Description

486 PC/AT VMEbus CPU with Dual-Port Memory, PC/104, and Cache Simple Type: CPU Board The VMIVME-7487 single-board microcomputer is a complete IBM PC/AT 80486 compatible microcomputer with the additional benefits of Eurocard construction and full compatibility with the VMEbus Specification Rev. C.1. The VMIVME-7487 has an advanced VMEbus interface, mailbox registers, and RAM that is dual-ported to the VMEbus, making it ideal for multiprocessor applications. VMIC’s VMIVME-7487 has two operating modes: a standard PC/AT compatible mode, and a VMEbus controller mode. Upon powerup it functions as a standard PC/AT. It executes a PC/AT-type power-on self-test, then boots up MS-DOS, Windows, OS/2, NextStep, XENIX, or any other PC/AT compatible operating system. After booting, the VMIVME-7487 may take on the additional functions of a VMEbus controller and interact with other VMEbus modules. The VMIVME-7487 may also be accessed as a VMEbus slave board.
