REMOVING THE AM-319 BOARD
1. Label all cables between the AM-319 and the rear panel, then unplug them from both the rear
panel and the AM-319.
2. Remove the two male-female standoffs attaching the AM-319 to the back panel.
3. Unplug all cables still attached to the AM-319 (the X-bus cables, power cables, SCSI cable, and
front panel display cable). Label the power and display cables, as they’ll be used in the Eagle
250. If you will be using the Wide SCSI-2 bus on the AM-138-10, disconnect the narrow SCSI
cable from all devices and the external connector and remove the cable.
4. Remove the two screws attaching the AM-319’s mounting plate to the chassis, as shown in
Figure 7-5.
