3.2.3Installing the AM-987 on the AM-140 CPU Board
After performing the required rework on the AM-140 CPU board, the board will have to
be re-installed in the system chassis.
However
, it may be advantageous to do some
of the next installation steps while the CPU board is still out of the chassis. Items
such as removing the CPU chip (or AM-540 board), and the AM-121 VPC board (if
applicable) may be more accessable while working on a flat bench! So take a moment
to scan down through the next few steps and decide for yourself before re-installing the
AM-140 CPU board.
To install the AM-987 board refer to the next illustration and complete the following
steps:
1.The memory boards plugged into your AM-140 board are not supported for
use with Roadrunner hardware. Remove any memory boards plugged into
the AM-140 board at locations J12, J13, J14, and J15.
2.The 68030 CPU chip (or the AM-540 board) must be removed from its
socket located at U144 on the AM-140 board. The CPU chip location is
shown in the AM-140 Preparation Illustration. To remove the chip or
AM-540 board, gently pry the chip or board loose from the socket using a
small flat blade screwdriver. Work around the edge lifting from corner to
corner and side to side until it pops loose from the socket. Don’t rush this
operation! If too much force is used you could break some of the pins or
the ceramic case on the CPU chip.
3.If you are currently using the AM-121 VPC board, it must be removed in
order to install the AM-987 board.
4.Leave out the (4) 6-32 phillips-head CPU mounting screws as indicated in
the illustration.
5.Do NOT remove the AM-140 board’s boot PROMs.
