Figure 4-9 The PDS card
PDS Card Shell 4
The PDS card is installed in a plastic shell that resembles a battery and fits into the
battery well on the left side of the case. The plastic shell is made up of several compo-
nents, including two clamshell halves, a bezel or cover, and an internal latch and spring.
The shell fits into the computer’s case with close tolerances; the cover fits into the
opening of the battery well. Developers who wish to provide a PDS card can obtain
shell components from Apple’s vendor, subject to the usual restrictions. For information
and authorization for obtaining the shell components, contact Apple’s Developer
Support Center.
PDS Card Connector 4
The PDS card connector is a 90-pin shielded connector. The connector does not sit on one
face of the card, but straddles the edge and requires contact pads on both sides of the
card. Figure 4-12 shows a section through the connector.
The PDS card connector is available as part number C-93-1817-54 from AMP, Inc. For a
specification sheet or information about obtaining this connector, contact AMP at the
address shown on page 40.
