Page 1Installation Instructions: AM-137 Board AM-1600/1400 Upgrade
1.0INTRODUCTION
These instructions explain how to install an Eagle 100 AM-137 board into an
AM-1600/1400 desktop or deskside computer. The AM-137 board replaces your current
CPU board with very little modification. In fact, with the exception of a rear panel
change, the AM-137 hardware installation is exactly the same as installing your current
CPU board. With the AM-137 board installed, you will be able to take advantage of
Alpha Micro’s Eagle/Roadrunner technology, which includes an MC68EC030 40MHz
processor and peripheral support for both SCSI-1 and SCSI-2 devices.
Besides a tremendous performance increase, the AM-137 also supports a larger
number of SCSI peripherals than your current CPU board. Your AM-1600/1400 CPU
board supports a maximum of four SCSI peripherals (SCSI IDs 0 through 3). The
AM-137 board will support up to seven SCSI peripherals (SCSI IDs 0 through 6).
The following information indicates the appropriate AM-137 board version for your
particular configuration:
Board Version Configuration
DWB-00137-00 Deskside, 8 serial I/O ports
DWB-00137-01 Desktop, 8 serial I/O ports
DWB-00137-02 Desktop, 4 serial I/O ports
DWB-00137-04 Deskside, 4 serial I/O ports
Super I/O is another important AM-137 board feature available to AMOS 2.2C users.
The AM-137 board’s on-board serial ports and any AM-318 board serial ports can take
advantage of a feature called Super I/O. Super I/O handles character output in a much
more efficient manner than any other previously released AMOS serial port driver. This
greatly reduces the load on the CPU and makes more CPU cycles available for other
tasks. AMOS 1.4C does not support Super I/O. See Appendix C for more details.
If your computer includes an AM-214 floppy controller, you will need to include an
AM-219 floppy controller with your AM-137 upgrade order. The AM-214 board is not
compatible the AM-137 board.
If your AM-137 upgrade order includes a new SCSI disk drive, it may include
(depending on how it was ordered) a factory loaded AM-137 compatible AMOS
operating system. If you receive a drive with factory loaded software, it will be clearly
labeled indicating the type of software loaded, the bitmap size, and the number of
logicals. Also, please read the information in Appendix D, which provides information on
configuring the SCSI dispatcher and explains how to transfer software from your old
drive to your new drive.
