Well, I just got back from the NeXT introduction at Davies Symphony Hall
in San Francisco and thought I would update the net on what Steve Jobs
announced about the NeXT computer.

The machine is based on the Motorola 68030 with a 68882 floating point
chip as well as a 56001 DSP chip, all running at 25 MHz. It will support
up to 16 MB of RAM with 1 Mbit chips, maybe 64 MB with 4 Mbit chips (they
haven't tried this yet). Mass storage is on a 256 MB removable erasable
optical disk! Jobs said that the removable media goes for ~$50. The display
is a gray-scale mega-pixel display (no exact sizes given). There was no
mention of color. Everything is displayed with Display PostScript, developed
jointly by NeXT and Adobe. This apparently runs with a proprietary window
system. There was no mention of X Windows. Also standard are audio input
and output, ethernet, and SCSI. Jobs said that with the standard sound
capabilities, all that is needed for a 9600 bps modem is some software
and a phone connection.

The entire CPU board consists of 45 chips as compared to 100+ for a fast
PC and 300+ for a typical workstation. Everything has been crammed onto
a 12 inch square board through the use of very dense surface mounted
devices, and a few large custom CMOS chips. Two of these chips implement
what Jobs called a "mainframe on two chips". These basically provide fast
I/O processors for all I/O systems including the optical disk, SCSI,
ethernet, sound processors (I assume the DSP and A/D-D/A converters) and
the NuBus. The NuBus is run at 25 MHz (Jobs compared it to a 10 MHz NuBus,
is this what the Mac II uses?). The SCSI interface was reported to have
a 4 MB/sec. transfer rate. There are 12 I/O processors total.

The CPU box has 4 slots, 1 is used by the CPU board, the others were empty.
The box itself is a black cube a foot on a side. The display, keyboard and
two-button mouse are also black. The display has an integral adjustable
height and tilt stand. The display is connected to the CPU box with a single
3 meter cable which transmits the 100 MHz video, power, sound, keyboard
and mouse data. The back of the display has connectors for the keyboard and
mouse, along with a speaker, microphone and headphone jacks and gold-plated
RCA stereo jacks.

The sound capabilities of the system were impressive, being able to record
and playback high-quality sound. Using the DSP chip some very realistic
sounding music was generated on the fly in real-time.

The box, display, and everything else looked very modern and high-tech -
all black.

The operating system is based on MACH with NFS support. On top of this is
Display PostScript. Above this is what NeXT is calling NextStep. This
consists of their window server, interface builder, application builder
and workspace. This is what was licensed by IBM. On top of this are the
applications.

When you login, you get a browser several icons, and a menu on the screen.
The browser lets you move quickly from directory to directory, and to run
applications or open icon based directory windows. The root menu is always
on the screen, always on top, and may be positioned anywhere on the screen
(and even off the screen). The menus cascade, and the submenus may be torn
off and left on the screen. Along the right edge is what I think Jobs called
the icon dock. It is a set of icons for commonly used applications which are
kept on the left edge, and are always on top. If you need the screen space,
this column of icons may be slid down off the screen, leaving only the NeXT
icon showing. Icons may be freely moved in and out of the dock so you can
keep what icons you use a lot there.

Jobs said that the new environment should cut the time used in coding the
user interface of a program from 90% to 10% of the total coding time. With
the application builder Jobs said it would go to zero. The environment is
object oriented, I believe based on Objective-C. You can modify existing
stuff with subclassing and inherit much of the base application. The
application builder lets you build an application just by placing buttons,
sliders, and any other graphic objects into a window, and then attaching
the the input and output objects to object messages.

Software that comes bundled with the system include MACH, Display
PostScript, NextStep, the sound and music tools, the digital library,
WriteNow, Mail, Mathematica, Sybase and Franz Lisp.

The digital library consists of Webster's 9th Collegiate Dictionary,
Webster's Collegiate Thesaurus, the Oxford Dictionary of Quotations
and the Complete Works of William Shakespeare on-line. There is a built
in spell program and dictionary/thesaurus lookup application. A word can
be selected in any window and looked up. The dictionary even includes
the pictures.

WriteNow is a word processing system, Mail is arpanet compatible mail,
including the capability to send speech, Mathematica is for (obviously)
mathematical problems and such. Sybase is a sequel database server.

A PostScript laser printer was also announced the can run at either
400 dpi or in 300 dpi "draft" mode. The printer is markedly smaller
(shorter) that most laser printers. No mention was given of speed.

Several demos were run with rotating molecules, smooth scrolling text,
voice storage and playback, speech waveforms and FFTs, etc. Everything
ran well, and ran fast.

Jobs announced the following prices (apparently education prices):

	NeXT computer:           $6500
	NeXT PostScript Printer: $2000
	330 MB winchester disk:  $2000
	660 MB winchester disk:  $4000

Jobs said that machines will start shipping in early November '88,
the 0.8 pre-release of the software for developers will be available
in Q4 '88, the 0.9 pre-release for developers and aggressive users in
Q1 '89, with the 1.0 release for general consumption in Q2 '89.

All in all, the machine looked good and fast, although I wonder about
the fact that several desirable things were not mentioned, i.e., color
monitors, X-Windows, some kind of floppy drive for software distribution,
etc. I imagine a typical SCSI tape drive could be used for archival
storage.

I'm sure I must have left something out, but I'm sure someone will fill
in the gaps and correct any mistakes I made (sometimes it was hard to
hear from the nosebleed seats in the back row of the top balcony).

software developer that got invited to the announcement.
