Bringing My Amiga 500 Computer Out of Mothballs
CP/M was the predecessor to DOS.
That VIC 20 almost cured me of messing with computers as well.
45 plus minutes to load a program from that tape with about a 60% success rate.
I also banged on the display TRS 80s at Radio Shack, but couldn't afford one.
My next one was a hot rodded 386 DX.
That one launched my IT career when I wanted to play "Doom" with more than 2 players and was forced to learn networking.
