Are you trying to make a pun with byte/bite relating to nibble? Because that's actually where the term nibble (referring to 4 bits) comes from, so I'm not sure such a pun even counts as a pun anymore. Or am I misinterpreting your comment?

I was not making a pun, though the terms of art in that area were clearly made to be puns. I was pointing out that the byte-size of a CPU is typically defined as its smallest addressable unit, so, I was confused to see a CPU using an architecture that works with half of that size; it does not make sense to me.

When did we stop spelling it "nybble"?

[zamadatix]

"Nibble" may well have always been in use by folks, and nybble may have actually come later. At the very least, references to each spelling being in use exist for the last ~60 years.

The first book match I get for "nibble" near "byte" is in the 1964 "System 360 Assembler Language" by Don H. Stabley uses nibble. The earliest match I can find for "nybble" in relation to computers was the 1968 "Encyclopedia of library and information science". Nybble (and likely nibble) itself doesn't seem to have taken off until around the mid 1970s https://books.google.com/ngrams/graph?content=nybble&year_st...

References to the coining of the term in 1958 of course don't provide a textual source.

I was wondering this as well. Probably when a new wave of people discovered the concept in the absence of the older wave? By contrast, "byte" has been in use continuously and widely.
