My best friend is responsible for both of these. The #acousticcoupler modem works (150baud) though it needs a few capacitors replaced.
@pfriedma 150 baud! And I though my first us robotix modem was slow at 33.6k! I love seeing old tech 
@alex@pfriedma totally practical idea: an acoustic coupler modem that would accept a modern smartphone so you can retrocompute on the go (not sure what modern voice compression algorithms would do for the connection, though!)
@alex I swear I saw an artist (maybe from Birdsite?) do a smart phone acoustic coupling modem render a few years back.
Funny enough, if I turn my phone volume up loud enough, it will work as is. I've got an asterisk voip set-up with extensions that emulate bell102. One number opens BBC in 'wc', for example.
@alex@pfriedma oh cool! I guess modern phones are much louder than the ones that the couplers were originally designed for
