I played on Silent 700s when I was kid. My father would bring one from work every now and again and I would be allowed to play on it... a bit anyway (I was ~10 at the time). I remember being in awe at how sophisticated some things could be... that you could actually put the telephone receiver in a couple of rubber cups and the machine could "talk" to a remote machine far away. Wonder of science that. And no, I'm not saying that sarcastically either! The phone we'd put in the acoustic couple modem was itself still a pulse-dialer with a cord (cordless phones still weren't generally on the scene just yet, though DTMF dialing was a thing, a newer thing, but a thing).
Between that and the copy of 101 BASIC Computer Games book I had (and still have) from that era, my career was really started unbeknownst to me.
