The ElectricRay is a high performance PCI/ISA Single Board Computer designed to support single Intel CeleronTM or dual Pentium® III processors operating up to 850MHz. The ElectricRay supports up to 768Mbytes ofSDRAM and up to 64MB ATA-Disk Chip for program and data storage. Additional features include AGP Video,dual 10/100 Base-TX Ethernet, and PMC expansion. The ElectricRay supports a full set of standard peripheralssuch as IDE, floppy, RS-232 serial ports, parallel port, USB, keyboard and mouse. Other industrial features are;serial port console redirection, battery backed real-time clock, CPU temperature monitors, and watchdog timer.

The ElectricRay front plate connectors include AGP Video, Dual Ethernet, PS/2 Keyboard/Mouse, and USB.PMC expansion is accomplished with an adapter board that elevates the PMC front plate to the next slot. Thehigh performance of the ElectricRay makes it the ideal solution for applications which require Dual Pentium® IIIprocessors in a rugged PCI/ISA form factor.
