**Qualcomm Buys Now Software** -- Qualcomm, the wireless
  communications company best known in the Macintosh world for
  Eudora, today announced its acquisition of Now Software, makers of
  Now Utilities and Now Up-to-Date. Now Software had seemingly been
  in a slump of late, claiming that it lacked the engineering
  resources to update Now Utilities for Mac OS 8, so the acquisition
  comes at a good time for them. The press release noted that
  "Qualcomm intends to support Now's flagship products," so we hope
  that means an update to Now Utilities, although a Qualcomm
  representative was unable to share any details with us. More
  interesting is what Qualcomm gets out of the deal since Now's
  products don't obviously fit the Eudora division's focus on email.
  Rumor has it that Now is working on a revolutionary technology
  along the lines of the Now Synchronize data synchronization
  software. Qualcomm must have been attracted by the thought of
  synchronizing email and schedules across multiple platforms,
  including Macs, PCs, Newtons, PalmPilots, and Qualcomm's cellular
  phones. Although Qualcomm plans to keep Now Software's Portland,
  Oregon office open, the Eudora division has reorganized in the
  wake of the acquisition. We will miss one of the layoff casualties
  - tester Gary Nash, who was a fixture at Mac trade shows and user
  group presentations and who helped anchor the Macintosh Eudora
  mailing list. [ACE]

**QuarkXPress 4.0 Released** -- More than two years after the last
  release of QuarkXPress, Quark is shipping version 4.0 of the
  popular desktop publishing application. QuarkXPress 4.0
  incorporates new features such as support for character-level
  style sheets, the ability to create objects with bezier curves on
  a point-by-point basis, and options for controlling clipping paths
  in images. In addition to a U.S. English version, Quark has also
  released QuarkXPress Passport 4.0, which incorporates Danish,
  Dutch, French, German, International English, Italian, Norwegian,
  Spanish, Swedish, and Swiss-German into one product. The U.S.
  English version costs $995, with a variety of pricing options for
  upgrading, depending on which version you currently own; the
  Passport version has a suggested retail of $1,595. A 16 MB demo is
  also available via FTP download. [JLC]

**BBEdit 4.5.1... and 4.5.1a** -- Last week, Bare Bones Software
  released an update to BBEdit, a widely used text, HTML, and
  programming editor. According to the press release, the new BBEdit
  4.5.1 supports HTML tags for style sheets, frames, scripts, and
  applets, plus provides enhanced HTML updating and validation.
  Other changes include welcome improvements to TableBuilder,
  enhancements to the Find Differences command, and support for
  longer search strings. Unfortunately, the rollout of BBEdit 4.5.1
  wasn't smooth: the original BBEdit 4.5.1 update had a small
  problem, so Bare Bones released two new updaters for BBEdit
  4.5.1a: a complete 2.3 MB "4.5.1 updater" (which, despite its
  confusing name, updates 4.5 to version 4.5.1a) and a smaller
  "4.5.1a" update only for people who installed the flawed 4.5.1.

**Eudora Internet Mail Server 2.0 Released** -- Qualcomm has
  released the final version of the $199 Eudora Internet Mail Server
  2.0 (EIMS), which provides significant enhancements over the
  still-available free EIMS 1.2. Important improvements include the
  capability to handle multiple local domains, prevent spammers from
  relaying through your mail server, administer the server remotely,
  connect intermittently, and make user information available via
  Ph. For $299, you can purchase EIMS 2.0 plus five licenses for
  Eudora Pro. EIMS 2.0 requires a 68030 Mac or higher running System
  7.1 or later with Open Transport 1.1.2 or later. A 60-day expiring
  demo version is also available as a 1.2 MB download. Overall,
  we've been impressed with EIMS 2.0 in our testing; however,
  Qualcomm's online purchases are available only in the U.S. and
  Canada right now and work through Software.net. Our one experience
  with Software.net's unlocking scheme and our subsequent
  interaction with customer service was terrible. Our advice: save
  all email relating to your order in case problems develop. [ACE]

**QuicKeys Revs for Mac OS 8** -- After installing Mac OS 8,
  QuicKeys users have encountered problems with installed contextual
  menu commands not appearing on menus and with the Close Window and
  Zoom Window Mousies failing. Although CE Software provided
  workarounds that helped with these issues to varying degrees, a
  fix is now at hand in the form of the QuicKeys 3.5.2r1 updater,
  which corrects these problems in QuicKeys 3.5.2. CE's download
  page links to the new updater and to software for updating 3.5 to
  3.5.2. [TJE]

**Connectix Updates Speed Doubler** -- Connectix has posted an
  English updater for Speed Doubler that takes the recently released
  Speed Doubler 8.0 to 8.0.1A (see our MailBIT in TidBITS-402_ for
  more Speed Doubler 8 information). If you downloaded but haven't
  used the 8.0.1 updater posted early last week, make sure you grab
  the most recent file, which corrects a problem with the updater
  itself. If you used the previous updater successfully, don't
  bother downloading 8.0.1A. The update to 8.0.1A fixes a number of
  bugs and a conflict with the StuffIt Browser in Aladdin's StuffIt
  Deluxe 4.5. Those upgrading to 8.0.1 should note that the Speed
  Doubler Updates page offers updaters for both Speed Doubler and
  Speed Copy. [JLC]

**Stairways Software Releases Greebles** -- In a departure from
  their focus on Mac Internet tools like Anarchie, NetPresenz, and
  Internet Config, Peter Lewis's Stairways Software has released
  their first game, called Greebles. Stemming from the two-
  dimensional maze and block-pushing genre of the arcade game Pengo,
  Greebles ups the ante with over a dozen types of blocks, numerous
  types of Greebles (the bad guys), both friendly and nasty computer
  players, and 100 built-in levels. As you'd expect from Peter
  Lewis, although you can play Greebles alone, it's also a multi-
  player game with up to four people playing on a single computer
  and up to nine computers connected over the Internet
  (unfortunately 33.6 Kbps modem connections don't provide
  sufficiently high throughput or sufficiently low latency - see
  Stuart Cheshire's Bandwidth and Latency articles in TidBITS-367_
  and TidBITS-368_). A Greebles Tracker Web page displays public
  Greebles games so you can join network games in progress. Greebles
  requires a 68040 or PowerPC-based Mac; System 7.0 or later; 3 MB
  of RAM; and a 640 by 480, 256 color-capable system. Network play
  requires Open Transport 1.1 or later and a TCP/IP network.
  Greebles is $15 shareware with multiple copy discounts available,
  and registered users can build their own levels.

Is Apple Thinking Different?
----------------------------
  by Adam C. Engst <ace@tidbits.com>

  At a press conference today, Apple interim CEO Steve Jobs
  announced a line of new Macs and Apple's new WebObjects-based
  Apple Store, which enables customers to purchase Macs and other
  Apple products online and to customize the configurations of the
  new G3 Macs.

  More interesting is what didn't happen at the press conference.
  Apple didn't merge with Oracle (though rumors of Oracle investing
  in Apple to help support Apple's network computer efforts make
  some sense), Apple didn't announce a partnership with Lucent, and
  Steve Jobs didn't accept the CEO position (or even the coveted
  title of Dictator for Life). None of the widely circulated rumors
  turned out to be true, as is so often the case, and life goes on.

  Apple should be both commended and condemned for their handling of
  this situation. On the one hand, by allowing the Oracle buyout
  rumors to persist (and one wonders if they might not have been
  intentional), Jobs managed to turn a fairly interesting
  announcement into a public relations coup. There's no way that
  Apple could otherwise have generated such interest for new
  machines and an online store, and for that Apple should be
  commended. However, I don't believe it's healthy for the Macintosh
  world to sustain such intensity surrounding Apple's possible moves
  and by encouraging that intensity without delivering (as Jobs did
  in part by telling BusinessWeek that their fairly accurate article
  last week was "way off"), Apple does its users a disservice. I'm
  seeing people burn out and cease to care what happens to Apple or
  the Macintosh, and Apple can't afford that right now.

<http://www.businessweek.com/1997/46/b3553159.htm>


**New Power Macs** -- The public rationale for the press
  conference was to announce Apple's latest Macs, all based on the
  new PowerPC 750 chip, more commonly known as the G3. In this
  issue, Tonya covers the specs of the new G3 machines in detail and
  Geoff looks in more detail at the G3 chip used in the new
  machines.

  These machines are unquestionably fast, and the prices aren't bad
  by any means, competing well with comparably configured machines
  from at least the Dells and Compaqs of the PC world, if not the
  less-expensive no-name vendors. Those are both positive facts for
  Apple in light of this year's decision to reduce Mac OS cloning
  efforts to far lower levels than they were prior to the Power
  Computing buyout we covered in TidBITS Updates and Motorola's
  exit from the Macintosh clone market, which we looked at in
  TidBITS-397_.

<http://db.tidbits.com/getbits.acgi?tbart=04138>
<http://db.tidbits.com/getbits.acgi?tbart=04119>


**If You Build It...** More interesting in many ways than the
  release of the new G3 Macs is the new Apple Store, which is well-
  designed and graphically attractive. Based on the WebObjects
  technology acquired with NeXT, the Apple Store is Apple's latest
  foray into direct sales (previous attempts, such as the Apple
  Club, have been half-hearted and poorly implemented). The Apple
  Store is available via the Web site below or via phone at 800/795-
  1000 (which reportedly goes to MicroWarehouse answering as Apple
  Computer). For those of you in other countries, it appears that
  the Apple Store currently caters only to U.S. customers. I imagine
  that will change in the future, but it will take Apple a while to
  address international shipping, currency, and support issues.

<http://store.apple.com/>

  The Apple Store appears to carry most of Apple's product line,
  including Macs, peripherals, Newtons, and software. For the most
  part, pricing is comparable to what you'd find at Apple resellers,
  although a Special Deals page lists some clearance items and
  refurbished Macs at cheap prices.

  The most interesting part of the Apple Store is that it enables
  you to customize purchases of the new G3 Power Macs. In the past,
  if you wanted to buy a Mac, you had a choice of several different
  configurations, but any additional customization was your (or your
  reseller's) problem. Now you can specify the various aspects of
  the G3 Power Macs, including:

* Processor speed
* RAM amount
* Hard disk size
* Removable storage
* Graphics support (VRAM size)
* Modem inclusion
* Monitor inclusion

  The Apple Store reminded me of Power Computing's Build Your Own
  Box Web pages. After you select a basic G3 Power Mac, the site
  presents you with pop-up menus from which you choose desired
  options. A button at the bottom recalculates the sub-total so you
  can see the damage caused by deciding you really need more RAM and
  a 20" monitor. After that, a Continue button encourages you to add
  peripherals to your order, then takes you to the checkout.

  We're curious to see how much of a difference direct sales make
  for Apple since setting up a direct sales channel - particularly
  one that allows customization - requires massive infrastructure
  changes within the company. It's ironic that the changes necessary
  for a direct sales channel are much more significant than the
  impact on most individual users, who will see the Apple Store as
  merely another way to buy a Mac. In the past, it hasn't been hard
  to find someone who will sell you a Mac, ranging from companies
  like TidBITS sponsor Small Dog Electronics up to the superstore
  chains. Will direct sales mean more sales, or merely the same
  number of sales through a different channel? Apple probably stands
  to make more money on direct sales by cutting out the middleman,
  though some of that added profit will disappear into the effort of
  building and customizing the machines.


**But Do They Think Different?** One of today's Apple press
  releases says "Apple Computer today showed it takes seriously the
  "Think Different" message in its ads. The Company announced
  dramatic changes in the way it designs, builds, and sells its
  computers." I'm willing to concede that the Apple Store and
  providing customers the opportunity to customize their Macs are
  radically different ways of building and selling computers, at
  least for Apple, if not others in the industry. And, the G3 Macs
  seem nicely designed, if not stunningly designed.

<http://product.info.apple.com/pr/press.releases/1998/q1/
971110.pr.rel.direction.html>

  However, these are engineering and business details. Apple has
  released innovative machines in the past, and we've certainly seen
  numerous business changes over the seven and a half years we've
  watched Apple in TidBITS. What remains to be seen is if Jobs has
  managed to make the company _think_ differently. The visionaries
  and leaders portrayed in Apple's ads weren't the sort of people
  who changed a distribution channel or released incrementally
  better products - they thought and acted in ways previously
  unimaginable. Apple was once a company that did "think different"
  - if nothing else, Apple engineers created a system to which
  people could relate and with which they could identify. The
  Macintosh affected our lives, but Apple proclaiming "Think
  Different" from the electronic rooftops does little for me. The
  question remains: can Apple "think different" and transcend the
  limitations of large corporate culture to touch our lives once
  again?


Three New Macs and a PowerBook
------------------------------
  by Tonya Engst <tonya@tidbits.com>

  As Adam noted earlier in this issue, Apple has unveiled the Power
  Macintosh G3 series and the PowerBook G3. These new machines all
  sport the new PowerPC 750 chip, commonly known as the G3 (see
  Geoff's detailed coverage of the G3 and backside cache in the next
  article). Apple also announced the Multiple Scan Display 720, a
  new 16-inch monitor.


**Three New Macs** -- The G3, combined with a 512K backside cache
  and 66 MHz system bus, makes these new Mac run quickly, and
  they've performed well in published performance tests. They each
  come with 2 MB video RAM, three PCI slots for add-on boards, a 24x
  internal CD-ROM, and 10Base-T Ethernet. Also, these are among the
  first Macs to use SDRAM (Synchronous Dynamic RAM). Unlike regular
  DRAM, SDRAM doesn't use its own timing system; instead, it
  operates in synchrony with the computer's CPU. By synching up with
  the CPU, the SDRAM stays on schedule with the CPU and other
  components, thus avoiding slowdowns that would otherwise arise due
  to conflicting schedules.

<http://www.apple.com/powermac/g3/>
<http://www.macworld.com/pages/articlelinks/15.01.g3.speed.html>

  The high-end model - a mini-tower form factor -  runs at 266 MHz;
  contains a 6 GB hard disk and a Zip drive; and lists for $3,000.
  The list price drops to $2,400 if you settle for a desktop form
  factor and a 4 GB hard disk, and - at the low end - there's a 233
  MHz desktop model with a 4 GB hard disk but no Zip drive for
  $2,000. And of course, if you purchase these machines through the
  new Apple Store, you can customize the configurations to meet your
  needs.

  Initially, I was disappointed with the G3 series because the
  models are dull when contrasted with the sexy features in Apple's
  Twentieth Anniversary Mac (see my article about that machine in
  TidBITS-387_). Also, their relatively slow 5 MB/sec SCSI buses
  seemed an odd choice for such fast machines. Regular users won't
  care, but those doing high-end video, for instance, will.

<http://db.tidbits.com/getbits.acgi?tbart=02216>

  Although I'd still like to see Apple release truly exciting Macs,
  my initial disappointment has been smoothed over the reasonable
  pricing, and the fact that Apple appears to be abandoning its
  confusing model-numbering scheme. It's easy to remember that a
  "Power Macintosh G3" contains a G3 chip.

  In addition, these are the first Macs from Apple where each model
  contains the same logic board; custom components, including the G3
  chip and the backside cache, live on a daughter card (or
  "personality card") that can be popped into the machine as it's
  assembled. Although this isn't a new idea, it is new to Apple and
  should help them quickly fill orders for particular
  configurations.


**And a PowerBook** -- The new PowerBook G3, formerly code-named
  Kanga, runs at 250 MHz, and like its G3-based Power Mac brethren,
  comes with a 512K backside cache (running at 100 MHz, twice the
  speed of the system bus), and 32 MB EDO (Extended Data Out) RAM.

  The machine uses the same form factor as the PowerBook 3400 and
  also shares the 3400's four-speaker sound system, 33.6 Kbps
  modem/Ethernet card, and 12.1-inch TFT (thin-film transistor),
  18-bit, 800 by 600, active-matrix color display. With its 2 MB
  video RAM, the PowerBook can drive an external monitor in 24-bit
  color at 832 by 624 pixels or 16-bit color at 1,024 by 768 pixels.
  Other specifications include a PC Card slot, lithium ion battery,
  and a bay that accepts interchangeable floppy disk and 20x CD-ROM
  modules. All these features fit in a 7.7 pound package that costs
  a whopping $5,699.

  Who should buy this PowerBook? Those who need the speed and power
  now, and can't wait for prices to go down. Apple is targeting the
  PowerBook G3 at design professionals who want to create and show
  sophisticated images and animations on a single computer.

<http://powerbook.apple.com/web/show.qry?id=prod_g3>


**What's Next from Apple?** I've heard rumors of a Power Express
  line of high-performance Macs, due for release in early 1998 with
  83 MHz buses. There's also talk of a G3-powered PowerBook, code-
  named Wall Street, which, from what I've heard, should offer a 350
  MHz G3 and sport an optional DVD drive.


Caching Your Chips
------------------
  by Geoff Duncan <geoff@tidbits.com>

  Beginning in TidBITS-334_, we published a series of articles
  explaining the technical guts of a PowerPC-based Mac. We examined
  differences between PowerPC 601, 603, and 604 processors; Level 1
  and Level 2 processor caches, the importance of the system bus,
  the 68K emulator, and other items.

<http://db.tidbits.com/getbits.acgi?tbser=1001>

  Since then, the PowerPC world has changed. What is the PowerPC
  750, and how is it different than the 603e and 604e chips in other
  Macs? Why is Apple touting the 750 so heavily? What's a backside
  cache? This article will answer those questions - and maybe a few
  more.


**PowerPC 750** -- The newest member of the PowerPC processor
  family is the PowerPC 750, codenamed G3 by Motorola and Arthur by
  IBM. Like the 601, 603, and 604 series of processors, the PowerPC
  750 is a 32-bit RISC processor that's software compatible with the
  rest of the PowerPC line - meaning that the PowerPC 750 should
  have virtually flawless compatibility with all PowerPC-based
  Macintosh software.

  The PowerPC 750 provides incremental improvements over previous
  PowerPC chips. It has larger data and instruction caches (32K
  each) and is optimized for integer operations, which makes it more
  spritely at common computing tasks. (The potential downside is
  that the PowerPC 750 isn't as fast at floating point math as the
  earlier 604e.) The PowerPC 750 can run from two to eight times
  faster than a computer's clock, so (in theory) PowerPC processor
  upgrade cards running as fast as 528 MHz could be designed for
  Apple's just-introduced G3 Macs.

  In addition, branch prediction in the PowerPC 750 has been
  improved, providing another across-the-board performance increase.
  In general terms, branch prediction is a low-level technique that
  processors use when code can do different things depending on the
  value of particular data. When the processor reaches a point where
  it must wait to learn a value in order to continue executing code,
  it makes a reasonable guess at what the value is likely to be and
  continues processing, instead of waiting simply around for an
  answer from RAM or an even slower subsystem. When the appropriate
  data is returned from memory or a subsystem, the processor looks
  at it and makes a decision. If the processor "predicted" the right
  path, it's already well on its way to finishing the task (or even
  done); otherwise, if the prediction was inaccurate, the processor
  starts again from the decision point, which is what it would have
  had to do if it hadn't guessed in the first place. Earlier PowerPC
  processors also do branch prediction; the PowerPC 750 improves on
  their model by making cached instructions immediately available
  once a path is resolved, rather than loading the cached
  instructions separately.

  Finally - and perhaps most interestingly - the PowerPC 750 is the
  first PowerPC chip designed for the Mac OS. This means the chip
  recognizes and efficiently handles types of byte sequences
  produced by (reportedly) Apple's and Metrowerks' compilers. All
  other things being equal (which they aren't; see above) a PowerPC
  750 is better at running typical Macintosh software than a PowerPC
  604e at the same speed.


**Watts the Deal?** Most Macs available today use either the 603e
  or 604e processor. The 604e was meant to be a high-performance
  chip for workstations, while the 603e was designed as a low-power,
  higher-speed version of the original PowerPC 601. That's why
  you've never seen a 604 processor in a PowerBook: they're too hot
  and they consume too much power.

  However, unlike the PowerPC 604 series, the PowerPC 750 offers
  high performance _and_ low power consumption, using just five
  watts of power at 250 MHz. In comparison, the PowerPC 604e
  consumes nearly 20 watts at 200 MHz. Portable machines using the
  750 can (in theory) rival the performance of desktop workstations.
  The PowerPC 750 features four power-saving modes which kick in
  automatically when functional units of the processor are idle,
  reducing power consumption and heat dissipation without impacting
  performance. The PowerPC 750 also includes a thermal assist unit
  which enables manufacturers to interrupt or slow down processing
  in response to temperature increases.


**Exposing Your Backside** -- So what's with the "backside" caches
  always mentioned in relation to PowerPC 750 systems? Well, a
  backside cache is just a faster version of a Level 2 cache.

  Level 2 caches are comparatively small units of high speed memory
  (256K to 1 MB) where PowerPC processors stash frequently used
  instructions and bits of data. Remember that in comparison to
  almost everything else on a PowerPC-based Macintosh, the processor
  itself is quite fast. That means it spends much of its time
  waiting for other systems, like RAM, video, networks, and disk
  drives. A fast Level 2 cache makes it so the processor can rapidly
  access frequently needed items and thus spend less time twiddling
  its thumbs, waiting for slower systems to respond. Increasing the
  amount of Level 2 cache in a PowerPC-based Mac is one of the
  cheapest and most effective ways to enhance performance.

  The problem with Level 2 caches on earlier PowerPC- based Macs is
  that the processor accesses the Level 2 cache by crossing the
  system bus, which acts like a traffic cop for almost every
  subsystem on the computer. On PCI-based machines, the system bus
  runs at a comparatively slow 33 to 50 MHz; Apple's new G3 desktop
  Macs use a 66 MHz system bus.

  The PowerPC 750, however, offers a built-in controller for Level 2
  cache on a separate, private bus, so the processor need not touch
  the system bus to use the Level 2 cache. This separate bus can run
  anywhere from one-third the speed to the full speed of the PowerPC
  750, so it's almost always faster than the main system bus. The
  bus handling the backside cache for Apple's G3 Power Macs runs at
  half the speed of the PowerPC processor, although some third-party
  PowerPC 750 processor upgrade cards run at the same clock speed as
  the PowerPC chip.

  Why not make the main system bus faster, rather than having a
  separate bus for Level 2 cache? In theory, that would be great:
  we'd all love for our system buses to run at 250 or 300 MHz. In
  reality, it's much harder and more expensive to engineer a system
  bus (and its requisite controllers for RAM, disks, networking, and
  other systems) to run that fast than it is to make a high-speed
  bus that does just one thing. However, increasing the speed of the
  system bus always improves performance, and you can expect to see
  83 MHz system buses from Apple in future models.


**More Info** -- Motorola has good technical information about the
  PowerPC at the first URL below (although, unfortunately, mostly in
  PDF format). In addition Apple has posted a succinct overview of
  the PowerPC architecture (including the G4 processors expected in
  1999), and IBM also has made some information available.
