Page 13: Remote Reset Capability
You can also enable remote reset by using the remote reset cable, DWB-10323-00, available from Alpha Microsystems. This works even if port 0 is on an AM-314 or AM-318-10 board, which do not support remote reset through port 0, as described above. See PDI-10323-00, Remote Reset Adapter, for details. - Page 14 Eagle Series Computer Service Manual Page 11 AM-319(-20) Battery Replacement The AM-319(-20) board uses two three-volt lithium batteries (part #BR1225). The batteries are slightly smaller than a dime, and are secured side-by-side in a plastic holder. When the batteries need replacement, you must replace both batteries at the same time.

Page 22: Peripheral Mounting
There are two basic types of Eagle system rear panels: the Eagle 100-500 rear panel, and the Eagle 550 rear panel. The two types of rear panels require a different method of unfastening the main electronics board. - Page 23 Page 20 Eagle Series Computer Service Manual These two half-height 5.25" mounting positions support hard disk drives. Peripherals mounted in either of these locations cannot be accessed via the computer's front panel. These four half-height 5.25" mounting positions are designed for peripherals that use removeable media, like diskette and tape drives.
