What was your first modem? Mine was a kit from Micromint in Long Island. It was around 1980 or so (I was about 13). My dad drove me to Cedarhurst, LI (I lived in Merrick, LI) to the Micromint sales office and bought this kit. It was an acoustic coupler, 300 baud kit, with an enclosure, a PCB and a bag of parts.
Very cool indeed!
Mine was a Livermore Data Systems model 71B 300-baud acoustic coupler. Man did I run up some phone bills with that. I still have it.
Mine was a 300 baud Novation J-Cat in 1983, connected to my TRS-80 Model III. Direct connect, and I wrote a simple BASIC program to dial out by pulsing the hook relay. http://q7.neurotica.com/Oldtech/Modems/Jcat.html Dave, I have a Livermore 76B: http://q7.neurotica.com/Oldtech/Modems/Livermore.html From a 1979 issue of Datamation: LIVERMORE DATA SYSTEMS76B Bell 103/113A-compatible originate-only type Up to 450 bps using FSK modulation Asynchronous, half/full-duplex operation Acoustic with RS232B/C interface Features alternate voice-data Over 4,000 sold since 1975 $300 Mike Loewen mloewen@cpumagic.scol.pa.us Old Technology http://q7.neurotica.com/Oldtech/
