>>11868242Its called modulation and demodulation, the oncersion of a stream of bits (1s and 0s) into noise. The spectrum or other computers that could use tales had a plug for a monno microphone cable and a mono inoput cable. Thes eplugged innto atape recorder, if you wanted to load something on the spectrum, you typically typed
LOAD "" and pressed enter
The computer would then start 'listening'. You pressed pay on the tape recorder and it plays a series of whistles sqeaks etc and when the loading sequence is reads an end of mile marker it executes the data loaded into memory from the tape. Small 48 or 64K games like on a commodore or spectrum do;t cvery little time. To save the same process, you write a program
like
10 print "practise saving"
20 Goto 10
and then
save "myprog"
and then insert a blank casette inn your recorder and press play and press enter
The computer generates whisles and squears representing the ones and zeros and its recorded to the tape as noise. You can just play the tape and listen and you will hear electronic beeps and squeaks.
The same techology was used to connect to the internet before you were born over phone lines by playing data convereted to noise over a phone line and the other end listening and recieveing (simplfyied).
here's a random youtube video showing you what it sounded like

, on the spectrum typically a graphical 'loading screen' would be rendered during the loading and flastinng bars around the screen acting as a visual monitor and represetation of the date being recieved
A lot of games in the very early era of computing on 1K to 64K machinens were typed in my hand, typically clones of stuff like cetipede or text adventure games. Magazines would publish them
