FULLY PLUG COMPATIBLE with Encore

The FES-1 replaces dual 8" floppy drives and dual 5¼" floppy drives used as boot devices on Gould/SEL and Encore computer systems. It is available with 3½", 5¼", or a combination, in three different models. The FES-1 uses currently available ANSI standard floppy disk drives and media for improved reliability and maintainability.

FES-1 is fully plug compatible with the Gould/SEL Line Printer/Floppy Disk (LP/FD) controller, and is easy to install. It is housed in a universal chassis for rack mount or table top use. Rack mounting ears are provided with the unit for mounting in standard 19" racks and cabinets.

Auto-Standby

The FES-1 has circuitry that spins down the floppy drive motors after 2.5 minutes of inactivity, until the next read, write, or seek action. This Auto-standby feature greatly extends the floppy head and media life. The FES-1 can be configured for continuous operation with an internal jumper.

UNIT ID SELECT

An internal jumper allows either floppy drive to be set as the default Unit 0 for boot purposes. The drive ID can be reversed with jumpers inside the FES-1.

SOFTWARE COMPATIBLE

Encore currently distributes machine language for older computer cold start, operating system, and diagnostic software on 5¼" or 3½" media, that is compatible with the FES-1. An operating system utility allows for formatting of new media and copying of existing media to new. This utility can target either floppy drive Unit 0 or Unit 1. The FES-1 is fully compatible with the operating system disk utilities.
