Not blame, you are making a chicken out of the feather... a mistyping 
can occur, I was just wondering why you where so consistent about it.

BTW, as for the HP appnote, you got the wrong one. I was refering to one 
written for HP 5371A and/or HP5372A and not the HP 5370A/B. I think it 
is in the App note 358 series. Regardless, I have not spent quality time 
over it as it does not address issues which is particular useful for me 
as I don't do disc drives and rarely to those low rates of bitstreams.

Cheers,
Magnus
