Red box - Lemmy.World

Read an article about building a Redbox either on the 2600 Usenet group or some other hack/phreak BBS probably around 1993. Went to radio shack the next day to buy the tone dialer and crystal. I messed up the solder pretty bad but it still works to this day. https://en.m.wikipedia.org/wiki/Red_box_(phreaking) [https://en.m.wikipedia.org/wiki/Red_box_(phreaking)]
