they claim FIRST ACOUSTIC COUPLER IN 1970.... nah... GE 1968 My customer has an Olivetti terminal that he wants to use on GE Time-Sharing Service. How much does our acoustic coupler cost and what is the rental fee? The TDM 114 acoustic coupler rents for $25 a month (including maintenance by service shops) and sells for $395. The TDM 115 acoustic coupler costs $495. Aug. 1968 GE service Note - time share etc Multi-Tech says... 1970: Dr. Sharma founds and incorporates Multi-Tech Systems, renting new office space in the basement of the Schneider's Drug building in Minneapolis. He sells the world's first acoustic coupler to Professor Schmitt, inventor of the Schmitt trigger, for $300. worlds first? hmmm... Not. Remember too the Deaf had acoustic couplers prior to 1970 also!
