1.9.3Boot PROM Removal and Installation
If it becomes necessary to update the boot PROM on the AM-174 Roadrunner board,
the type of socket used for the boot PROM requires a special IC removal tool. See the
illustration below for more information:
The boot PROM IC used on
Roadrunner boards requires
a specialized tool for its
removal. If you attempt to
remove the boot PROM
using a screwdriver or
pocketknife, you could
easily damage both
the chip and the
socket. Use a chip
extraction tool like this,
which is available at retail
stores that specialize in
electronic components.

1.10AM-987 JUMPER CONFIGURATION
The AM-987 board, which attaches to the system CPU board, has only two jumpers.
Refer to the following illustration for the physical locations of these jumpers.
Jumper JP1 is provided to enable termination power to the X-BUS cables. This jumper
is factory installed and should not be removed!
Jumper W1 provides the ability to select between the two CPU header connectors at
locations U14 and U14A. The two CPU headers are functionally identical but allow the
AM-987 board to be physically oriented to fit on and within several different CPU/system
configurations. It’s easy to visually confirm which header is enabled by observing the
position of the installed jumper. When W1 is installed toward the header at U14, then
U14 is enabled. And, conversely, when W1 is installed toward the small arrow pointing
to U14A, then U14A is enabled.
The CPU header connector at U14 will be used when upgrading the AM-140
(AM-3000M), AM-185-50 (AM-3000 VME), and AM-137 (Eagle 100) CPU’s. The header
connector at U14A will only be used when upgrading the older AM-185-00 CPU.
