#Subler for pc software#

This setup is the same, with some software differences, that the one used to connect a Palm to the Internet. The funny point is that I got mine in its original box, including the “driver” for the computers of that time (IBM PC, Atari, Apple II, etc.) : a few pages of BASIC for each machine to enter manually.įor the modem part, I made it simple : a desk phone, a phone line simulator and a Raspberry Pi equipped with a modem. In my case, I found a RS Coupler 9201, which is a priori a clone of the Novation CAT. In the early ’80s, a frequent modem was the Novation CAT, sold on other brands like Apple (for Apple II), Atari, etc. In practice, we can expect about 30 bytes/s in good conditions… The speed level can reach up to 300 bauds, or 300 bits/s in theory, but in practice much less, since the protocols need a few bits for the signaling. This technique has two drawbacks : the communication is audible, and a little loud sound in the room breaks the connection. Then the modem emitted sounds that were sent to the modem in front, and the latter replied. How does it work ? The first modems used to work in “acoustic”, that is to say, the number was composed on a real phone and then the handset was placed on the modem, on a dedicated location. If I did not find a modem that old, I still finally found an acoustic model that dates from the early ’80s. And a little later, I saw a presentation introducing a guy who logged on with an acoustic modem dated from the ‘60s.
