Sound of data from old computer to tape recorder

Hear data transfer to tape from 1980 era Ohio Scientific home computer. Also see a 1974 Texas Instruments calculator at work. See my own computer journey from grade school till now.

wow load annoying sound....lol i bet it took some getting used to ...to have to deal with the noice everytime you used a computer that used a tape recorder

[theslowlane]

When I was transferring data, there was no sound. It went to the tape recorder through the cable. Wondering what it would sound like to play back the tape, I listened to play and got the sound.

I have one of those Radio shack cassette recorders!exactli like yours.

It is from the 90´s? I got mine at a thrift store for 2bucks.

I forgot when I got it, but I think early 90s.

Beautiful, beautiful industrial byproduct in the form of sound.

Reminds me of IBM by T.G.

The data sounds are called Frequency Shift Keying. I know this because I still use an Ohio Scientific.

You know, I was born in '91, but my father always had the older computer models and a tape recorder or two. I never did get the drive to save to it, but it's cool to see you did what I wanted to do in the first place!

I am able to decode all those bits of data by ear! And if you believe that, I have some swamp land in Nevada to sell you.

High frequency = 1, Low Frequency = 0. I used to have one of those on my old commodore vic-20 back in the 80's and used it to store programs I would either write or type in from a magazine. One time, I recorded over one of my mom's tapes... She put it in the big stereo tape deck and was expecting to hear the rolling stones and instead got the 0 and 1 medley.... Yeah, that was good for a weeks worth of grounding.. LOL

That's the calculator I had back in 1973-76 when I was stationed in Germany.

Data is still stored on audio formats.  CD's and DVD's are still used.
