1976.1 | to announce or not to announce, that is the question? | STAR::ABBASI | i^(-i) = SQRT(exp(PI)) | Fri Jul 10 1992 03:10 | 16 |
| I dont completely buy the fact the sales of VAX is low because of Alpha
announcements, example, every one knows that Intel 586 is coming out
in production 6-9 months from now, and its is at least twice as fast
as 486, but that do not stop people from going out and buying 486's and
even 386's PC's, right?
actually, VAX sales is not low, sales of VAX's are doing better now than
befor ..(price cuts?), I heared this in a meeting 2 days ago ..
any ways, many other companies do announce more advanced versions of their
products long ahead of time (dont they?), but that ought not to stop their
customers to buy their existing products (right?) otherwise no one will
buy anything, because there will always be better/faster versions of the
products coming out the pipe..

1976.2 | never forget OSBORNE! | TOOK::TBOYLE | | Fri Jul 10 1992 04:38 | 24 |
| Remember when Osborne announced his new machine and went bankrupt in 3
months? The new machine was not ready yet and the sales dived.
Symbolics did this when they announced IVORY also.
One problem with VAX has been that the price/performance was has been
so low, that people have been buying because they were forced to and
had no alternative. FIgure this, VAX 9000 has recently been the only
way to buy 90 vups and it costs $500,000. Well Alpha promises 100-150
mips in a deskside system at an order of magnitude price reduction.
What would you do?
I'm glad the VAX sales are picking up. This is a good sign. There is
the VAXstation 4000-60 at 12 vups on the desktop, pretty decent. And
its followers are faster I am told. I hope we push these successfully.
On the 486, you don't have toi wait for 586 because 486 is plenty fast,
however, with the VAX, its been that the performance has been a dog
giving you a reason to wait for both better speed and lower prices/mip.
I hope we can market are newer vaxes that are around, they are fast now
and thank goodness we have them now!

re .0
I agree with some of what you say. However, it is SOP for companies
to announce products before they are ready...it happens all the
time, and everybody does it.
It would have been extremely difficult to keep Alpha under wraps
for any significant amount of time if only because of the great
amount of software work that needed to be done, such as working
with CSOs to port over existing applications. And Alpha is not
"just another VAX", it is an entire new architecture.
Has the announcement cut into VAX sales? Probably. How much?
Don't know. Is it the sole cause of headcount reduction? No.
Will Alpha solve all of DEC's problems? No.
This waiting around to see who will get cut next is demoralizing
and depressing. In my opinion, the company should just do it and
get it over with, so that people can get on with their lives
instead of having to live under the Sword of Damocles, as you
suggest. Waiting just adds to the stress and tension for everybody.
That layoffs will occur is a foregone conclusion; we can only hope
that fair and objective criteria are used to select those who will
be TFSOed.

1976.4 | ALPHA is irrelevant | SGOUTL::BELDIN_R | All's well that ends | Fri Jul 10 1992 09:40 | 17 |
| The downsizing of Digital did not start AFTER, but BEFORE the financial
losses. In 1985, Puerto Rico reduced its workforce to kick off the
process. In 1988 and 1990, we did it again. And now we're closing up
completely.
The fact is that you can't blame our losses on anything other than
bloated costs and reduced demand for our products. No recent action,
such as announcing ALPHA has affected either of those. The bloated
costs are being attacked by eliminating the cause of them, people whose
jobs add cost, not value. By the way, management is responsible for
these unneeded jobs, not the people doing them. If and when your job
is eliminated, its your boss (and/or his boss at some level) who
failed, not you.
Apparently, nobody knows how to increase the demand for our products.

I'd like to have a 486-class machine for what I'd like to use it
for, but I don't have to have it today. Given what is probably going to
happen to the prices of these systems once the 586 is out, I'm waiting.
I, for one, don't mind being a generation behind if that saves me a lot
of money and only incurs a wait of a half year or so.

> Apparently, nobody knows how to increase the demand for our products.
This is probably worth a topic all its own, but it probably belongs in
MARKETING, which I don't follow.
I've often wondered if the above isn't a big problem for DEC. When I was
an OEM 15 years ago, I always found myself selling to my clients on the basis
of what I could conceptualize for them above and beyond what they thought
they needed. Granted, customers are almost infinitely more computer literate
than they were in the mid seventies. But I still think that DEC may suffer
from a mode it developed in its formative years, where the equipment sold
itself and DEC didn't have to do much in the way of imagining new uses.
Yes - we've got lots of new innovative software and hardware products to
address a variety of horizontal and vertical markets. But do we have anyone
who bothers to think about how we could actually "create" demands for
our products?

One of the most closely guarded secrets within IBM is new product data - simply
to keep from killing current sales. They noticed a long time ago that when they
announced a hot new machine the current machines couldn't be given away.
Qualifier - I think this phenomena is well known throughout mid-frame and
main-frame makers. I'm not so sure you can extrapolate to the desktop the
same situation - we're dealing with significantly different markets and
cost.
Do I think they could have kept alpha under wraps? No. But the really should

| Lighten UP!
The February announcement was for the Alpha Chip. We are, for the first time
in my memory selling the CHIP to third parties. In the chip business it
is customary to announce the chip shortly before availability of sample
quantities. Since we are a manufacturer of systems it is necessary for
us to make some comment about what the new chip would do to our product
line. The problems were caused by too little information be given out. I think
that if we were more forthcoming about VAXfutures for July and beyond
in February we would not have had quite the negative impact that it did.
There are also anti-trust implications for this. Microsoft has been sued
more than once for supposedly giving its internal product developers
(Excell...) access to new versions of Windows
prior to public availability to the likes of LOTUS and Borland. They haven't
lost any to my knowledge but the conservative legal department at D.E.C will
no doubt be pushing for public annoucement and sale at a point that is
defendable if in the future Alpha becomes widely used by third parties and we
get sued. It sets a precedant for good behavior.
Regarding the Q3 loss. There was curious statement in the press release that
up to $200M of the loss was due to foreign currency fluctuations. This
is curious in that there is a group that is supposed to manage our risk
associated with foreign exchange. Guess they didn't do so well.

What's a couple of VUPs between co-workers? :-)
A little more seriously though, the 4000-60 is a *very* nice
machine. I received mine a few weeks ago. However, for those of
us who own a 4000-60 and have co-workers that don't, it should
be sold with some type of industial cleaner and a towel to take
care of the finger prints and drool.
Even more seriously, since the 4000-60 is such a great machine,
I can only imagine what the 4000-90 can do. I believe these
machines should be an excellent example of hardware that "sells
itself". I've heard established external customers complain about
VAX worksation speed in general for several years now so the demand
is out there. The real question (he asks aloud) is "will the 4000-xx
machines will ever have the chance to become established in the
market?", particularly considering the marketing & sales value of
"word of mouth from a satisfied customer" and the amount of time
it usually take to establish that type of reputation.
If the demand for powerful "VMS functional" systems exists, the
supply exists and the cost per MIP/VUP/SPECmark (or whatever) is
"acceptable", what else would be considered a major factor in
dwindling sales? My bet would be stability, depending on your
particular attitude it could be stability in the product OR it
could be stability in the producer. Both are probably very major
factors in the current state of DEC business and I'm don't see
how arguing over a little nit here and there will fix that type
of thing.
My vote is for a well thought out, common sense, consolidated
plan for a future, *not* a mish-mash of messages, products and
empire_building_power_hungry_chiefs that jump all over each other.
My 2 cents...

And there was a PDP-8-compatible chip, not actually
manufactured in our plants but I assume licensed by us (the
later DECmate-n products used it).
(I am assuming that they were actually sold, or at least

However, no it did not eat up sales.
PDP-11 was booming and a late-generation PDP-11 was taking off.
VAX was like firing the second barrel, it went up as well.
Back then, of course, DEC, the computer/high-tech industry, and the
global economy were in more growthful shape.
It hardly seems relevant to the present situation:
- VAX 'in decline' -- or at the very least perceived to be

| Re .19 (Tom_K):
When we announced the VAX-11/780 system (the first of the family), we
announced that it had "native mode" and "compatibility mode" features:
the latter was a PDP-11 m ode, where it would run RSX-11-based PDP-11
software. This was done because:
a) There was little available native-mode VAX software; and
b) because the PDP-11 was _immensely_ popular at the time, and the new
computer could be considered an extension of it (the "-11" in the
model name was to stress the "elevenness" of the new line).
If one was contemplating buying a new machine to do PDP-11 applications
with no thought of developing new native-mode applications, the
price/performance advantage wasn't there, and sticking with the older
product was a better alternative. Also, that first VAX computer was
much bigger than any available PDP-11 system (the PDP-11/70 was the
closest, and other factors were affecting its sales). A large
percentage of PDP-11 computers were OEM devices, which called for
smaller UNIBUS and Q-bus based systems.
In short, the new systems complemented the old, and were not a direct
competition for most markets.

| re .27
SPEC is not a VUP by definition. Yes, SPECmarks are relative to the
CPU speed of an 11/780. But that is where the similarity ends.
VUPs are a DEC measure of CPU speed based on several internal
benchmarks. It compares VAX systems to other VAX systems. It is a
Digital measurement.
The SPEC89 benchmark suite is a set of 10 benchmarks put together by
the SPEC consortium. This is a group of a bunch of vendors - including
DEC - who work together, sort of, to come up with a set of benchmarks
that measure CPU performance across architectures. So you can compare
the CPU performance of SUN, HP, DEC, brand-X systems based on
SPECmarks.
Until a couple years ago, a SPECmark turned out to be roughly a VUP.
Then the vendors figured out a way to optimize some of the SPEC tests
and everybody's SPECmark numbers inflated. Except ours. We did not do
the same optimizing initially because these made the benchmarks less
realistic. But we started with the products announced in Oct 91.
This is where the Kuck preprocessor comes in.
Meanwhile, the SPEC consortium got together and decided that they would
change the SPEC suite of benchmarks because everyone had optimized the
initial set to the point where they were misleading. So the original
SPEC suite is now called "SPEC89" and the new suite is "SPEC92".
But everyone does not report SPEC92 numbers yet.

The 11/74 was never offered for sale. Though a few were built and I
believe there was a field test. The RSX development people shut theirs
down only a year or so ago I believe. I believe it would handle quad
processors not just dual. And it was SMP which is why I was surprised
that the 11/785 was ASMP. It was fast and would very likely have hurt
VAX sales.

The big edge the 11/60 had was that you could write your own micro code
(ie add instructions) for it. There were not that many people who could
or who wanted to take advantage of that. Digital used it internally to
emulate the PDP-8 for PDP-8 software development BTW. If we'd had some
good micro code packages that accelerated specific applications or types
of applications it might have sold better.

As I recall, the 11/60 was due out well before the 11/780, but was late
so came out at around the same time. It had an internal tag of "PDQ"
attached to it - a pretty d****d quick machine - and there was some
comment around that the implementation project was also supposed to be
pdq but wasn't. It had some cache and user-programmable writeable control
store, but only 128K of memory, max. Ed. Services probably bought them
to be able to host courses on wcs.
Then, though, Digital was prospering enough (and there was little enough
competition in the market) that people could laugh the 11/60 off.
The aspects of innovative technical spec. but late delivery and failure
to match main trends in the market, sound familiar, though...
On .19 and .20 and how the VAX announcement was handled, I seem to
remember (working for a customer by end 1978) that the announcement was a
bit confused, and caused comment that "Digital had got it wrong" (high
cost, limited memory, limited storage, limited applications migration,
limited compiler availability, small page size for VM, etc). Of course,
Digital got a bit larger after that. But some of the comments were
probably accurate all the same. Not sure what that shows, apart from
pundits having limited relation to the marketplace, and excellent
engineering being pushed into products that were sometimes less than
excellent, but succeeding anyway through market presence.

of the cake (there's still only three - minor - firms
Cray, Kubota and Olivetti ) ???

The ALPHA announcement only exacerbated the real problem: the
trend in the industry called downsizing. People are moving to
cheap, industry standard platforms, linked together in client
server arrangements. VAXes aren't part of this trend.

SPECmarks are computed by comparing current benchmark times with 1989 reference
times from a VAX-11/780, which probably would rate at 1.2 or 1.3 today due to
compiler improvements.
VUPs are calculated by comparing the new machine with a VAX-11/780, both with
the most recent software.

The 11/74 had two changes over the 11/70. It supported 4 processors, and it had
microcode and data path support for the PDP-11 Commercial Instruction Set. CIS
did not buy much over a better compiler for the base machine. The MP hardware
had some technical problems due to the physical aspects of connecting 4
processors to shared memory.
The 11/785 was a Schottky TTL version of the 11/780 with the cycle time down to
133 ns. You must mean the 11/782, which was sold as an ASMP. The hardware was
symmetric in that all memory (MA780) was accessible to both processors, but
each processor had its own SBI. VMS did not support SMP at that time. The
interesting thing about the 11/780 is that the SBI would have supported another
processor, but the 780's SBI interface logic was designed for it to be bus
master, therefore you could not plug 2 CPUs into the SBI.

1976.40 | RSX-11M-PLUS for Multi-processing | SUPER::PARMENTER | Nouvelle blague | Tue Jul 14 1992 10:14 | 15 |
| RSX-11M-PLUS was designed as the operating system for the multi-processor
11/74. The 11/74 was no dinosaur. In fact, it blew the doors off the
"11"/780. The decision to cancel was very upsetting. It was my melancholy
duty to remove all references to multi-processing from the operating system
documentation.
The multi-processor wasn't very fancy. Instead of one processor on the
Unibus, there were four. (simplified explanation) It worked fine and would
have materially affected VAX sales. I believe we made the correct decision
in not selling it, although at the time the excuse was that training and
field service couldn't ramp up to supporting both the VAX and the 11/74 at
the same time.
There were multi-processor hooks in the J11 chip and we sometimes fantasized
about that.
