| INCORRECT | It looks like Pin 2 ("PSW"), the Power Switch pin on the ADB connector, must also be used on the desktop Mac G3 (Apple P/N M6141LL), since there is a "soft" key on the Apple Extended Keyboard that is normally used to start the computer. This is a guess: that pressing that keyboard switch momentarily connects Pin 3, the +5V pin, to Pin 2. If true, this would make the statement "Pin 2 is used only in the Macintosh II family, Quadra 700 and 900, and PowerBook series. Unused on all other models." on your web page incorrect. | NOT APPROVED |
| INCORRECT | My previous message to you assumed the Pin 2 would momentarily be connected to pin 3 to turn on the computer; that was wrong. Below is from Apple's article on the ADB protocol at this web address: http://developer.apple.com/legacy/mac/library/technotes/hw/hw_01.html "Soft Power On Macintoshes with software power control, the machine can be turned on by an ADB device. This is accomplished by momentarily connecting pin 2 on the ADB connector (reserved) to pin 4 (ground). Pin 2 should be kept grounded until pin 3 (+5 volts) comes up to power, letting you know that the machine has actually come on. Some Macintoshes do not have soft-power capabilities; on these machines, grounding pin 2 will have no effect." | NOT APPROVED |
