Предлагам на вашето внимание
Мобилен компютър - PDA баркод четец Intermec 2435 . Устройствата принципно работят, но не съм изобщо наясно със складов и магазинен хардуер, така че ги представям интересни относно частите, които ще опиша, и мисля че представляват интерес за хората във форума. Някой ако разбира от този вид хардуер може да ги препродаде по предназачение. Гледам че подобни у-ва вървят втора у-ба за доста високи три цифрени суми. (

Главен процесор: Vadem VG230 Japan . Гледам че с него и подобни има интересно проекти из нета, като Arcade емулатори например. Накратко:
GENERAL DESCRIPTION
The Vadem VG230 is a one-chip PC platform which provides a highly battery-efficient basis for
OEMs to develop cost sensitive, DOS-based personal electronic products. The chip contains all
standard XT peripherals, additional high-value peripherals and an ISA bus. For long battery life,
the VG230 offers extensive and proven power management capability. In addition to a +5V
version, a version is offered which operates at +3V.
The VG230 contains the 8086-compatible 16 MHz NEC V30HL processor. It also embodies a
standard XT architecture combined with hardware and software features facilitating the rapid
design of products with extensive ROM-based software. PC Card mass storage and miniature
peripherals (I/O cards) following the PCMCIA 2.1 (JEIDA 4.1) standard are supported. The
VG230 is packaged in a single 160-pin CMOS chip and handles all PC functions including 16-
bit CPU, XT core logic,
LCD controller, keyboard scanner and PC Card controller. All that is
required for a basic system is the VG230, memory, power supply, display and associated
packaging.
PRODUCT OVERVIEW
• Single-chip permits glueless implementation of a fully compatible PC-XT.
•
Standard-design 16-bit, 16 MHz NEC V30HL processor core integrated on-chip.• Complete hardware and firmware support for memory-saving “execute-in-place” ROM
applications.
• Field-proven, industry standard power management based on activity monitoring lengthens
battery life.
• Scans up to 101 keys without an external keyboard controller.
•
Integrated CGA LCD controller and 640x400 AT&T standard controller. Supports a wide
variety of panel resolutions from below CGA to 400-line displays.
• LCD controller supports hardware “ink plane” for pen-based applications.
• Dual PCMCIA 2.1 (JEIDA 4.1) PC Card slot support allowing “hot” insertion/removal (with
external buffers).
•
Integrated serial port, real-time clock, programmable interrupt controller, DMA controller
and internal timer.• Deactivating keyboard scan enables a second PCMCIA card slot, a bi-directional parallel.
port and a standard XT keyboard interface.
• Support for DRAM, SRAM and PSRAM memory.
• Supports up to eight 8-bit RAM banks and up to six 16-bit RAM banks.
• ICE support simplifies debugging of system designs.
• 8250 compatible UART.
• XT keyboard interface.
GENERAL DESCRIPTION VADEM VG230
2
• EMS 4.0 compatible memory subsystem, supports up to 64Mbytes.
• Real Time Clock with CMOS RAM

LCD CGA 160 x 128 дисплей с подсветка. Размери на видимата площ 62мм X 53mm. На него се виждат следните чипове: 73101YXA и C324G. На следния линк някой е подкарал подобен, но нашия случай процесора има вграден CGA контролер, така че нещата може да стоят и по малко по друг начин.
http://www.pcbheaven.com/exppages/Reverse-Engineering_an_LCD_Display/?p=0Пакета от батерии се състои от два броя стандартни Lion клетки.
Към терминалите вървят и външни зарядни за по 4 броя допълнителни батерии. При покупка на 5 броя давам едно зарядно безплатно.
Някой от у-вата имат и дръжки със спусък.
Цена за 1 брой
