Overview - PC/+Vsc

PC/+Vsc 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/+Vsc is a Megatel 4x4Family single-board computer which boasts a complete IBM PC compatible V40 CPU with on-board VGA video/panel and disk controllers, all standard I/O functions and low power consumption on a rugged and cost-effective board.

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