The Poqet PC is a very small, portable IBM PC compatible computer, introduced in 1989, for $2000 by Poqet Computer Corporation, but is no longer sold, since Fujitsu Ltd. bought Poqet Computer Corp. It was the first subnotebook form factor IBM-PC compatible computer that ran MS-DOS. The Poqet PC is powered by two AA-size batteries, through the use of aggressive power management, which included stopping the CPU between keystrokes, the batteries are able to power the computer for anywhere between a couple of weeks and a couple of months, depending on usage, and uses an "instant on" feature so that when you power down you don't need to go through a booting sequence, it just starts you right were you left off. The Poqet PC is comparable to the HP-95/HP-100/HP-200LX and the Atari Portfolio handheld computers. Even today the Poqet series devices are very versatile and useful as a notebook.

[edit] Poqet PC "Classic", and Prime

There were three variants of The Poqet PC. The Poqet PC was the first to be introduced, with the Poqet PC Prime following shortly after. After the Prime it was to be called the Poqet PC had "Classic" added to its name. Several years later, the Poqet PC Plus was introduced. The main difference between the Poqet PC Classic and the Prime was the expansion of RAM from 512 KB to 640 KB and the enhancement of the power management features.

[edit] Poqet PC Plus

Poqet PC Plus
Poqet PC Plus

Several years after the Poqet Prime and Classic, and some time after Fujitsu purchased Poqet Computer Corp., the new and improved Poqet PC Plus was introduced. The Poqet PC Plus had significant differences from the Classic and Prime models, some better than others. It features a rechargeable battery pack that holds a smaller charge than the "Classic", enhanced PC card slots that now supports more PC cards, a transflective backlit LCD and 2 MB of RAM, with 640k to DOS, 64k shadow, and 1-1344k for a RAM disk. The Poqet "Classic"'s LCD didn't have a backlight and was more prone to breaking than the Poqet PC Plus. It also only took Type I, Release 1.0 SRAM cards, as opposed to Type II cards and Release 2.0 cards, which included flash, SRAM, and a few modem cards. The Plus also had more memory. Despite many improvements, the Plus also had its drawbacks. The Poqet PC Plus was considerably larger and heavier than its predecessors. It weighed approximately 1.83 lb as opposed to the Classic's 1.2 lb. It also has a very odd miniature 26-pin serial connector for which there is no currently available adaptor. However, many Toshiba external floppy drives and dongles used this same JAE connector. An amateur radio hobbyist who uses a Poqet has found a way to make a good adapter. It also is not totally PCMCIA Release 2.0 compatible, so not all memory cards will work, and, as Bryan Mason says on his Poqet site, only the "PNB Samantha modem, Megahertz 14.4 kbit/s modem with XJACK, and the AT&T Paradyne KeepInTouch 14.4 kbit/s modems" will work in it. In addition, not all CompactFlash cards work in the Poqet. Users have found that many machines do not work with newer CF cards.

This is also the only Poqet Computer that is available for direct purchase (other than from the online auction site eBay). California Digital sells the Plus for $160 (for the Poqet only) and $170 if you buy a 2 MB PCMCIA Memory card as well. This seems to be the best deal as the memory cards are $60 alone from CA Digital. The Poqet PC Plus was produced in very small quatities, and so it is very rare, despite current availability from CA Digital. CA Digital purchased their stock from the R. J. Reynolds Tobacco Company which had their sales force use it, according to an online review of the PC Plus by Al Wong. Al Wong, a Los Angeles, California resident, became a PC Plus owner in April of 1999 (Wong). Also, according to Wong, California Digital Pluses come with a small, detachable plastic housing with a standard, DB9 serial connector. RJ Reynolds was one of the few customers of Poqet and later Fujitsu (Wong). In all, there were probably fewer than 3,000 PC Pluses, as a possible estimate.

The Poqet PC was one of the first subnotebooks to exist in the marketplace, and still today is one of the smallest, although it is beaten by the HP-200LX. It was immediately recognized as a milestone in portable computing when PC Magazine awarded the Poqet PC development team (Ian Cullimore, John Fairbanks, Leroy Harper, Shinpei Ichikawa, Stav Prodromou) its coveted Technical Excellence Award for 1989. Interestingly, the same device that PC World called "one of the 50 greatest gadgets of the last 50 years" had a very short lifespan, from only about 1989 to 1994. After Poqet was bought by Fujitsu, the Poqet was soon axed. For a short time Poqet value declined, with the onset of Windows CE. A similar decline in HP 200LX demand also occurred after the introduction of HP Windows CE machines. However, despite the new machines' power, their operating system soon proved to be inefficient. The Poqets and HP 'LX' DOS machines became very high in demand, and recently an HP 200LX sold for $182 on eBay. Poqets also are in fairly high demand, but fetch somewhat lower prices. A Cherry Hill, NJ business, Disks 'n' Data, once had a stock of Classics and Pluses. As the owner of the store, Jerry Tessler, put it: "I sold them all in twenty minutes." Unlike running WinCE, running DOS in near-standard specifications meant that everything from Lotus 123 to Zork.
