I wrote a couple of programs for a Control Data Corporation (CDC) 6600 back in the early '70s. I recall that the smallest addressable unit was a 60 bit word (though there were special instructions to pack and unpack some size of character -- was it 6 bit?) Bob Correct, except that there

I originally thought could be a way of storing Unicode text in databases. However, after some thinking, I decided that idea was completely bogus, so I though to turn it into a joke for geeks. But it wasn't even amusing, so it went in the Deleted Items folder. However, I see that illogical ideas

I was hoping someone with more detailed memory would mention this, but since not, and since it is a contender for having one of the largest minimal addressable unit (other than microcode storage): I wrote a couple of programs for a Control Data Corporation (CDC) 6600 back in the early '70s. I

Thanks for all the interesting feedback. Now let me ask a slightly different question: Prior to Unicode and ISO 10646, what were the smallest and largest size code units ever used for representing character data? In the various responses, there was reference to 6- and 9-bit character

Morse code uses a one-bit scheme, if you will, or a small number of codes (short/long sound and some 3 or 4 standard lengths of pauses) depending on how you look at it. Well, either you say that Morse code has a character set of three characters: SPACE, DOT, DASH, meaning a two-bit encoding is
