    The Discrete-4017 kit, is a complete replica a of the CD4017 as used in many projects.

    All of the internal logic has been broken down to logic gates and then realised with only N & P type transistors (FETs)

    It is electrically a "drop in replacement" for the 4017 (although you may find the socket a tight fit)

    It can also run as a demo from a usb supply. Standing on its acrylic legs.

    Ideal for teaching logic, electronics, history and for retro enthusiasts.
