I have used a rotary dial phone to contact a mainframe computer. Once it started that warbling noise which you young whippersnappers think is the noise a fax machine makes, I had to then stick the handset into an acoustic coupler modem and hope that I did it fast enough for the handshaking to complete properly. It transmitted data at the blazingly fast speed of 300 baud.
I have used punchcards.
And paper tape.
And reel to reel, both for computers and for audio.
I owned (may still, haven't looked in all of the moving tubs, I don't remember if I kept it or not through the last couple moves) a Super-8 camera and projector.
I used to own a picture of John F. Kennedy printed on greenbar by an old-school impact printer. That I think either my dad ended up with in the divorce, or my mom threw out. But it hung in the front room in my childhood home in a place of honor.
I remember when transistor radios were the height of cool, and only came in AM. I had the ultra-cool
Panasonic Toot-a-Loop radio, which could be worn as a really large bracelet.
I mourn the loss of the
Bic Banana Pen. Which had a really annoying jingle.
There are, of course, a lot more, but those were the ones that kind of came to me.
