Overview
  • All-in-one single board 486 computer with an on-board VGA CRT/flat-panel controller.
  • Packs all the functions of an industrial computer, and display capabilities, on a half-size card.
  • Fully PC/AT compatible, so your software will run without modifications.
  • On-board VGA CRT/flat-panel controller uses the C & T 65550 chipset, and supports resolutions up to 1024 x 768 in 64K colors.
  • On-board features include:

    2 high-speed serial ports (RS232) with 16C550 UARTs
    one bi-directional parallel port
    IDE hard-drive controller
    and floppy drive controller.

  • The watchdog timer will automatically reset the CPU or generate an interrupt for any system halt situation.
  • Provides two 72-pin SIMM (Single Inline Memory Module) sockets for on-board DRAM. This gives you the flexibility to configure your system memory to 128MB using the most economical combination of SIMMs.
  • Power management to minimize power consumption.
  • CMOS components and complies with the 'Green Function' standard.
  • For additional functions, add any industry standard PC-104 expansion module.
Lely Tempustech, LLC. provides numerous PC-104
modules to meet your system requirements
