Overview - PC/+Vs

PC/+Vs Single-board 4"x4" Computer
Product Information - NOT FOR NEW DESIGNS

Note: This product will eventually be replaced with the new PC/II+vxe.
The PC/+Vs is megatel 4x4Family V40-based single-board computer which boasts a complete IBM PC compatible CPU with on-board VGA video and disk controllers, all standard I/O functions and low power consumption.

By utilizing LCA and surface mount technology, Megatel's engineers have incorporated all of the most necessary elements for an IBM PC® compatible microcomputer, on a small 100 x 100 mm (4" x 4") PCB.

The PC/+Vs includes up to 2048 KB of ROM space, 640 KB User DRAM, SCSI Host Adapter, Floppy disk controller, VGA Video/LCD controller, and all standard Serial/Parallel I/O ports, combined with a 20 MHz V40 Cpu.
