Die Pinbelegung der wichtigsten SCSI Stecker:
Hier sehen sie die Gegenüberstellung der wichtigsten
SCSI-Steckverbinder. Es ist nur auch relativ leicht sich den einen
oder anderen Adapter selber zu löten.

Alle GND-Anschlüsse liegen gemeinsam auf der entsprechenden
Signalmasse des Hostadaptor/Computer. Bei IDE Pin 39, ist das Signal
für eine Zugriffs-LED herrausgeführt. Es wird hier der
generelle IDE-Zugriff angezeigt.
Pinbelegung der üblichen (E)IDE-Buchse, auch 2.5":
Hier finden Sie nochmal den IDE-Bus als 3.5" und 2.5"
Gegenüberstellung wie es in der c't 5/92 S.198 dargestellt wurde.
Die Bussignale sind bis auf die +5 Versorgungspannung bei 2.5" im
2mm Raster gleich.
