@tommyyum I agree about the coolness of #SphinxOfBlackQuartz! It's just a shame the original poster got the quick brown fox sentence wrong: it's "jumps", not "jumped", otherwise it doesn't achieve full alphabet coverage.

Sadly I'm incapable of not being bugged by that detail, it's a burr under the saddle.

@jbm @tommyyum also, typically it was
“THE QUICK BROWN FOX JUMPS OVER THE LAZY DOGS BACK 1234567890 TIMES. “

And this phrase / characters, iirc, would test all angles of the type cylinder of a model ASR-33 teletype, including the numbers.
