Applications

The PM14400FXMT was marketed specifically for Apple Macintosh users during the early-to-mid 1990s, when external serial modems were the standard means of dial-up internet access, bulletin board system (BBS) connectivity, and fax transmission on the Mac platform. Macintosh computers of that era used the DB25 RS-232 serial port as the primary modem interface before USB became standard, and external modems like this one were a common desktop accessory alongside the Mac Classic, LC, Quadra, and early Power Mac lines. Practical Peripherals was a well-regarded modem manufacturer of that period, producing both Mac-specific and PC-compatible external modems. Today this modem is sought by vintage Mac enthusiasts, retro computing hobbyists, and collectors maintaining period-correct 68k or early PowerPC Macintosh setups, as well as anyone running legacy communications software that requires a hardware serial modem.
