yeah I started young.
in the 80s Fischer Price had a kids tape deck that had a microphone attached to it. so you could put a blank tape in it and then use the microphone to record whatever you wanted. the quality wasn't bad. so I'd make "mix tapes" for my friends of NES game soundtracks or songs off the radio. with the NES game tracks I would then try to sell the mixtape. songs from like the Batman game, Battletoads, Contra, Mega Man, etc. so I'd make the "first run" recording by holding the microphone up to the TV and then use my Dads stereo that had two decks to copy the "master" to other blank tapes and then sell them to my friends for like $1.
I'd then take the money I made and rent more games to rip the soundtracks and also buy comic books.
