Thank you for the clarification.
My take away is that before some nebulous point in time (circa IBM's
360) a "byte" could be a number of different bits, depending on the
computer being discussed. Conversely, after said nebulous point in time
a byte was standardized on 8-bits.
Is that fair and accurate enough? - I'm wanting to validate the patch
before I apply it to my mental model of things. ;-)
