AM-966-10 CONNECTIONS

The Eagle 250 uses the AM-966-10 front panel display board, which connects to the AM-138. In most
cases, you should not need to connect any wires to or disconnect any wires from the AM-966. However,
if any of your front panel display lights stop working, or if one or more wires come loose from the AM-
966, you can refer to the picture and list below to check and, if necessary, remake any connections.

WARNING!
The SSD chip and boot
PROM on the AM-138
board require a
specialized tool for
their removal. If you
attempt to remove
the SSD chip or
boot PROM using
a screwdriver or
pocketknife, you
could easily damage
both the chip and the
socket. This type of chip
extraction tool is available
at retail stores specializing
in electronic components.
