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.
yeah that’s good stuff…I messed up my crystal solder job enough that the rest of the dialer circuit wouldn’t work…I tried a tape recorder instead but using that just got the at&t operator to harass me
