A Palmtop PC is an obsolete, approximately pocket calculator-sized, battery-powered computer in a horizontal clamshell design with integrated keyboard and display. It could be used like a modern 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 have been 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.[1]

The Sharp PC-3000 was an MS-DOS-based palmtop computer introduced in late 1991 and shipped in volume in 1992. The "SPC" was designed and developed by DIP Research Ltd. ("DIP") in the UK. DIP had earlier designed the Atari Portfolio and the two machines shared many design features both in hardware and software.
This article details versions of MS-DOS, IBM PC DOS, and at least partially compatible disk operating systems. It does not include the many other operating systems called "DOS" which are unrelated to IBM PC compatibles.
This article presents a timeline of events in the history of 16-bit x86 DOS-family disk operating systems from 1980 to present. Non-x86 operating systems named "DOS" are not part of the scope of this timeline. Also presented is a timeline of events in the history of the 8-bit 8080-based and 16-bit x86-based CP/M operating systems from 1974 to 2014, as well as the hardware and software developments from 1973 to 1995 which formed the foundation for the initial version and subsequent enhanced versions of these operating systems. DOS releases have been in the forms of: OEM adaptation kits (OAKs) – all Microsoft releases before version 3.2 were OAKs only Shrink wrap packaged product for smaller OEMs (system builders) – starting with MS-DOS 3.2 in 1986,Microsoft offered these in addition to OAKs End-user retail – all versions of IBM PC DOS (and other OEM-adapted versions) were sold to end users.DR-DOS began selling to end users with version 5.0 in July 1990, followed by MS-DOS 5.0 in June 1991 Free download – starting with OpenDOS 7.01 in 1997, followed by FreeDOS alpha 0.05 in 1998(FreeDOS project was announced in 1994)
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
