See RAINBO::FLG:[WASSER]MACINTOSH note 2072.10 for a brief summary
of the NeXT machine.
I've seen conflicting prices, but I think the real price is more
like $11,000. The $6500 price is only for universities, where the
machine is being strongly marketed as a next generation Unix
workstation. In fact, at first, the machine will ship only to
universities.
I'd say that the NeXT machine has virtually no effect on the Amiga,
which I consider to be a high-end home computer or low-end
graphics/video machine. The NeXT could really put the hurt on the Mac
II, where it could have a clear cost/performance advantage. And don't
you think that would make Jobs very happy?
I would hope that a next-generation Amiga would be more interesting
than Jobs' offering. If you consider how advanced the Amiga was,
architecturally, over the competition (128K Macs and 64K Pee Cees) in
1985 than the NeXT doesn't seem quite as revolutionary. There ARE
numerous innovations, however.

Here's what you get for $6500 (student discount). Sounds like a
good deal! This is what the next Amiga should be, but with a COLOR
monitor of course !! If you have not seen this machine (it is totally
black, the cpu box is a 1x1 foot cube with a slot in the front for
the OptDisk <look really ugly there>.)

Subject: Trip report: NeXT Introduction
I went to the NeXT extravaganza this morning at Davies Hall. It was
pretty interesting, both as an event and because of the machine they
announced.
Steve Jobs was, naturally, the star of the show. He began with a fairly
simplistic pitch about the ten year lifecycle of any computer architecture,
why it peaks at five years and how it then goes into a "glide slope"
into eventual decline. He claimed that the Mac will peak in 1989,
and that NeXT is defining the architecture for the 1990s, which should
peak in 1994-95. (He also said something about why NeXT should be able
to avoid the glide-slope effect, but it didn't make any sense to me.)
After reading the ad from this morning's WSJ, he talked about the
needs of the university market: Unix (esp good networking and true
multitasking), great user interface technology, 5 MIPS, at least 8
MB RAM, at least 100 MB disk, Display Postscript, 1 megapixel, sound,
open architecture, laser printing and a small, cool, quiet package.
Not too surprisingly, turns out to be a good description of what they
have built.
One of the main things they focused on was sufficient memory bandwidth
(around 35 MB/s) and the ability to parcel it out to concurrent demand
streams. In addition to the processor/cache and display/VRAM, they
have 12 DMA channels. This (and a lot of other stuff) is done using
a pair of big custom CMOS chips, reducing the total chip count of
the machine to 45. Memory is on SIMMs, with a minimum system of 8 MB
and a maximum of 16 MB (64 MB when 4Mb chips arrive). The standard
machine also includes a floating point coprocessor and a digital signal
processor, which was characterized as 10 MIPS (whatever that means).
The DSP is used for speech, music, image processing, encryption, FFTs,
etc. It also does most of the work of the 9600 baud modem and some
kind of FAX port. The sound output is CD format (2 channels x
16 bits x 44.1 KHz.) There is a built-in ethernet controller (and
thinwire transceiver, I assume). All of this comes on one medium size
board, which mounts vertically in the 12" cubical cabinet. There are
four slots total, so three are free for expansion. The backplane is
a modification of the NuBus, speeded up to 25 MHz (implemented using
another custom CMOS chip, which they plan to sell to 3rd parties for
$25). There are two slots on each side of the cube, and in the middle,
there is space for two full-height disk drives. The power supply is
in the bottom. The base configuration includes a 256 MB erasable optical
disk; the cartridge looks like a CD sealed in a slightly oversized
"jewel box" and sells for $50. There are optional 330 and 660 MB hard
drives that connect through a 4MB/s SCSI port. They cost $2000 and
$3000, respectively.
The gray-scale display is 1 M pixels x 2 planes. Connected to it are
the keyboard and two-button mouse. On the back of the display are
all the other connectors (stereo sound, microphone, headphones etc.)
It has exactly one cable coming out of it, which carries video,
key/mouse events, all sound channels, and power from the cube.
The above emphasizes some lessons they seem to have learned from the
Macintosh experience:
1) Closed systems just don't fly
2) Tiny displays are unacceptable
3) Your smallest configuration will haunt you forever
Regarding 1, they have paid a lot to keep the system open. Since
they use one big card and wanted all slots identical, they had to
make both the box and the power supply much bigger. Just what might
end up in slots 2-4 isn't clear, but judging from what they crammed
into slot 1, you could get an awful lot into that 12" cube!
Regarding 2, they had a cute demo, in which they simulated a 9" Mac
screen on theirs and then expanded out to full size. During this,
there was the interesting gesture of acknowledging that the Mac was
based on ideas pioneered at Xerox PARC. Not clear whether this gesture
should be seen as a tip of the hat to Xerox or a kick in the shins
to Apple.
Regarding 3, they seem to be willing to force the early customers
to spend more so that later in life, software developers won't feel
hobbled by the "least common denominator" effect (e.g. 128K Macs).
On the other hand, for what they force you to buy, they asking a pretty
low price. To university customers, the base machine costs $6500.
You can't get much Mac II for that kind of money...
Their laser printer is distinctly smaller than a Laserwriter. It's
based on a Canon engine and connects directly to the cube. It combines
the low cost of direct wire interconnect with full Postscript capability
(which is all done in the cube). The thing costs only $2000. It prints
at 400 dpi, which almost doubles the areal density and is claimed
to give clearly visible improvement. (I didn't see any output.) For
compatibility, it will print at 300 dpi, which Jobs referred to as
"draft mode". To use it as a network print server, you currently need
a cube with it to handle the Postscript, etc. Perhaps a bundled print
server configuration will come out later.
They showed a movie about their automated assembly line, which they
say produces the boards literally untouched by human hands. They had
snazzy looking video/laser scanners controlling robot arms for
pick-and-place, unattended soldering for both surface mount and
through-hole components, and so on. I don't know much about the state
of the art in this area, but the movie made it all look pretty
impressive.
The software is based on Mach, NFS and Display Postscript. They program
in Objective C, and provide an applications environment called NextStep.
This consists of their own window package, a pair of tools called
Interface Builder and Connect (similar to Luca's DialogEditor) and
a library of objects and interactors which can be plugged together
to build an application. (Of course, you would typically need to code
up some new objects of your own in Objective C). The window system
does a *very* effective job of using the grayscale and halftoning
to give an almost tactile 3-D feel to the windows. There are little
beveled edges and pretty icons everywhere that provide a very "warm"
feel to the whole thing. You can drag fully painted windows (not just
outlines) around the screen in real time. It also has pop-up/tear-off
menus, a nice icon "docking" facility, etc. The trash can has been
replaced by a black-hole icon.
Perhaps the biggest news about NextStep is that they have licensed
it to IBM. (This was rumored, of course, but then so was the idea
that the machine was made of magnesium, or that it had X-Windows in
ROM.) This is a clear bid to draw more application developers into
the pool. What it will really mean in the long run (wrt presentation
manager, etc) is hard to say.
Of course, availability of application software will ultimately
determine the fate of the machine and the company. They seem to see
Unix compatibility as important in initial sales, but claim that "once
you see NextStep applications, you'll never want to run old Unix
applications again". To increase the attractiveness of the new system,.
they are bundling a large amount of software in the base price:
Mach (incl NFS, and TCP/IP)
Display Postscript
NextStep (Window system, UI building tools)
Mathematica
Franz CommonLisp
Objective C
SyBase SQL Server database
Unix compatible mail program (Postcard-like)
WriteNow (basic word processor)
Music synthesis software
Digitized sound software
Digital Library (Merriam Webster dictionary/thesaurus, Oxford
Dictionary of Quotations, complete works of Shakespeare, etc.)
(and probably one or two other things I've forgotten...)
They demonstrated several applications, and all the software seemed
to perform well. Of course, they are undoubtedly still in tapdance-
through-the-minefields mode. They did *not* allow any hands-on usage
of the running machines displayed in the lobby.
To close the event, they had a Bach duet played by the NeXT machine
(on synthesized harpsicord) and a violinist from the SF Symphony. It
was a nice touch, very much in keeping with the tone of the morning,
which seemed distinctly off to one side from the nerds-to-businessmen
axis that Apple has traversed over the years.

| The long descriptions in the MACINTOSH and ASIMOV::MARKETING notes
file say that the "4 gray level shading is used effectively to make
displays almost three-dimensional." What little I've seen of this
machine on TV shows rendering that looks quite nice at a distance.
Given the visually pleasing display of the Macintosh, it would not
be surprising at all if the display looks good by design. Given
the hefty software in the Mac ROM, and the digital signal processor
in the Next machine, it would not be surprising at all if they do
stuff like dithering and other shading algorithms as standard.
BTW, the Thursday _Wall Street Journal_ has a nice summary article
on the machine, the company, and Jobs. Vaporware dept.: they're
not shipping until next June (?!).

1774.11 | NEXT is 2 bits/pixel monochrome | PRNSYS::LOMICKAJ | Jeff Lomicka | Mon Oct 17 1988 16:20 | 12 |
| Bear in mind that to many people, color is for toys, and real works
takes place on a nice, SHARPLY FOCUSED flicker-free monochrome tube.
This is, of course, the bottom line reason why I suffer with an Atari-ST
and TOS rather than enjoy the many benifits of the Amiga's OS.
To me, the NEXT sounds like GREAT home computer. The thing's got a 9600
baud modem (okay, it uses the DSP and software) included in the BASE PRICE.
BBoard systems will never be the same again.
(Of course, Next is TEN TIMES the cost of my Atari system.)

| I'm not sure if this is what they had in mind, but with 2 bits/pixel,
it becomes possible for a NEXT to do smooth animation in a window, by
writing pixels in the off-plane between animation frames, and hitting
the color map once during the next vertical retrace. Animation in a
window is not possible with fewer than two bitplanes.
I wonder if they have window-specific color maps?

| Excuse my pessimism, but I'm not really impressed with the NeXT
at all. I LIKE color graphics, and that's one of the reasons I
bought my Amiga. Granted, the NeXT comes with a lot of things built
into it, but at $6500, it couldn't POSSIBLY be aimed at college
students. And this is the DISCOUNT price? Yes, $6500 is a TERRIFIC
deal for what you get, which is a noticeable improvement on current
computers, but I know VERY few students who could even think about
afforded a computer like that. It would be a wonderful computer
for a group purchase, but I think it is going to end up just like
the MAC II at my University. A lot of Ahs, Oohs, and "Sorry, can't
afford it until after college" remarks. So, I don't see this monster,
as good as it may be, as being serious competition for the Amiga.
If I want that kind of ability, I'll go buy a VAX or something.

According to another long article on NeXT that's been making its way
around the net, NeXT is aimed at the higher education market, but not
necessarily at students. As you pointed out, they're too expensive
for students, so you'd expect to find them in shared-resource areas,
not in dorm rooms.
Also according to this article, NeXT's target is a $3000 workstation.

| Apart from the r/w CD-ROM (CD-RAM?) what's the big deal? As someone
said earlier the Amiga architecture was revolutionary when it appeared.
The Next architecture seems rather ordinary. I mean, what Jobs
has done is to graft existing technology together (albeit in a nice
way). I'm still waiting for someone to explain why this approach
is the next generation, and why it will avoid the 'glide-slope'
of approaching obsolescence.

Next - Come comments/info about its first machine
And some don't even consider it a breakthrough machine. "Frankly, I'm
disappointed," says William H. Gates, the founder of Microsoft Corp. "Back in
1981, we were truly excited by the Macintosh when Steve showed it to us
because when you put it side-by-side with another computer, it was unlike
anything anybody had seen before" because of its distinctive graphics. But
with regard to the Next computer, he says, "In the grand scope of things, most
of these features are truly trivial." Although Microsoft develops popular
programs for Apple and IBM personal computers, Mr. Gates says there's "no
way" he will have his programmers write software for the Next anytime soon.
"Steve is going to talk revolution in the computer business, but unfortunately
you'll find more similarities than differences between his machine and other
workstations," adds Mr. Joy of Sun Microsystems, probably Next's main
competitor. "And some of the differences that glitter now may well tarnish in
a while." Next's Japanese vendors, who sell the company everything from chips,
monitors and laser-printer engines to a pioneering removable optical-disk
storage device, have granted the company open terms of payment. Even though
Next has yet to ship a computer, Tandem Computer Inc. has virtually donated
much of the equipment that Next is using to set up an information-systems
department powerful enough for a company with broad-based channels of
distribution. consultants and other vendors say they grant Next deep
discounts - as much as 50% off - in return for the free publicity that
supplying the company generates. "The idea appears to be to seed the nerds and
enthusiasts and let them make the computer look good, much like hobbyists
transformed the original Apple II into a broadly popular machine," says David
Grady, who publishes the Grady Report, a newsletter on computers in education.
"Once it's established in the universities, they can take it into the
mainstream." Mr. Jobs is betting that the Next computer, which he contends is
much easier to program than personal computers or other workstations, will
make a big splash right away. According to John P. Crecine, one of three Next
directors and the president of the school of information at Georgia Institute
of Technology, the company hopes to ship between 25,000 and 30,000 computers
after deliveries to customers begin next year. (Next will ship some to
software developers late this year.) Assuming that Next charges the full
$6,500 prices, its revenue will approach $175 million if those sales targets
are met. Judging from the interest shown by university officials who have seen
the machine, Next won't have much trouble selling it initially. The crucial
operating-system software called MACH came from outside Next. So did many
features of the computer's slick look and feel. And so did much of the
applications software bundled with it, such as the mathematics program and
programming languages.
{The Wall Street Journal, 13-Oct-88, p. A1}
IBM - Licenses software from Next, Adobe Systems and Stepstone
IBM, as expected, said it has licensed some of the software inside the Next
machine. IBM hopes the Next software will make it easier to program and use
IBM technical workstations. That is a market in which IBM has lagged, but is
planning a big push to gain new ground. Like Apple's Macintosh, the Next
software lets a user execute complex commands by pointing to visual symbols on
a screen. IBM said it also licensed software by two other companies whose
programs are used in the Next system: Adobe Systems Inc. of Palo Alto, Calif.,
and closely held Stepstone Corp. of Sandy Hook, Conn.
{The Wall Street Journal, 13-Oct-88, p. A16}
Next - Software programmers embrace Next
"The Macintosh was a revolution, but software developers paid the price,"
Steve Jobs told 3,000 people at Davies Symphony Hall Wednesday. "It's a bear
to develop software for the Mac," said Jobs, who led the Macintosh development
team at Apple. Jobs touched a sympathetic cord when he addressed the
programmers in the audience, saying his new computer eliminates the most
time-consuming task facing Macintosh software developers: tailoring software
to the computer's sophisticated user interface. Software programmers won't
have the same problem with the Next computer since that step has been
eliminated. That revelation won applause from programmers. Jonathan Seybold,
president of Seybold Publications Inc., which publishes newsletters on desktop
publishing, said the computer's "ground-breaking" technology will dramatically
reduce the time it takes to develop new programs. "It could cut that time in
half, depending on the complexity of the program," he said. The technology,
called NextStep, won the endorsement of IBM, which plans to offer the software
with future computers. Esther Dyson, editor of Release 1.0, an industry
newsletter published in New York, said the IBM pact will motivate software
developers to write software for the Next machine. Adobe Systems Inc. has
already put its stamp on the new machine. Its Display Postscript software is
incorporated in every machine and allows the computer to display graphics and
text more accurately on the screen. Other companies have also embraced the
new machine. Frame Technology Corp., a 2-year-old San Jose, Calif., firm,
plans to introduce professional publishing software for the Next computer in
mid-1989. The Next computer includes a variety of software that comes
"bundled" with the machine, at no extra cost, including a computer language
known as Allegro Common Lisp, which is sold by Franz Inc., a young Berkeley,
Calif., firm. Another company that has software packaged with the Next
computer is Sybase Inc. of Emeryville. It is providing database software.
David Liddle, chairman of Metaphor Computer Systems, a Mountain View, Calif.,
company, and a pioneer in user interface technology, said Next's computer is
going to "catch the current software development community by surprise."

>Just WHAT is it about the NeXT interface that allows easier programming?
As far as I can tell, I believe Jobs is claiming the system is easier
to program because all of the software is "object oriented." The
interface to the system software is designed for Objective C, one of
the two object oriented variations of the C language (the other is
variation is C++).
Objective C is follows the dynamic binding philosophy of Smalltalk.
C++ has more static bindings, and generally runs faster. C++ is
probably the far more popular of the two languages.
By the way, Apple now uses object oriented programming to write all
of their stuff. Don't know why Next thinks its object oriented
programming is better than Apple's.

1774.21 | Interactive user interface editor | PRNSYS::LOMICKAJ | Jeff Lomicka | Wed Oct 19 1988 11:32 | 11 |
| The NEXT development environment includes a user interface editor,
similar in concept, I would imagine, to the resource editors available
for the Atari-ST that I've seen and used. For classes of applications
where the user interface is static, these tools will greatly speed the
time it takes to develop the user interface to an application, something
that, with all this fancy graphics and menus, can take a long time with
justy ordinary programming.
Of course, if you can get it for the Atari, it can't possibly be TOO
revolutionary.

So, all this amounts to is that Jobs is just boasting about integrating
several useful, but longstanding software and model packages into
his computer. That's fine. It's a nice "idea." (This kind of
thing has been done before) But I wish he wouldn't call it new
or revolutionary. I just can't see myself paying an extra $3000
for the extra stuff. I expected much more from Jobs.

I remember reading a comparison between the Amiga and Mac system
routines in BYTE a few years back. The author, who had programmed
both systems, praised the Amiga for it's wealth of built in tools.
Speaking as a non-programmer, I had difficulty relating to any of
this, but the author presented, in flow chart format, what was required
in each system to open a window and scroll some text. (I think
that was the example given; anyone remember?)
The gist was that it took a lot more work on the programmer's part
to make the Mac do things. What was essentially one or two steps
with the Amiga took a dozen or so different steps on the Mac.
As an occasional Mac user, I wonder about this, since the Mac simply
blows the Amiga away in neatness of it's interface. Apparently,
programmers put in a lot of sweat to make it happen.
I suspect that NeXT has provided a wealth of easy ways to program
the interface. I can't wait to see one work, but I guess I'll have
to.

That is true. The Mac's windowing system was designed for a 128k machine
with no possibility of adding memory (Apple originally believed that
adding more memory was a great evil). They designed their windowing system
to use as little memory as possible, and to force the application to
do all the work.
When you click on a Mac window, the application must pop the window
to the front, and redraw from scratch any parts of the window that
was previously hidden.
On an Amiga, all of that entire operation would be handled by the
system without the application ever finding out. The system save
a copy of any piece of a window that is obscured, and can restore
an obscured piece of a window by just doing a memory copy using the
blitter.

Part of the problem is that the Amiga provides painless compatibility with
older paradigms for the user interface. With the Amiga, you can open
a window as a file using the filesystem, and treat it as a
more or less VT100 compatible terminal. A lot of Amiga programs fall
down on the user interface because you can take a random program
for a character cell terminal and run it in a window with no changes.
With the Mac, you would suffer just as much writing a character
cell terminal program as a snazzy gadget loaded program. Since you
basically have to do a redesign anyway, you might as well do the
job right.
Writing a Mac-like program for the Amiga is easier that writing a
Mac-like program for the Mac. However, writing a Unix-like program
for the Amiga is easier that writing a Mac-like program for the
Amiga.

that could be the secret. I've seen some amazing stuff done on
computers I regard as brain dead because their OS didn't offer
functions to do reasonable things easily. It appears that
programmers are basically lazy --- if the OS will do most of the
work for you, why bother doing anything different. If you have
to write your own routines to twiddle the bits, why not make it
look better while you're doing that.
I remember reading an interview with the author of PAWN in a ST
magazine. The author complained about how hard it was to program
the Amiga version because the operating system didn't support
screens that dropped down from the top. It only had support for
pull up/down screens. Guess they had to do some programming instead
of just making OS calls :-)

Newsweek has a cover story on Steve Jobs introduction of the NeXT machine.
It also has some neat pictures of the beast.

| re .26 - Yep, and the really obnoxious thing about the cover article
is its assertion that Jobs has "put the fun back into computing".
What sort of network connection (if any) does this "revolutionary"
machine have built into it?

The NeXT machine has a thin-wire Ethernet.
Also the R/W Optical disk is NOT CD-ROM compatible. I was at
DECUS and DEXPO last week and saw the same drive on a UVAX.
DEC with the help of 3rd party vendors "has it now".
