Which brings us back to the original subject,
doesn't it? Current fancy
x86 still harks from the 8008 in that the old DAA is STILL there, although
heaven knows who still uses it (or why. I know the 4004 also had a DAA,
but I don't count it as the 8008 doesn't really descend from the 4004).
This story told us, that CPU's have bugs. x86 bugs are known because
x86's are widely used, and many are fixed. Your favorite CPU, 16032,
32016, z8000, 65816...... might have bugs that you don't know.
That's why my favorite CPU is x86 (besides VAX)
vax, 9000
