ISA BUS PIN ASSIGNMENT

 

 

There are two edge connector (called 

“

gold fingers

“

) on this CPU Card, on the 

right hand is the connector of ISA Bus, followed up by PCI BUS connector. The 
ISA-bus connector is divided into two sets: one consists of 62 pins; the other 
consists of 36 pins.

 

The pin assignments   are as follows :
