    Of course you can, my boy, you just need to spend a few years going to a good educational facility and study Electronic Basics then Electronic communication and Design. After that get a few more years experience actually designing and building complicated circuits. Its that simple.

    This is a 300 b/s modem for Apple IIe used in the 80s.

    The 2 bigger chips are the EPROM and the 6850 ACIA.

    Modem modems are usually built with LSI chips and very much complicated than the modems used by early Apples.
    It would be cheaper to buy one than to build it from scratch. My Telco even gave me a free one when I subscribed to their service.
