ASCII is set up for computers, in alphabetical order. Morse code has the most common letters as the shortest symbols.

or you know, ascii  
1100000 +  
1 = a  
10 = b  
11 = c  
100 = d  
etc…  
11010 = z
 
what I want to know is how do they make prints of those photos.

@Nomi_Slam Why “yes” and “64”? With only two keys and a space bar, creating English sentences is surprisingly easy.
 
There are three ways of pressing the two keys: left (0), right (1) or both (**). This enables a coding scheme somewhat like Morse code, where ** delineates each letter:
 
0* -> E  
1* -> T  
01* -> A  
10* -> N  
0000* -> H  
1011* -> Y  
11000* -> 7  
010101* -> .  
and so on. * by itself (without any previous 0s or 1s) would be a new line; carriage return is as in real-life typewriters, where the right hoof pushes on the carriage. The space bar (_) would be as usual, but pressing it along with the other keys would have some further effects:  
_ + 1 -> shift  
_ + 0 -> tab  
_ + * -> move carriage back one position
 
Of course, this typewriter having two keys was a result of rushed animation. Pony computer keyboards would have (say) seven keys, four on the top and three on the bottom, where each single key press and two-key chord would encode information.
