Xcopilot
Xcopilot is a Palm Pilot emulator that runs under Unix/X11. It offers emulation of the timer, serial ports, touch pad and LCD along with Motorola 68000 emulation (m68k), specifically the Freescale DragonBall used in Palm Pilots until they switched to Intel XScale ARM processors (later DragonBalls were based on an ARM core not a 68000 but retained the same name, however were not used by Palm.) Xcopilot was originally developed by Ivan Curtis with contributions from Ian Goldberg, Jef Dionne, Kresten Krab Thorup, and Andrew Pfiffer based on the Windows program Copilot. While the original Copilot application eventually turned into the Palm OS Emulator, the Unix/X11 port branched off and enjoyed its own popularity. Written in 1997, Xcopilot was aimed at developers of applications on the Palm OS Palm OS (also known as Garnet OS) was a mobile operating system initially developed by Palm, Inc., for personal digital assistants (PDAs) in 1996. Palm OS was designed for ease of use with a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palm OS Emulator
Descended from Copilot, Palm OS Emulator is used for writing, testing, and debugging Palm OS applications. Palm OS Emulator emulates Motorola 68000-class devices and has intimate knowledge of Palm OS's inner working, allowing for the close monitoring of correct application operation. Unlike Xcopilot (another descendant of Copilot), Palm OS Emulator will not boot uClinux. By using "skin" files, Palm OS Emulator could very closely mimic the appearance of many models of Palm handheld. All versions of Palm OS Emulator require a file containing the ROM image to boot. ROM image files can be obtained from PalmSource (now part of Access Co., Ltd), or downloaded from a real Palm device. Palm OS Emulator supported Palm models produced by Palm, Handera, Handspring, and Symbol. Palm OS handhelds produced by Sony (the Clie line) were supported by a separate, Sony-specific fork of Palm OS Emulator. Both Copilot and Palm OS Emulator are released under the GPL v2. Versions were developed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palm Pilot
The PalmPilot Personal and PalmPilot Professional are the second generation of Palm PDA devices produced by Palm Inc (then a subsidiary of U.S. Robotics, later 3Com). These devices were launched on March 10, 1997. Accessories and pricing Palm also sold the 10201U modem at 14.4 kbit/s, introduced at a price of $129 (this modem is also compatible with the Palm III and Palm IIIx devices). An upgrade kit was also available, which allowed users of the earlier Pilot 1000/5000 devices to upgrade the OS, ROM, and RAM to match the PalmPilot Professional. Initially suggested retail prices upon launch were $399 for the PalmPilot Professional (1MB), $299 for the PalmPilot Personal (512KB), and $199 for the Upgrade Kit. Upgrade kits were also available to existing registered Pilot users for $99 for a limited time after the launch. These kits included IR capability, a new plastic memory door to accommodate the IR diodes, a memory card with 1 MB, the new ROM for Palm OS 2.0, and a CD- ...

Unix
Unix (; trademarked as UNIX) is a family of multitasking, multiuser computer operating systems that derive from the original AT&T Unix, whose development started in 1969 at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others. Initially intended for use inside the Bell System, AT&T licensed Unix to outside parties in the late 1970s, leading to a variety of both academic and commercial Unix variants from vendors including University of California, Berkeley ( BSD), Microsoft (Xenix), Sun Microsystems ( SunOS/ Solaris), HP/ HPE ( HP-UX), and IBM (AIX). In the early 1990s, AT&T sold its rights in Unix to Novell, which then sold the UNIX trademark to The Open Group, an industry consortium founded in 1996. The Open Group allows the use of the mark for certified operating systems that comply with the Single UNIX Specification (SUS). Unix systems are characterized by a modular design that is sometimes called the "Unix philosophy". According to th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
X Window System
The X Window System (X11, or simply X) is a windowing system for bitmap displays, common on Unix-like operating systems. X provides the basic framework for a GUI environment: drawing and moving windows on the display device and interacting with a mouse and keyboard. X does not mandate the user interfacethis is handled by individual programs. As such, the visual styling of X-based environments varies greatly; different programs may present radically different interfaces. X originated as part of Project Athena at Massachusetts Institute of Technology (MIT) in 1984. The X protocol has been at version 11 (hence "X11") since September 1987. The X.Org Foundation leads the X project, with the current reference implementation, X.Org Server, available as free and open-source software under the MIT License and similar permissive licenses. Purpose and abilities X is an architecture-independent system for remote graphical user interfaces and input device capabilities. Each person usi ...

Serial Port
In computing, a serial port is a serial communication interface through which information transfers in or out sequentially one bit at a time. This is in contrast to a parallel port, which communicates multiple bits simultaneously in parallel. Throughout most of the history of personal computers, data has been transferred through serial ports to devices such as modems, terminals, various peripherals, and directly between computers. While interfaces such as Ethernet, FireWire, and USB also send data as a serial stream, the term ''serial port'' usually denotes hardware compliant with RS-232 or a related standard, such as RS-485 or RS-422. Modern consumer personal computers (PCs) have largely replaced serial ports with higher-speed standards, primarily USB. However, serial ports are still frequently used in applications demanding simple, low-speed interfaces, such as industrial automation systems, scientific instruments, point of sale systems and some industrial and consumer ...

Motorola 68000
The Motorola 68000 (sometimes shortened to Motorola 68k or m68k and usually pronounced "sixty-eight-thousand") is a 16/32-bit complex instruction set computer (CISC) microprocessor, introduced in 1979 by Motorola Semiconductor Products Sector. The design implements a 32-bit instruction set, with 32-bit registers and a 16-bit internal data bus. The address bus is 24 bits and does not use memory segmentation, which made it easier to program for. Internally, it uses a 16-bit data arithmetic logic unit (ALU) and two more 16-bit ALUs used mostly for addresses, and has a 16-bit external data bus. For this reason, Motorola termed it a 16/32-bit processor. As one of the first widely available processors with a 32-bit instruction set, and running at relatively high speeds for the era, the 68k was a popular design through the 1980s. It was widely used in a new generation of personal computers with graphical user interfaces, including the Macintosh 128K, Amiga, Atari ST, and X6800 ...

Freescale DragonBall
Motorola/Freescale Semiconductor's DragonBall, or MC68328, is a microcontroller design based on the famous 68000 core, but implemented as an all-in-one low-power system for handheld computer use. It is supported by μClinux. It was designed by Motorola in Hong Kong and released in 1995. The DragonBall's major design win was in numerous devices running the Palm OS platform. However, from Palm OS 5 onwards their use was superseded by ARM-based processors from Texas Instruments and Intel. The processor is capable of speeds of up to 16.58 MHz and can run up to 2.7 MIPS ( million instructions per second), for the base 68328 and DragonBall EZ (MC68EZ328) model. It was extended to 33 MHz, 5.4 MIPS for the DragonBall VZ (MC68VZ328) model, and 66 MHz, 10.8 MIPS for the DragonBall Super VZ (MC68SZ328). It is a 32-bit processor with 32-bit internal and external address bus (24-bit external address bus for EZ and VZ variants) and 32-bit data bus. It has many built-in fu ...

Intel XScale
XScale is a microarchitecture for central processing units initially designed by Intel implementing the ARM architecture (version 5) instruction set. XScale comprises several distinct families: IXP, IXC, IOP, PXA and CE (see more below), with some later models designed as system-on-a-chip (SoC). Intel sold the PXA family to Marvell Technology Group in June 2006. Marvell then extended the brand to include processors with other microarchitectures, like ARM's Cortex. The XScale architecture is based on the ARMv5TE ISA without the floating-point instructions. XScale uses a seven-stage integer and an eight-stage memory super- pipelined microarchitecture. It is the successor to the Intel StrongARM line of microprocessors and microcontrollers, which Intel acquired from DEC's Digital Semiconductor division as part of a settlement of a lawsuit between the two companies. Intel used the StrongARM to replace its ailing line of outdated RISC processors, the i860 and i960. All the generatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microsoft Windows
Windows is a group of several proprietary graphical operating system families developed and marketed by Microsoft. Each family caters to a certain sector of the computing industry. For example, Windows NT for consumers, Windows Server for servers, and Windows IoT for embedded systems. Defunct Windows families include Windows 9x, Windows Mobile, and Windows Phone. The first version of Windows was released on November 20, 1985, as a graphical operating system shell for MS-DOS in response to the growing interest in graphical user interfaces (GUIs). Windows is the most popular desktop operating system in the world, with 75% market share , according to StatCounter. However, Windows is not the most used operating system when including both mobile and desktop OSes, due to Android's massive growth. , the most recent version of Windows is Windows 11 for consumer PCs and tablets, Windows 11 Enterprise for corporations, and Windows Server 2022 for servers.

Palm OS
Palm OS (also known as Garnet OS) was a mobile operating system initially developed by Palm, Inc., for personal digital assistants (PDAs) in 1996. Palm OS was designed for ease of use with a touchscreen-based graphical user interface. It is provided with a suite of basic applications for personal information management. Later versions of the OS have been extended to support smartphones. Several other licensees have manufactured devices powered by Palm OS. Following Palm's purchase of the Palm trademark, the currently licensed version from ACCESS was renamed ''Garnet OS''. In 2007, ACCESS introduced the successor to Garnet OS, called Access Linux Platform; additionally, in 2009, the main licensee of Palm OS, Palm, Inc., switched from Palm OS to webOS for their forthcoming devices. Creator and ownership Palm OS was originally developed under the direction of Jeff Hawkins at Palm Computing, Inc. Palm was later acquired by U.S. Robotics Corp., which in turn was later bought by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
