This is a page about the Palm-PDA. Wikipedia writes: Palm handhelds were Personal Digital Assistants (PDAs) that ran the Palm OS. The Palm TX offers the ability to browse the Internet wirelessly. On 28 April 2010 it was announced that Hewlett-Packard would acquire Palm for around US$1.2 billion. Although HP kept the Palm brand initially, all new PDA devices announced at press announcement on February 9, 2011, were branded as HP devices, not as Palm devices. TCL Corporation announced in January 2015 that it had acquired Palm's intellectual property from HP at the end of 2014, announcing plans to restart the company with crowdfunding being a key element in the development of new Palm smartphones. Pilot was the name of the first generation of personal digital assistants manufactured by Palm Computing in 1996 (by then a division of U.S. Robotics).
The inventors of the Pilot were Jeff Hawkins, Donna Dubinsky, and Ed Colligan, who founded Palm Computing in 1992. The original purpose of this company was to create handwriting recognition software, named PalmPrint, and personal information management (PIM) software, named PalmOrganizer for the PEN/GEOS based Zoomer devices. Their research convinced them, however, they could create better hardware as well. Before starting development of the Pilot, Hawkins said he carried a block of wood, the size of the potential Pilot, in his pocket for a week. Palm was widely perceived to have benefited from the notable if ill-fated earlier attempts to create a popular handheld computing platform by Go Corporation, Tandy, and Apple Computer (Newton). The prototype for the first Palm Connected Organizer was called "Palm Taxi". The first two generations of PDAs from Palm were referred to as "Palm-Pilots". Due to a trademark infringement lawsuit brought by the Pilot Pen Corporation, since 1998 handheld devices from Palm have been known as Palm Connected Organizers or more commonly as "Palms".
The first Palms, the Pilot 1000 and Pilot 5000, had no infrared port, backlight, or flash memory, but did have a serial communications port. Their RAM size was 128 kB and 512 kB respectively, and they used version 1 of Palm OS. Later, it became possible to upgrade the Pilot 1000 or 5000's internals to up to 1 MB of internal RAM. This was done with the purchase of an upgrade module sold by Palm, and the replacement of some internal hardware components. Originally, it was conceived that all Palm PDAs were to be hardware-upgradable to an extent, but ultimately, this capability gave way to external memory slots and firmware-upgradable flash memory after the Palm III series.
The next couple of Palms, the PalmPilot Personal and PalmPilot Professional, had backlit screens, but no infrared port or flash memory. Their RAM size was 512 kB and 1024 kB respectively. They used version 2 of the Palm OS. Palm III, and all the following Palms, did not have the word "Pilot" in their name due to the previously mentioned trademark dispute. The Palm III had an IR port, backlight, and flash memory. The latter allowed the user to upgrade Palm OS, or, with some external applications, to store programs or data in flash memory. It ran on two standard AAA batteries. It was able to retain enough energy for 10-15 minutes to prevent data loss during battery replacement. It had 2 megabytes of memory, large at the time, and used Palm OS 3. (Palm also produced an upgrade card for the Pilot series, which made them functionally equivalent to a Palm III.) Meanwhile, with Palm Computing now a subsidiary of 3Com, the founders felt they had insufficient control over the development of the Palm product.
As a result, they left 3Com and founded Handspring in June 1998. When they left Palm, Hawkins secured a license for the Palm OS for Handspring, and the company became the first Palm OS licensee. Handspring went on to produce the Handspring Visor, a clone of the Palm handhelds that included a hardware expansion slot (early Palm devices also had a hardware expansion slot, however this was for device upgrade purposes, not peripherals) and used slightly modified software. The next versions of Palm used Palm OS 3.1. These included Palm IIIx with 4 Megabytes of memory, Palm IIIe without flash memory or hardware expansion slot (and available for lower price), Palm V with 2 Megabytes of memory, and, Palm Vx with 8 Megabytes of memory. Palm VII had wireless connection to some Internet services, but this connection worked only within the United States. It used Palm OS 3.2.
Palm IIIc was the first Palm handheld with a color screen. It used Palm OS 3.5 which provided extensive tools for writing color applications. Some of these newer handhelds, for example Palm V, used internal rechargeable batteries. Later this feature became standard for all Palms. Palm handhelds up to 2002 contained Motorola DragonBall processors, part of the Motorola 68000 family. Starting with the Palm Tungsten, the platform transitioned to the ARM architecture with Texas Instruments, Samsung, and Intel as suppliers. As ARM had previously been used in the Apple Newton series, the platform had significant investment in mobile and low-power applications.
