9.0INSTALLING THE AM-986 BOARD
With the AC power cord unplugged and the top cover removed, the components inside
your computer are vulnerable to damage caused by static discharge. Your body and
clothing are capable of storing an electrical charge that can damage or destroy
unprotected electronic components. Prior to handling any computer hardware, make
sure your work area is properly protected against static discharge. There are a number
of commercially available static protection devices designed specifically to protect your
equipment from harmful static discharge.
If you did not order a SCSI disk drive that was pre-loaded with a Roadrunner compatible
AMOS operating system, you need to update the software on your existing drive. The
software download and configuration procedure, located in Appendix C, must be
completed before the Roadrunner hardware is installed in your computer.
Before you install the AM-986 board, you must first complete the steps outlined below:
1.Follow the instructions in your computer owner’s manual that describe how to
open the AM-2000M pedestal chassis to gain access to the AM-145 board.
2.If you are currently using the AM-121 VPC board, it must be removed in order to
install the AM-986 board.
3.The 68020 CPU chip must be removed from its socket located at U127 on the
AM-145 board. The CPU chip is shown in the AM-145 illustration. To remove the
CPU, gently pry the chip loose using a small flat blade screw driver. Work around
the chip lifting from corner to corner and side to side until the chip 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.
4.Remove the 6-32 phillips-head screw as indicated in the illustration.
5.Do not remove the AM-145 board’s boot PROMs.
6.The memory boards plugged into your AM-145 board are not supported for use
with Roadrunner hardware. Remove the bracket holding the memory boards in
place. Remove any memory boards plugged into the AM-145 board at locations
J5, J6, J7, and J8. Also, if you are using an AM-522 intelligent controller, it must
also be removed. Along with the AM-522 board, you should also remove the
AM-528 board and your ESDI drive (or drives).
7.The illustration shows a special bracket (DWF-20538-00) designed to tie the
AM-986 and AM-145 boards together. Install the bracket on the AM-986 board as
shown indicated.
8.The illustration indicates the location of a standoff designed to hold the AM-986
board. Most AM-145 boards will have a nylon standoff installed at this location.
