What a wonderful "blast from the past".
I loved it when the announcer asked "Why did you buy a computer?"
Great stuff. Thanks!

Even used a rotary dial type phone to call up the computer, I'm pretty sure I was using a touch-tone phone back then. Come to think of it, I don't think I've ever owned a rotary dial phone, though we used one at my parents house while I was growing up in the 1960s & 70s.

This got me wondering since I couldn't remember.
Wikipedia says that by 1979, push button phones were gaining in popularity, but in the 80s they were the majority.
Amazing changes in our world.

The first 300 baud modems for the Commodore 64 were designed to plug into the earpiece jack of a Western Electric/Bell System phone so the phone's electronics would match the signal to the phone line.
The problem was that my touch tone phone at that time didn't have such a jack - it was hard-wired, and like most of that era still leased from the phone company. So I found an older rotary dial phone and wired the cable directly to that circuit on the other side of the hook switch so the modem could dial.
By the time their 1200 bps modems arrived Commodore had gotten regulatory approval for direct connection to the phone jack and I could retire that setup.

I heard, not sure if correct that the modems that were coupling with the phones (audio style, not electric) was the result of the monopoly the phone company had and because they owned the equipment (phone and lines) and they didn't allow a direct electrical connections.

True, but by 1984 when the first commodore modems arrived, Bell had been broken up and you could finally buy non-Bell telephones. Commodore just hadn't passed the compliance tests for direct connect to the phone lines. I don't know that they tried. It was easier to inject audio into the existing (bulky) matching transformer of a working phone than create circuitry to protect the modem from the unfiltered ~ 90 volt ring pulses on top of the 48 volt DC basic loop connection. I assume they then piggybacked on the new phone manufacturer's designs by the time the 1200 baud 1670 replaced the VICModem 1650/60.

I was never really aware of that. Thanks.
