Предлагам на вашето внимание Мобилен компютър - PDA баркод четец Intermec 2435 .

Галерия със снимки на този линк http://imgur.com/a/584ER[/url]

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.

Устройствата съм ги тествал до там , че boot-ват и лазера чете произволни баркодове без проблеми.


Сега и интересните части, който могат да се ползват вътре

-- 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
• Vadem Power Management Unit (PMU)
• Optionally combines with external VG-660 single-chip LCD VGA controller to drive
640x480 and lower resolution VGA compatible LCD panels.
