AM-318 and AM-359 serial ports, as well as the Eagle 100’s eight on-board serial ports
and Eagle 550’s four on-board serial ports can take advantage of a feature called Super
I/O. Super I/O handles character output more efficiently than any other AMOS serial port
driver, reducing the load on the CPU and making more CPU cycles available for other
tasks. See Appendix C for more details.
Parallel I/O Capability
Eagle 100 computers have one standard-speed parallel port. Eagle 300-500 computers
have two high-speed parallel ports, and Eagle 550 computers have four high-speed
parallel ports. All Eagle parallel ports support the industry standard Centronics interface
and use 25-pin shielded connectors. See Appendix A for the 25-pin parallel connector
signal pinouts.
To insure the reliability and performance of your parallel ports, avoid using parallel
printer cables longer than six feet.
External SCSI Port
Your computer includes an external SCSI (Small Computer Standard Interface) port to
which you can attach additional SCSI compatible storage devices. Additional SCSI
devices can include hard disk drives, a CD-ROM drive, or magnetic tape storage
devices.
Add-on Equipment
The only thing you need to add is a terminal. It allows you to input and display the data
processed and stored by the components discussed above. You will probably want to
also add a printer to provide printed copies of your data. Your Value Added Reseller
(VAR) may have provided these items as part of your computer purchase.
If you want to expand your computer in the future by adding additional storage and
backup devices, see the
Eagle Computer Service Manual for a diagram of where
additional peripherals should be located in your cabinet.
Communications Options
Eagle 300-500 computers and Eagle 550 computers have two high performance
Ethernet ports accessible from the computer’s rear panel. One of the ports uses a
shielded 15-pin A.U.I. connector; the other port uses an RJ-45 10Base-T connector. The
15-pin A.U.I. connector can be converted to thin Ethernet operation with the addition of
a commercially available MAU transceiver. Ethernet is also available on Eagle 100
computers as an option, and requires the installation of Alpha Micro’s AM-366 Ethernet
board.
