Chapter 1 – Introduction
The XVME-977 Hard Disk/Floppy Disk Module provides an easy way to integrate both
hard and floppy disk drives into a VMEbus system. Constructed for the industrial mar-
ket, where high levels of shock and vibration are the norm, the module is a single-slot
VME form factor disk drive with a 3.5-inch floppy drive and a 2.5-inch hard drive.
Compact and easy to install, the XVME-977 Hard Disk/Floppy Disk Module is an ideal
mass storage solution for a variety of VMEbus systems. This module is built to commu-
nicate with Xycom’s XVME-65x VMEbus PC/AT processors.
Power for the XVME-977 is provided by the P1 and P2 connectors. Signals are routed
through P2. Figure 1-1 illustrates this in a block diagram of the XVME-977.
