Well, it is 1995, our technology has had 3 years to ramp, and HP hasn't 
even begun their technology churn.  All that just to say that they are
about 5 years behind our technology curve.

	HP = 64-bits is bad news until we get around to offering a
	product.

	"PA-RISC has always had..." = Lets make it sounds like it's
	been around forever.

	What a bunch of horse puckey. HP, IBM, quit your whining!

    When I was at TI they did a short blitz about why LEDs were superior to
    LCDs in watches.  The reason for this was simple.  TI wasn't yet
    prepared to compete in the LED watch market at the time.  Similarly,
    when 7UP advertized "no caffiene" there was a lot of whining from the
    cola makers since they couldn't compete in the market.
    
    The *fact* is that HP (and IBM) are both whining because Digital is
    taking a stance that our competitors can't compete effectively with.
    Given this, it seems to me that the ad campaign about other companies
    whining is *absolutely* the right thing to do.  I think our next step
    should be to start quoting what our competitors are saying and POINT
    OUT that, true to our ads, they are WHINING!  Our customers need to
    *instantly* recognize the kind of BS as in .0 as WHINING!  But, I think
    we need to CONTINUE to point this out clearly and effectively.

    HP also say, "when the benefits outweigh the costs".  In most cases
    Alpha is cheaper than HP's products anyway and there does not seem to
    be a technical cost to 64-bits.

> and there does not seem to be a technical cost to 64-bits.

  Perhaps not, but it only takes one or two "assumptions" (on the
  part of some poor programmer 'way back in history) that a pointer
  and an int are the same to add up to a lot of non-technical costs.

  This isn't a long-term argument against a 64-bit architecture,
  but it's a fact of life that essentially *EVERYONE* who ports
  will have to face somewhere along the way.

  The H/P letter contains a lot of FUD, but like any effective
  propaganda, it's based on some kernels of truth.

3816.7SAS, a killer 64-bit app! Pound sand, HP!MSDOA::HICKSTFri Apr 21 1995 10:1816
    This is absolute crap.  (But hey, is anyone surprised?)
    
    The statement that no-one gets any benefit from 64-bit addressing is
    galling.
    
    Right now we have a KILLER application in SAS running on UNIX/Alpha. 
    Many mainframes are downsizing large SAS files, often greater than
    2Gbytes.  WE ARE THE ONLY GAME IN TOWN!!!  None of our competitors can
    access files >2Gbytes, and this business is ours for the asking.  We
    have two formerly hostile accounts that have had to hold their noses
    and buy AlphaServer 2100 4/275s running UNIX to run SAS... this has
    in-turn lead to greatly increased credibility and presence in the
    accounts.
    
    This is starting to fell pretty good!!!
    
3816.8LARVAE::JORDANChris Jordan, MS BackOffice Centre, UKFri Apr 21 1995 10:318
    Did HP say that NO ONE NEEDS 64 bit addressing??
    
    Did they THEN go on to say "If you do need 64-bit addressing, then
    PA-RISC can emulate it for you".
    
    Sound very like the IBM advert around the new Oracle/Alpha mainframe
    killer:  "Its not true, and even if it was true, its not fair!"

    No one needs 64 bit addressing.  Applications can't use it.  Software
    doesn't use it.  Users don't need it.
    
    But just in case they do, here's how we do it ...
3816.11Is it Software?CFSCTC::PATILAvinash Patil dtn:227-3280Fri Apr 21 1995 11:479
This is a good feeling, after a long time, HP and IBM cribbing about 64-bit
Alpha technology and in turn giving us good press (although they mean
otherwise). Does anyone have comments on the claim that "software layers, APIs,
compilers etc." are not (and will not for a while) utilize the 64-bits power
and hence there is no real gain in performance for "real" applications. Is this
an issue? Are we addressing it? How?

    Care should be taken to keep "cost" and "price" as separate issues
    when commenting on technology and who has cheaper products.  
    
    Price - determined by the lowest market price for a given "perceived"

Digital should run an ad similar to as follows:

"Our competition says that almost noone needs 64 bits.  And they're right.
But what about those who need 40 bits? Or 33?"


Even mapping a 1TB database as virtual memory "only" needs 40 bit addressing
to do so.

Really?  I don't have specific sales details, but there are now well over 
100,000 64b systems from Digital out there contributing over $3 Billion to 
Digital revenues so far.  All of the Digital Unix systems include 64b system 
software, so those users are already benefiting from 64b hardware with quite 
a clear future.  Someone buying 32b hardware today might want to think twice.  

Larry Ellison, CEO of Oracle, seems to believe that 64b applications are near 
enough to trumpet the extensive opportunities for the new 64 bit VLM (Very 
Large Memory) Oracle7 database product at our recent and well received product 
annoucement.

Slow down there guys, that's not what was said.  The biggest gain comparitive 
to a 32b system is due to the fact that you can use fast main memory instead 
of much slower disk storage for large database applications.  This is possible 
only after you break the 4GByte limits of a 32b system by allowing a larger 
than 32b FLAT addressing scheme.

Why quibble, both machines are available.  Run the tests and report the
results.  We have quite a list of performance results too.  Check the Digital
Web server  for performance reports, or any independant performance reporting
source.  If there is a performance degradation, customers will see it.  On the
contrary,  virtually every report shows our 64 bit systems on top, sometimes by
a little,  sometimes by a lot.  And we just introduced a new CPU that is much
faster and  isn't reflected in most of those reports.

That's right, it will take some significant time to get all the system 
software moved over to take advantage of 64b systems.  We've done this for 
Digital Unix and have been working on it for OpenVMS, soon to be available.  
There were some early issues to contend with, that's why we started back in 
1989, but then you'll find out too.  If we all wait for the market 
"to proliferate", there would be no leaders.

If we learned anything from that experience, it is that the industry is not as 
well tuned to the market as they would like to think.  The pent up demand for 
32b systems didn't take very long to swell considering that our 16b PDP-11's 
(one of the most popular 16b machines) was only in use for less than 10 years 
before the popular introduction of 32b computing with our VAX in the late 70's.

In the meantime, 64b, big memory machines sound pretty cheap compared to those 
slower 1M+ systems struggling to solve the problem now.  Those first 32b
machines  selling into a "market pull" as you say, did not immediately address
the lower  price bands either.  But if you don't need all that memory, you can
still get a  64b machine today for the same price as a 32b machine which should
allow more  people to sleep easier and only add memory as they need it.  It
doesn't hurt to  know that our current systems without big memory have been the
benchmark leaders  for over 2 years now so current applications run faster to
boot.

Yea, yea, yea, and overlays were great too.  How many customers like this 
solution?  I'll bet the number is far fewer than the currently available 64b 
applications by your count and moving in opposite directions!

Come on, "only cases" type arguments don't hold water with customers who all 
plan to be around years from now or they wouldn't be buying new computers
today.

Getting weaker and weaker here.  The price of the CPU chip is a fraction of 
the cost of the total system, and if you've already widened the busses as you
say,  then you've added much of the area.  Digital 64b systems don't cost more
than  HP 32b systems period, in fact, they're cheaper, so the point is empty.

That's fine.  You should decide what's best for your users.  But be careful
with  the "completely compatible" part, it's not as easy as you recall from
your last  transition.  And you're right, press releases confirm that ALL major
system  vendors have promised a 64b transition for their users in the near
future too.

Isn't it nice to know that you can buy a 64b machine today that runs literally 
thousands of those applications now and is becoming the platform of choice for 
developing many of the new and exciting, fully capable 64b applications for 
tomorrow.

  My responses after >>>. As far as I am concerned we should turn this around 
and attack HP for their limited systems lack of foresight and admission of not
having 64 bit addressing. I summarized this at the end. Hope this helps.

Clearly HP have been surpassed by the 21164 and the AlphaServer 8000 series. 
The arrogant and certainly pathetic "non-announcement" of the PA8000 at COMPCON
'95 underscores their lack of competitiveness in the market space and their
only response is nobody needs this until HP supplies it. The above text is
complete vindication of our strategy and a lamentable commentary on HP's
offerings.

    	Before taking the information within this response to the market,
    we subject it to further analysis. It appears to me that there are some
    problems within.

    Let's not wear ourselves out prematurely patting ourselves on the back. 
    Although the HP FUD letter and our responses give us some great
    ammunition, let's use the messages carefully.
    HP has historically beat Digital by providing superior support,
    dedicated and trained sales teams focused on customer need, superior
    executive level relationships, a long and distinguished record focusing
    on the open systems market, and a huge list of loyal ISVs and
    customers.   Furthermore, their current marketing strategy is to take
    our strength (price performance) and use it against us.  If we respond
    to the HP FUD by just saying we're faster and cheaper (without at the
    same time strengthening our alliances, marketing, support, and focus)
    we will get beaten more often than not.

    I think the best response to this FUD would be to line up testimonials
    from customers that are successfully using Alphas.  Use some of the
    technical arguments presented here as a basis, but let real customers
    drive it home.  I've actually been expecting something like this from
    Digital ads.

Send your customer a video tape of the TurboLaser announcement with
Oracle.  That tape will answers most of HP FUD.

3816.26More applications and seed/demo unitsLEMAN::JOSHIFaster than a Tachyon; Easier to FindThu Apr 27 1995 19:3510
    I am seeing pretty much the same story right across Europe.
    Sometimes our customers (US based and European) do dance to the HP tune
    and we need to better articulate and be more literate to challenge the 
    aggressive HP stance. 
    
    For us to make them really suffer, and double our revenues in the near
    future, we're going to need more applications (like SAS) - and more 
    seed/demo units.
