Well at least you didn't pay the original list price of $200 for it! But make sure you are a "Mac Lover", or you have to give it back, no matter how much you paid for it. :beige:
Actually the MacDialer software is the most important part of it. And MANY of us are interested in it. (Hint Hint). The phone itself doesn't have that great a review. You would be better off wiring your own phone equipment into the interface. Essentially, the software is a contact database which communicates with the hardware via the speaker port. Other than a limited contact list which logs the calls and provides for call notes, it is little more than one of those touch-tone pocket dialers that were so popular before cellphones, sending tone signals over a phone's mouthpiece to initiate and terminate calls via a GUI interface. In fact you may find this review of Borland's Sidekick which was the successor to the MacPhone of some interest. Essentially it offers a suite of desk accessories (addressing some of the criticisms of the MacPhone), without the inferior hardware of the MacPhone. However, it requires a modem for the phone interface, as does the Habadex application (another rolodex stand-alone auto-dialer program which was also sold with an interface box which plugged into the sound port in lieu of a modem). More than likely, without plugging in the MacPhone, if you hold your phone up to the speaker of your Mac, you'll be able to dial with the software alone.
But, both in 1984 and today, the MacDialer software has enormous value as some of the only useful applications which will run on the 128K and 512K. The hardware is superfluous. Congrats, and please do fill us in with the details once you get it and start using it! Especially once you make those all important backup disk images }
