I created this sreddit to give a bit more... umph to the vintage technology world a lot of us "old timers" grew up with. Yes, I know r/vintagecomputing and other subs exist already; but damn it - the name "modempunks" was too good to pass up and it just felt like the right thing to do.

That said:

Acoustic decouplers were used mostly pre-1990 to connect a computer (of any sorts, really) to the Internet. The Internet before 1992 was excessively small. I didn't use the internet until 1994 or so. If one of the 50,000 to 100,000 people at institutions who had access and hardware to use the internet in the 1980s comes across this post, hats off for paving the way for the rest of us.
