)."About Atari Portfolio"

The expansion cards were backed up by a replaceable battery, which last approximately two years. Built-in applications include a text editor, spreadsheet (

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 KB of RAM, which can be partitioned into several drives. It also features a 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 640 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
