One more out of bsd-games, because … well, just because. And this is a three-fer. Here’s ppt
first.
If you’ve been in the computer game for a while you’ll recognize a strip of paper tape, cleverly rendered in ASCII characters. ppt
will translate to image and back, as you can see in the screenshot above.
Now bcd
.
Keeping with the 1960s-70s computer motif, bcd
translates — only, I might add — from text to an ASCII rendition of a punch card. Anybody here remember punch cards, besides me? Anyone? Anyone … ? π
Last but not least: morse
.
By now you probably have an idea of what morse
will do, if logic follows in this post. As you can see, morse
will use the “dit-daw” notation, or better, the dot-dash notation. And like ppt
, it will convert back and forth between its product and the original string.
So … aside from nostalgia, what use are any of these, K.Mandla?
Well, again, you’re the best judge of that. I suppose if you need some sort of bland cryptographic effort, it could work that way. After that … I’m out of ideas. π
Speaking as an Official Old Git, I clearly remember 80 column punch cards using Extended Hollerith code. I remember little beyond that and have no nostalgic need to revisit them!
