Just curious (again!) if anyone is collecting the early modems used on
computers and what might have been the earliest commercial phone modem.
I have several devices that are called modem eliminators and I believe
these are basically serial cable boosters to increase the permissible
cable length. My guess is that the earliest modems were accousticle
(sp?) modems where the coupling was where the phone was laid onto the
modem rather than a direct connect to the computer. Was there anything
earlier or other type of device?
