Borrowing Microphones -- Mark Anbinder <mha@baka.ithaca.ny.us> writes:

Purchasers of Apple's new low-end Macintosh systems will be surprised if they try to use a borrowed Apple microphone in the computers' microphone jacks. The Performa 475 and 476, LC 475, and Quadra 605 computers require the new PlainTalk microphone in order to record sounds using the microphone port, but don't include it. Microphones bundled with previous Macintosh models won't work, because the PlainTalk microphone has a longer plug (.75" rather than .5") and the old plug doesn't properly seat inside the new jack. The PlainTalk microphone is available as a separate item, in addition to being bundled with several of Apple's newer high-end Macs. The item number is M9060Z/A, and the microphone should be available from any Apple reseller.
