" The IBM Realtime Interface Co-processor Multiport/2
or X.25 Interface Co-processor/2 supports up to 16 different
adapters in various RAM/ROM locations, utilizing 7 different
interrupt levels and various clocking options.
The Physical Card Designation will be automatically
configured with the following rules:
1. I/O address (Physical Card Designation) is the
lowest possible interrupt level.
The I/O address defines the physical card designation of the
IBM Realtime Interface Co-processor Multiport/2 or X.25 Interface
Co-processor/2. This is actually a RANGE of addresses, 8 bytes wide.
The preferred address range is the lowest available. "

"The IBM Realtime Interface Co-processor Multiport/2 or X.25 /2

configured with the following rules:
1. Memory address is the lowest possible and the Shared
Storage Window size is 8KB.
The Shared Storage Window is an unused ROM or RAM address range
that is used as a window into the RAM on the IBM Realtime
Interface Co-processor Multiport/2 or X.25 /2. The preferred
choice is the window at the lowest address with a size of 8K.
The 8K window size is compatible with the IBM Realtime Interface

"The IBM Realtime Interface Co-processor Multiport/2 or X.25 /2
supports up to 16 different adapters in various RAM/ROM locations,
utilizing 7 different interrupt levels and various clocking options.
The Interrupt Level will be automatically configured with the
following rules:
1. Interrupt Level 7 is requested.
2. Interrupt Levels are then requested for subsequent cards
in ascending order.
The interrupt level is the prioritized interrupt request
line on which the IBM Realtime Interface Co-processor
Multiport 2 or X.25 /2 will interrupt the Personal System 2.
The interrupt priorities are as follows (greatest priority
first): 9, 10, 11, 12, 3, 4, 7.
The preferred interrupt level is 7. "
