E.9 IDE CONNECTOR
The IDE drive is connected through J100, a straight 2mm pitch 44-way connector. Pin
assignments follow.
Pin 1 of the J100 connector can be identified by looking at the silk-screen legend on
the TP400 PCB. A ’1’ symbol is placed close to pin 1. All odd numbered pins are in
one row and all even numbered pins are in the other row.
