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. I had low expectations that it would work when assembled. I spent a few days assembling and soldering everything. I think the time was around Christmas and my new brother-in-law was over. He was a post-grad at university of Texas at Austin and had a computer account (don't recall the computer). It was time to test it. Me, my brother-in-law and my father were all standing around my TRS-80 Model III and this newly built modem, trying to call into the computer system at UT Austin. In those days, long distance calls were expensive. We must have dialed that computer 20 times while attempting to adjust the pots and make it work, unsure if it would ever work. I can't imagine what the bill was.

We all jumped for joy. The darn thing worked as advertised. Great experience and that modem served me well for several years until I upgraded to a Micromint 1200 baud "direct connect" modem before I went to college.

   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.
