Develop of Psion

For many years the computer industry has brought out faster, smaller, more powerful and efficient computer components. The netbook was born from the One Laptop Per Child (OLPC) project IT for education needed. At around the same time Asus brought out a competing laptop called the EEPC. The name netbook however came from a device that Psion developed, the name has been used for all devices that resemble small Internet capable devices ever since. Netbook is a very small notebook computer that usually has between an 8 to 11 inch screen, has no DVD/CD drive and all other components are chosen to keep power consumption at its lowest. This means that the netbook you have or may want to get will not have as much power as a notebook and no way as near a desktop. But on the other hand you will not need all that power anyway. Choose the right netbook for you activity, Psion is one of netbook you can choose. There many kind of Psion like Psion revo, psion 5 mx and so many more.

The Psion netBook is a small subnotebook type computer developed by Psion (now Psion Teklogix). Similar in design to the later, consumer-oriented Psion Series 7, it has a clamshell design, a VGA-resolution touch-sensitive colour screen, 32 MB RAM, 190 MHz StrongARM SA-1100 processor and a QWERTY keyboard. The RAM is upgradeable through the addition of an extra 32 MB chip. The netBook is powered by a removable Lithium Ion rechargeable battery, giving a battery life of between eight and ten hours. The netBook runs the EPOC ER5 operating system (the predecessor of SymbianOS), operating system runs from RAM. A Java run time environment, conforming to Java version 1.1.8, is available. Now we will give you some resume about psion variant.

Ø  Psion 5 mx

The Psion 5 mx is a PDA from Psion. It comes in two main variants, the Series 5 (launched in 1997) and the Psion 5mx (1999), the latter having a faster processor, clearer screen, and updated software. There is also a rare Psion 5mx Pro, which differs only in having the operating system loaded into RAM and hence upgradeable. The external appearance of the Psion Series 5 and the Psion Series 5mx are broadly similar, but their mainboards and other internal components are different and not interchangeable. The screens are not interchangeable because of different screen cables. At the heart is a 32-bit RISC-based ARM710T processor with MMU running at 18 MHz (Series 5) or 36 MHz (5mx), with 4, 8 or 16MB of RAM. It's powered by two AA batteries, typically giving 10 – 20 hours of use. The display is a touch-sensitive, backlit half-VGA (640 x 240 pixel) LCD with 16 greyscales. The keyboard is generally considered to be among the best for its size, with large-travel keys and touch-type capability. Both RS-232 and IrDA (infra-red) serial connections are provided, along with a speaker and microphone, giving dictation ability as well as playing music. External storage is on CompactFlash.

Ø  Psion ReVo

The Psion Revo, launched in 1999. It is the light version of Psion 5mx. It is software-compatible with the 5mx and has the same processor but is more lightweight (200g vs 354g of 5mx), and smaller (157x79x17mm). In comparison with the Series 5/5mx, the Revo has a smaller screen (480x160 vs 640x240 of Series 5/5mx) and also lacks a flash-card slot and a backlight. The Psion Revo comes in two main variants, Psion Revo and Psion Revo Plus having 8 and 16MB of RAM respectively. It is powered by a 36 MHz ARM 710T microprocessor. The hardware is equipped with irDA wireless infrared communication system and a touchscreen, small suite of office and communications programs built into the ROM chips. Psion produced two versions of the Revo for the Chinese market called the 618C (Traditional Chinese) and 618S (Simplified Chinese). An open source project OpenPsion, formerly PsiLinux, aims to port Linux to the Psion Revo and other Psion PDAs. See the OpenPsion site or the site of Revol, which is an optimized version of OpenPsion for the Revo.

In October 2003 Psion Teklogix announced the netbook pro, replacing the original netBook, upgraded with a 16-bit colour SVGA (800 × 600 pixel) display, 128 MB of RAM, and a 400 MHz Intel XScale PXA255 processor running Windows CE .NET 4.2 instead of EPOC. An open source project OpenPsion, formerly PsiLinux, aims to port Linux to the Psion netBook and other Psion PDAs.
