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 :
