Webster's 1913 Dictionary
\X\ ([e^]ks).
X, the twenty-fourth letter of the English alphabet, has
three sounds; a compound nonvocal sound (that of ks), as in
wax; a compound vocal sound (that of gz), as in example; and,
at the beginning of a word, a simple vocal sound (that of z),
as in xanthic. See Guide to Pronunciation, [sect][sect] 217,
270, 271.

Note: The form and value of X are from the Latin X, which is
      from the Greek [Chi], which in some Greek alphabets had
      the value of ks, though in the one now in common use it
      represents an aspirated sound of k.

Thus, the abbreviation 680x0 stands for 68000, 68010, 68020, 68030 or 68040, and 80x86 stands for intel 80186, intel 80286, intel 80386 or intel 80486. A unix hacker might write these as 680[0-4]0 and 80[1-4]86 or 680?0 and 80?86 respectively; see glob.
