This setup is perfect for any retro computer with a dial-up modem, and will let you get connected to your home network through an intermediary. That computer — the client device — connects to an external host hardware modem, which, in turn, communicates through serial to a separate Linux computer. You can use something like a Raspberry Pi for that.
It isn’t exactly plug-and-play, and setting up your telephony software is going to take some know-how. But, the guide is pretty thorough. As far as your vintage computer is concerned, it will be talking to a dial-up ISP. But, that ISP is actually your Raspberry Pi communicating through the hardware modem. For that reason, it’s important to use a real hardware modem, and not a software modem. But, it’ll be worth the effort when you’re able to get an old computer connected for the first time in ages.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
