PC/104 Plus Processor Board

The PC/104 Plus Single Board Computer Module is a rugged, fanless x86-based single board computer in the PC/104 Plus formfactor. It is a high reliability design built around the ZFx86 processor and uses a Polyimide PCB to provide temperature, shock and vibration resilience.

The ZFx86 processor provides support for industry standard architecture and peripherals, ensuring compatibility with a wide range of operating systems, such as VxWorks, Windows 9x/NT, Linux, QNX, MSDOS and DRDOS. The CPU speed can be 33 MHz, 66 MHz or 100 MHz over the full extended temperature range of -40 C to +85 C, or 128 MHz over the temperature range -20 C to +70 C.

The 100% PC-compatible Phoenix embedded PC BIOS is stored in 2 Mbyte reprogrammable Flash EPROM, leaving space for a complete Linux and VxWorks kernel image along with the boot loaders for both, enabling a dual-boot Linux / VxWorks system.

A total of 128 Mbytes of SDRAM is soldered to the board for increased resistance to shock and vibration. For cost sensitive applications, 32 or 64 Mbyte options are available.
