'''Ian H. S. Cullimore''' is an English-born mathematician and computer scientist who has been influential in the [pocket PC](/source/pocket_PC) arena.<ref name="NYT_1989"/>

==Biography==
Cullimore has a degree in [mathematics](/source/mathematics) from [King's College London](/source/King's_College_London), and a [PhD](/source/PhD) in [cognitive](/source/cognitive) and [computer science](/source/computer_science) from the [University of Sussex](/source/University_of_Sussex).

He was the original founder (in 1985) and main inventor of the pocket PC which became the [Atari Portfolio](/source/Atari_Portfolio) (originally known as the "DIP Pocket PC") in 1989. [DIP Research](/source/DIP_Research) Ltd. was acquired by [Phoenix Technologies](/source/Phoenix_Technologies) in 1994.<ref name="CBR_1994"/>

In 1988 Cullimore was also one of the founders and Vice President of Software at [Poqet Computer Corporation](/source/Poqet_Computer_Corporation) in [Silicon Valley](/source/Silicon_Valley), where he developed the [Poqet PC](/source/Poqet_PC).

His interest in PDAs was sparked from his early times at [Psion](/source/Psion_(computers)), working on the first Organiser products.

He was also the original instigator of the [PC Card](/source/PC_Card) (formerly "PCMCIA Card") movement. This came about from his decision to use the then-emerging credit card memories in the design of the Atari Portfolio. On founding Poqet, and with major investment from Fujitsu, a decision was made to use the 68-pin JEIDA card. He successfully persuaded the board of Poqet to set up an industry standards organization, [PCMCIA](/source/Personal_Computer_Memory_Card_International_Association), to promote this as a standard.

Cullimore wrote parts of the PCMCIA driver stack for (NetWare) [PalmDOS 1.0](/source/PalmDOS_1.0), a variant of Digital Research's [DR DOS](/source/DR_DOS), tailored specifically at battery powered mobile PCs in 1992.<ref name="IC_2015_CV"/>
