The 78 pin connector may be terminated using any of the following terminal styles; Crimp, Solder, or Printed wiring board (PWB).
There are three general types defined in the specification; Standard density (size 20 contacts), High density (size 22D contacts), and Standard density (size 20 IDC contacts) in this connector family.
The 78-pin connector only uses size 22 contacts, in a number 5 shell size.
