AM-990 SBC Computer Service Manual
If you are going to mix 4MB and 16MB memory boards in your SBC, make sure you
install the 16MB boards first followed by the 4MB memory boards.

SBC Expansion I/O

There are two 60-pin connectors on the SBC CPU board, each capable of supporting 32
serial ports. The first 32 ports are controlled by connector J7 and the second 32 ports
are controlled by connector J8.
Connector J7 supports the standard interface drivers for all of Alpha Micro's paddle card
devices designed for the AM-355 I/O bus. AM-355 I/O boards attached to connector J7
use the same interface driver used by the two serial ports on the CPU board,
AM140.IDV. AM-358 and AM-359 I/O paddle cards, and any other AM-355 I/O bus
paddle cards attached to the J7 connector will use the drivers designed for those
specific devices. For example: AM358.IDVand AM359.IDV.
The J8 connector ONLY supports AM-355, AM-358, and AM-359 I/O paddle cards.
AM-355, AM-358 and AM-359 I/O paddle cards attached to connector J8 use special
interface drivers: AM355B.IDV, AM358B.IDV and AM359B.IDV.
For information on jumper settings, port numbering, and I/O addresses, see the
installation guide shipped with the AM-355 I/O bus device you are installing.
