PC/104-Plus single board computer
ZF Micro ZFx86, max. 100 MHz, 64 MB | APEX ZF Blue Chip Technology

The Apex ZF is a versatile, reliable X86 PC104+ board, offering a viable alternative for 186, 386 and 486 boards being phased out of production by AMD, Intel and STMicroelectronics. Available in 33MHz, 66MHz or 100Mhz processor options, the APEX ZF was conceived expressly for embedded applications, designed from the ground up with the most comprehensive set of x86 PC functionality.
The board's low power consumption eliminates the need for a fan and heat sink, combining a neat 96mm x 90mm footprint with a low physical profile. A typical 2 Watt power profile means the board can easily operate from batteries during a power failure or in remote locations draw power from a solar cell array. Extended temperature options are available for harsh environments.
Storage options include one ATA-4 compatible IDE channel supporting up to 2 devices and a CompactFlash socket, located on the board underside. Soldered directly to the PCB, the SDRAM is more mechanically robust than a SIMM or DIMM and will withstand the physical abuse found in industrial environments. An EEPROM device provides onboard non volatile storage. Comprehensive IO is provided by two USB 1.1 ports, two serial ports, a bi-directional parallel port and a 10/100baseT ethernet port. Eight 5V, 10mA, TTL GPIO lines support onboard data acquisition functionality. Mini PCI expansion supports a graphical interface and more special function I/O options such as wireless or dual LAN.
