Originate/Answer Modem

MFJ Enterprises, Inc., has introduced the MFJ-1230 Originate/Answer Modem. It looks and is used like an acoustic coupled modem, but it uses an inductive coupling technique for receiving. This gives more reliable data transfer by eliminating errors caused by room noise, vibration, and a host of other acoustic coupling problems.

This Bell 103 compatible modem operates 0 to 300 baud, features half and full duplex operation, and is crystal controlled for very high stability. It provides TTL and CMOS inputs/outputs as well as RS-232 compatibility. This allows easy interfacing to nearly any computer with proper software. Also, input/output ports for a cassette tape recorder let you save your transmitted data and load it back to your computer or retransmit it later.

The black, low profile, all-aluminum cabinet measures 4 × 1½ × 9½ inches. It is simple to install and operate and is compatible with nearly any standard data terminal or personal computer. It is made in the USA.

An Apple version (MFJ-1231) that plugs into the game port comes complete with soft-ware. No serial interface board is needed.

The MFJ-1230 and MFJ-1231 Inductive Coupled Modem is available from MFJ Enterprises, Inc., for $129.95 and $139.95, respectively, plus $5 each for shipping and handling.

MFJ provides a 30-day money back trial period. If you are not satisfied, you may return it within 30 days for a full refund (less shipping). MFJ also provides a one year limited warranty.
