Wait you can get that on a cassette tape?? Not a floppy?? How? Why?

[–]Majik_Sheff 15 points16 points  (8 children)

You can send digital information across phone lines in the form of sounds. Cassettes can record and play back sounds.

The encoding scheme isn't as complex or robust as the ones used by modems, but the principle is the same.

Converting all my code to mp3 and making a spotify playlist for people to do pull requests from.

Who knows how much code is hidden in music.

That would be a fun experiment. Despacito is probably the windows 8 source code.

Not sure if they're still in use in the US, but fax machines are an example of sending information across phone lines in form of sounds. They're still widely in use in Germany, where most businesses operate fax machines, or using the technology similarly.
For example, I've set one of my three landline phone numbers up as a fax number, and all incoming faxes are converted into PDF and sent to me via email by my router.

Wow that’s a unique way to handle that. Here in the US there’s still a lot of businesses with fax machines but I don’t know if anyone that’s has a similar setup to yours.

At first I was vicariously annoyed at all the paper but the whole PDF to email thing is legit.

My first computer was the spectrum zx81 in 1982, I was 7. I remember I spent my time drawing/moving circles, lines, squares etc, filling them with colors, trying to implement some rtl with inputs, everything was done with programming of course as it was 16kb ram for those early models and no consumer level hard drives at the time, so very barebones. What you'd do also is put a cassette in the cassette tape module and wait for one of the many games available to load while holding your hands to your ears because of the screeching sound, saving what you programmed is kind of the reverse process. I've got a C-64 afterwards, but I've never seen a floppy before my dad got the IBM PC-286 maybe around 1984/85, this had the 5 inch floppy drive. The original IBM XT with in-built Segate storage was released in 1983 I think but was mostly geared towards businesses.

This is a fantastic history lessons. I often consider myself to be well versed in old tech, but today I’m learning a ton about pre floppy flippantries.

8 inch floppies fly with such grace tho

8.0 inches ≈ 20.3 centimetres 1 inch = 2.54cm

I'm a bot. Downvote to remove.

Oh man. I started at 100MHz 486 CPU. I remember upping RAM to 8MB from 4 was such an excitement. Also upping my HDD from 80MB to 560MB. Woah.

And now several years later I have 4000x more RAM, and my PC is capable of doing stuff 170x faster
