The 200LX, a popular Palmtop PC from Hewlett-Packard

A Palmtop PC was an approximately pocket calculator-sized, battery-powered computer compatible with the IBM Personal Computer in a horizontal clamshell design with integrated keyboard and display. It could be used like a subnotebook, but was light enough to be comfortably used handheld as well. Most Palmtop PCs were small enough to be stored in a user's shirt or jacket pockets.

Palmtop PCs distinguish from other palmtop computers by using a mostly IBM-compatible PC architecture and BIOS as well as an Intel-compatible x86 processor. All such devices were DOS-based, with DOS stored in ROM. While many Palmtop PCs came with a number of PDA and office applications pre-installed in ROM, most of them could also run generic, off-the-shelf PC software with no or little modifications. Some could also run other operating systems such as GEOS, Windows 1.0-3.0 (in Real mode only), or MINIX 2.0.

Most Palmtop PCs were based on a static hardware design for low power consumption and instant-on/off without the need to reboot. Depending on the model, the battery could power the device for a period ranging from several hours up to several days while running, or between a week and a year in standby mode. Combined with the instant-on/off feature, a battery would typically last from a week up to several months in practical use as PDA.

The first Palmtop PC was the DIP Pocket PC (aka Atari Portfolio) in 1989.

A Pocket PC is a class of personal digital assistant (PDA) that runs the Windows Mobile or Windows Embedded Compact operating system that has some of the abilities of modern desktop PCs. The name was introduced by Microsoft in 2000 as a rebranding of the Palm-size PC category. Some of these devices also had integrated phone and data capabilities, which were called Pocket PC Phone Edition. Windows "Smartphone" is another Windows CE based platform for non-touch flip phones or dumber phones.

The Poqet PC is a very small, portable IBM PC compatible computer, introduced in 1989 by Poqet Computer Corporation with a price of $2000. The computer was discontinued after 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 includes 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. The computer also uses an "instant on" feature, such that after powering it down, it can be used again immediately without having to go through a full booting sequence. The Poqet PC is comparable to the HP 95LX/HP 100LX/HP 200LX and the Atari Portfolio handheld computers.

HP-150 was a compact, powerful and innovative computer made by Hewlett-Packard in 1983. It was based on the Intel 8088 CPU and was one of the world's earliest commercialized touch screen computers. Like other "workalike" IBM PC clones of the time, despite running customized MS-DOS versions 2.01, 2.11 and 3.20, the machine was not IBM PC DOS compatible. Its 8088 CPU, rated at 8 MHz, was faster than the 4.77 MHz CPUs used by the IBM PC of that period. Using add-on cards, main memory could be increased from 256 KB to 640 KB. However, its mainboard did not have a slot for the optional Intel 8087 math coprocessor due to space constraints. An HP-150 with an optional hard disk was called HP Touchscreen MAX.

In computing, a hardware code page (HWCP) refers to a code page supported natively by a hardware device such as a display adapter or printer. The glyphs to present the characters are stored in the alphanumeric character generator's resident read-only memory and are thus not user-changeable. They are available for use by the system without having to load any font definitions into the device first. Startup messages issued by a PC's System BIOS or displayed by an operating system before initializing its own code page switching logic and font management and before switching to graphics mode are displayed in a computer's default hardware code page.

The Sharp PC-3000 was an MS-DOS-based palmtop computer introduced in 1991. The "SPC" was designed and developed by Distributed Information Processing Research Ltd. ("DIP") in the UK.
