Page 19Installation Instructions: Roadrunner 030 & 040 AM-1000 / AM-1200 Upgrade
The illustrations on the following pages use the AM-177 CPU board as an
example of how to install the AM-985 board. The procedure used for the AM-167
board is exactly the same; the only difference is that none of the screws holding
the metal frame around the AM-167 board need to be removed to install the
AM-985 board.
2.If you are upgrading an AM-1200 computer, you must remove some of the screws
holding the AM-177 board’s metal frame in place in order to install the AM-985
board. Use a #2 phillips-head screw driver to remove the screws as indicated in
the following figure. Once the screws have been removed, you will be able to lift
the frame high enough to allow you to install the AM-985 board.
3.Carefully remove your 68000 or 68010 CPU chip from its socket on the CPU
board. It is not necessary to remove the boot PROMs from the AM-167 or AM-177
board. If your CPU board has a 68000 or 68010 CPU chip that is soldered into
position, you must make arrangements to have the chip un-soldered. See the
section on mechanical compatibility (appearing earlier in this document) for more
information on un-soldering the CPU chip.
4.On the bottom of the AM-985 board, an addtional 64-pin socket has been
installed. This socket protects the pins on the bottom of the AM-985 board during
shipment and during installation.
5.In some computers, there may be two configuration jumpers (shorting blocks) that
stick up high enough above the AM-167 or AM-177 board as to interfere with the
installation of the AM-985 board. If you run into this problem, you will find two "low
profile" configuration jumpers in the product installation kit. Replace the two long
jumpers with the two low profile jumpers if necessary.
6.Using the following two figures as a reference, use one hand to carefully press the
AM-985 board into the 64-pin socket on the CPU board, while using the other
hand to support the opposite side of the AM-167 or AM-177 board. You want to
avoid flexing the main CPU board!
7.After the AM-985 board has been installed, you will need to re-install the screws
removed from the metal frame on the AM-177 board. A small rubber button on the
AM-985 board prevents the AM-985 board from coming into contact with the metal
frame. Make sure the rubber button is properly in place between the AM-985
board and the metal frame before you tighten the metal frame screws.
