HP OmniBook was a range of laptop personal computers created by Hewlett-Packard, introduced in 1993. The range was discontinued following the acquisition of Compaq by Hewlett-Packard in 2002, with the Compaq Presario, HP Compaq, and HP Pavilion laptops succeeding the OmniBook line.
The HP OmniBook 300 (OB300) is a "superportable" laptop released in 1993 as one of the first notebook computers in the OmniBook line. It weighed only 2.9 pounds and measured 1.4 × 6.4 × 11.1 inches. It is powered by an Intel 386SXLV processor, featured a full-size keyboard, a pop-up mouse (The same pop-up mouse was also used in Omnibook 800CT), and a 9-inch VGA screen. Due to storage limitations, the OmniBook 300 included both Microsoft Excel and Microsoft Word pre-installed in ROM, which was and still remains unusual to this day. It had two PCMCIA slots for additional memory, modem, network cards or other peripherals. One of its outstanding features was a technology known as "Instant On". It was sold in three storage configurations: no mass storage (F1030A at US$1,515), 10MB flash memory disk (F1031A at US$2,375), or 40MB hard drive (F1032A at US$1,950). Compared to the hard drive, the flash memory disk reduced the weight and storage capacity but increased battery life. It came with slimmed-down copies of MS-DOS 5.0 and Windows 3.1. The "International English" version of the OmniBook 300 used code page 850 (rather than the more common code page 437) as hardware code page.
