[OT]I don't attach my ego to my work[1]. My two posts concerning a minimum standard
of conduct speak for themselves and are self-contained. There is no merit to
injecting it here.
Concerning the technical issue. I answered the basic question, "can a general
purpose processor be _welded_ onto the front end of a disk drive?" That was
the extent of my post. Steve looked at it another way, concurring with my
conclusion--it could not, relying on BOM analysis. My disagreements with
Steve over several of his peripheral "commentary" like assertions are clearly
moot in the root context of that discussion. To be fair, Steve extended my
comments, addressing the interface issue as well, considering the proposed
utilization of a general purpose processor as a potential implementation of
the more general and clearly more interesting to this group--proposed
interface. His discussion was abstracted interface-centric, mine was
implementation-centric.
I would just say I have not asserted that the disk drive industry would have
any technical problems designing a next generation interface of whatever
specs[2]... The truth is those interface issues are more determined by the
downstream OEM's and industry consortiums.[3] Of course lead time would be a
factor determined by the disk drive industry.
So what can _you_ glean from this mess? If you can't find discussion of a
proposed interface in an industry consortium forum, it is very unlikely to
become a reality anytime soon. OEM requirements for second source
availability strongly discourages independent, secretive interface
innovation.
I'll have to leave it there--I am very busy.

[2]My assertion is that they will not be employing a general purpose
processor under any circumstances.
[3]So in this limited context, Steve's assertion, that the front end interface
is decoupled from the back end electronics, is accurate. But the
implementation of the interface is not decoupled. It will be integrated into
the same chip as the core backend processor. This is an absolute.
