AirPort Extreme Card (2003)

The AirPort Extreme Card card replaced Apple’s original AirPort card in 2003. The first computers designed to use this card were the iBook G4/800 12-inch (original) and the iMac G4 1.0 17-inch (flat panel).

Apple devices with wireless capabilities after the AirPort Extreme Card had Wi-Fi as a standard feature built in to the architecture beginning in mid-2005. Beginning in 2006 with the Intel-based MacBook Pro, Apple used non-Apple-branded internal wireless cards (e.g., Atheros, Broadcom).

According to Apple’s AirPort Extreme Card User’s Guide:

AirPort Extreme Card Specifications
• Wireless Data Rate: Up to 54 megabits per second (Mbps)
• Range: Up to 150 feet (45 meters) from the base station in typical indoor use
(varies with building)
• Frequency Band: 2.4 gigahertz (GHz)
• Radio Output Power: 15 dBm (nominal)
• Standards: Compliant with 802.11 HR Direct Sequence Spread Spectrum (DSSS)
11 Mbps standard, 802.11 DSSS 1 and 2 Mbps standard, and 802.11g specification

Apple AirPort Carrier Card Adapter (1999)

The Apple AirPort Carrier Card Adapter (M8753G/A, 820-1066-A) is for the slot-loading G3 iMac (400MHz or faster). The “carrier card” allows a standard original Apple AirPort wireless card to be installed in an iMac.

At the time, wireless capability was not considered a standard computer feature so the iMac G3 not only did not include an AirPort Card, but it also lacked the internal port to accept it. Instead, Apple required this carrier to allow an AirPort Card to be added. The 802.11b AirPort Card was not included.

AirPort External Antenna (for Power Mac G5, 2005)

The Power Macintosh G5 from 2005 allowed a wireless network connection using an internal AirPort Extreme card. Since the Power Macintosh G5 had an external aluminum case, this external AirPort antenna was included.

The back of the Power Macintosh G5 included a proprietary port, the AirPort Extreme antenna port:

“AirPort Extreme antenna port—Connect the AirPort Extreme antenna to this port if your Macintosh has an optional AirPort Extreme Card installed.”

This AirPort Extreme antenna port is unopened in its original packaging.

30-pin Digital AV Adapter (unopened, 2012)

This adapter allows an iPad with the original 30-pin connector to be connected to an HDMI display and simultaneously charged. It is compatible with any iPad with a 30-pin connector, iPhone 4 (or later with a 30-pin connector), and iPod touch Generation 4 (or later with a 30-pin connector). Mirroring is supported only by iPad 2 (or later with a 30-pin connector) and iPhone 4s (or later with a 30-pin connector).

From my experience, the ability of an iPad to be mirrored on an HDMI screen is frequently misunderstood. Because an iPad screen is in the 4:3 aspect raitio, when it is mirrored on an HD display (16:9 aspect ratio or other wide format), some users are surprised that the entire external display is not “filled.” I have never been able to understand what the user is expecting—a ridiculously stretched version of the iPad display; a “zoomed” version of the iPad display with the top and bottom cut off; or that somehow the iPad will magically rearrange itself to fill a widescreen display, thus making it a completely new display and, therefore, not mirrored. Instead, the iPad works as expected and appears centered in the middle of a larger display with black bars on both sides (this is called “letterboxing”). If a user launches an app that uses the full screen, such as a presentation designed in HD format or an HD movie, the iPad fills the entire screen.

This 30-pin Digital AV Adapter is unopened in its original, somewhat beat up, packaging.
