10.0INSTALLING THE AM-985 BOARD
Prior to handling any computer hardware, GROUND YOURSELF. The best ground is
the chassis cabinet that houses the boards. Touch the cabinet prior to picking up,
installing, or removing any board. Do not unplug the AC power cord from the cabinet,
but make sure the power switch is turned OFF. Unplugging the computer cabinet
isolates it from the common earth ground, leaving it vulnerable to static discharge.
If you did not include a new SCSI disk drive with your Roadrunner upgrade, you need to
load a new Roadrunner compatible AMOS operating system 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.
The AM-985 board plugs into the 64-pin socket used by the 68000 or 68010 CPU chip
in your AM-167 or AM-177 board. Use the following instruction for installing the AM-985:
1.Remove all the screws holding the computer’s top cover in place. Once the
screws have been removed, set the top cover out of the way.
