- Oops. A couple of people wrote in to correct our mistake about the
- type of tape backup cartridge available for the Apple Tape Backup
- 40SC. Mark accidentally wrote that it takes DC600 tapes, when in
- fact it uses the DC2000 size instead. Sorry about that.

- Discount Prices
- ---------------
- Last week we threw in a table of suggested retail prices for a
- number of Macintosh models mostly because we had it on hand and
- thought it might be interesting to read and to refer to in the
- future. Charlie Mingo promptly sent us a table of published
- discount prices from various vendors listed in 15-Sep-92 issue of
- the New York Times, and we added in a couple from the 20-Sep-92
- Seattle Times. The different vendors account in part for strange
- differences in prices, but one way or another, we think you'll
- find this table more interesting. Please note that we are not
- pushing any specific vendors here, so you'll have to find a dealer
- yourself, and that dealer may not have the volume of a New York
- City or Seattle store to match these prices. But next time you're
- in the city...

- SuperMac and Manager7
- ---------------------
- A friend writes to tell us that SuperMac has arranged with Casa
- Blanca Works to release a special subset of their Drive7 software
- which only works on SuperMac hard drives, including the LaserFrame
- rewritable optical drive. The package is called Manager7 and users
- of SuperMac drives can get it for free.
-
- Manager7 updates most SuperMac hard drives and LaserFrame optical
- drives and formats almost all SuperMac hard drives, including
- DataFrames. The main drive not supported is the 20 MB Iomega
- Bernoulli portion of the DataFrame 60+B drive (you'll have to talk
- to Iomega if you've got one of those). Manager7 supposedly
- completely solves all the System 7 and Quadra problems found in
- Manager 4.2.
-
- You can download Manager7 from CompuServe, America Online, GEnie,
- AppleLink, and SuperMac's BBS, and for a $10 disk and shipping
- charge Casa Blanca Works or DriveSavers will ship it to you. In
- addition, owners of SuperMac drives can purchase the full package,
- Drive7 2.3, for half price, or $39.97, until 01-Feb-93.

- HyperCard Player Bundled with Macs
- ----------------------------------
- by Mark H. Anbinder, Contributing Editor
-
- Apple has announced that, as of 14-Sep-92, it has begun shipping
- new Macintosh computers with a run-time "HyperCard 2.1 Player"
- program in place of the more-functional HyperCard 2.1 software
- that has shipped with all Macs since last fall. The company's
- license from Claris to distribute HyperCard itself expires on
- 30-Sep-92.
-
- The Performa line, available through consumer retail outlets
- rather than dealers, is the first group of Macintosh computers to
- include the new HyperCard 2.1 Player software, which includes the
- player application, a special Home stack, and a Read Me file but
- no sample stacks or a manual. By the end of the month, Apple
- expects all computers in their inventory to include the new
- software in place of the full HyperCard version.
-
- For Macintosh models of which a floppy-only configuration is
- available, such as the Quadra family and the IIci, a HyperCard 2.1
- Player floppy disk will come with the system. Other CPUs will only
- include the software pre-installed on the internal hard drive.
-
- New Macintosh purchasers who want the complete HyperCard package
- in order to develop their own stacks will still be able to
- purchase Claris's HyperCard Development Kit, which retails for
- $199. Most Apple dealers sell this kit.
-
- Apple's research has shown that most people who use the free copy
- of HyperCard that came with their Macs simply use stacks that
- other programmers have designed, and Apple feels that few people
- will be affected by this change. While we feel that this may limit
- the number and variety of nifty stacks generated by "average Mac
- users," it does make sense not to force all Macintosh purchasers
- to pay for something that only a few use. (The same logic applied
- to Apple's decision to introduce the Macintosh IIsi with a single
- expansion slot, after they learned that most users of three-slot
- and six-slot machines only filled one anyway.) If Apple did not
- include the new HyperCard Player with the machines, we would
- complain vociferously... but this seems to be a good compromise.

- Portable Batteries Live On
- --------------------------
- Ed Mechem writes, "Good news for Mac Portable users. There is a
- third party battery replacement available from Shadow
- Technologies, and it provides twice the life of the original
- battery. I've used my (non-backlit) Portable with the hard drive
- running continuously for close to five hours, and the battery
- still had some juice in it. My Portable has 9 MB of RAM (mostly
- low-power pseudo-static), and a 120 MB Connor 30100 hard drive.
- Shadow Technologies also makes PowerBook and Portable RAM
- (including the only user-expandable card that can hold up to 8 MB,
- to my knowledge)."
-
- [I talked to Shadow Technologies about this, and the battery,
- which retails for $149, should start shipping in quantity soon.
- They estimate that it will provide two and half times the battery
- life of Apple's batteries due to different lead-acid cells. In
- addition, you can disconnect the battery for storage by simply
- removing it, flipping it 180 degrees, and reinserting it, rather
- than removing it or putting mylar between the contacts. Shadow
- Technologies has other products for the Portable and the
- PowerBooks in the works, including a $550 backlighting upgrade for
- the Portable and some other possibilities they didn't want to
- announce yet. -Adam]

- As Does the StyleWriter
- -----------------------
- by Mark H. Anbinder & Adam C. Engst
-
- A nasty rumor has surfaced recently on the nets, claiming that
- Apple has either discontinued the StyleWriter entirely or has made
- it exclusively available to the consumer electronics channel. The
- rumor is not entirely unfounded, because Apple has removed the
- StyleWriter from some price lists temporarily not because it is
- unpopular, but because it is too popular. Rest assured that the
- StyleWriter is here to stay, although it may take a while to get
- one.
-
- The StyleWriter is in short supply right now because Apple
- severely underestimated the demand, and has run into a long lead
- time to produce more. Apple purchases the inkjet engine for the
- StyleWriter (manufactured by Canon) months in advance, and Canon
- cannot currently deliver more units than Apple has ordered.
-
- As a result, Apple has taken the StyleWriter off the price lists
- for some of its channels, notably government, K-12, and one of two
- higher education channels. This is because, for these channels,
- Apple must legally deliver ordered products within a certain
- length of time, and since they can not be sure of being able to do
- that, they do not want further orders placed.
-
- Sears and other consumer retail outlets selling the Performa line
- will have trouble getting StyleWriters for a while since Apple
- estimates two months or so before the shortage clears up. So don't
- worry if you have your heart set on a StyleWriter, but if you're
- not picky, you might consider the comparable, though slightly more
- expensive HP DeskWriter.
-
-
- 8*24 GC Video Card Refund Program
- ---------------------------------
- My apologies for losing this in my article database. On 15-May-92,
- Apple announced that they had identified a software bug in the 7.0
- version of the GC Control Panel that ships with the 8*24 GC Video
- Card. Despite the fact that the video card provides accelerated
- graphics, it has to run with the 68040 caches disabled, a major
- pain for Quadra users. If you bought an 8*24 GC card for use with
- a Quadra or a VRAM Expansion Kit for your Quadra's 8*24 GC card,
- you can return the item for a cash refund from Apple through
- 30-Sep-92.
-
- You don't have much time, but if you have a Federal Express
- number, Apple can FedEx you the forms, and you can FedEx
- everything back to them. They must receive everything by 30-Sep-
- 92, which is why you must act fast. I'll bet Federal Express hates
- it when people use their name as a verb, just as Xerox hates it.
-
- Contact Apple's fulfillment house at the number below between 8:00
- AM and 5:00 PM Mountain Standard Time to request an 8*24 GC Video
- Card Refund Program Return Form. That form includes the
- instructions you'll need as well as packaging materials to return
- your card. You then pack up your card in their packaging materials
- (the offer is void if you use other packaging) along with copies
- of your invoices for your 8*24 GC Video Card and your Quadra (with
- the serial number clearly listed), the invoice for the VRAM
- Expansion Kit if you bought that, and the completed Return Form.
- Remember, time is of the essence!

- PowerBook 100 Rework
- --------------------
- by Mark H. Anbinder, Contributing Editor
-
- Last Wednesday, Apple requested that owners of some early
- Macintosh PowerBook 100 computers return the units to the company
- for a minor modification to the logic board. The company says that
- the modification, to be made on some 60,000 PowerBook 100s,
- eliminates the possibility of a safety problem occurring with
- these machines.
-
- The problem, of which only three instances have been reported,
- involves an electrical short circuit that results in the melting
- of a small hole in the bottom of the system's outer case. Apple
- will make the modification (clipping the relevant component leads)
- at no cost (save the brief absence of the PowerBook. Apple
- believes that the problem occurs when a component lead contacts
- the metallic liner inside the bottom case.
-
- Apple stressed that this problem is unlikely to occur, and that,
- even if it does, the case is made of a high-grade, flame-retardant
- plastic composite, but that, in the interest of maintaining a high
- level of safety and quality standards, they are taking this
- proactive step to insure that all of the PowerBooks that have been
- sold are safe.
-
- Apple indicated that only a certain range of PowerBook 100s are
- affected, and that the 140, 145, and 170 models are unaffected by
- this problem. Only PowerBook 100s with serial numbers below
- SQ211xxxxxx or below SS216xxxxxx are affected. (The PowerBook
- 100's serial number appears on the underside of the computer on a
- narrow white sticker.) Currently shipping units (including most of
- the PowerBooks selling under $1000 at the Price Club and some
- dealers) do not have this problem, but users should check their
- serial number in case the computer they have just purchased was
- sitting on a shelf for a while.
-
- PowerBook owners within the United States whose computers fall
- within the affected serial number ranges should call Apple's
- dedicated PowerBook 100 Safety Helpline at 800/572-1731 to arrange
- for the modification. (PowerBook owners who have returned their
- registration cards will be contacted if their machines are
- affected. Always wondered why you filled those out, didn't you?)
- After confirming that the PowerBook in question requires
- modification, Apple will arrange for an overnight shipping service
- to pick up the PowerBook and bring it to a special repair center.
- The unit will then be modified and sent back via overnight
- service. Apple's plan is that this procedure will take no more
- than three business days for most owners. Early reports indicate
- that the procedure is painless.
-
- Apple subsidiaries in the European and Pacific regions will
- release information to customers in those areas to explain how
- those customers should proceed.
-
- Asked whether PowerBook owners could perform this modification
- themselves to avoid being without the PowerBook even for a few
- days, Apple replied that this was not an option; they would be
- unable to guarantee the consistency or quality of the modification
- if customers performed it themselves, even though it is "a simple
- procedure when performed by trained professionals in a controlled
- environment." A few dealers have recently become authorized
- PowerBook repair centers, but Apple does not allow them to perform
- this modification for their customers. Our experience has been
- that PowerBook modifications are inappropriate for end users to
- perform; the PowerBook is too sensitive, and some of its
- components too fragile for even some technically-oriented users to
- work on. (See TidBITS#90 "Quadra Quirks" for a warning about
- opening PowerBooks.)
-
- Based on Apple's descriptions of the problem and modification, it
- seems that most PowerBooks will never experience this... but since
- the repair is free, if your PowerBook falls within the affected
- serial number range, backup your hard drive and let Apple perform
- this repair.

- System 7.1 & the Golden Eggs
- ----------------------------
- Given the lead time necessary for mastering disks, it's not too
- surprising that System 7.1 has recently gone golden master. We
- talked about some of the features it will make available to users
- in TidBITS#137 and #138, although not all of them will make it
- into the initial release on October 19th with the new machines
- that require System 7.1. Can you say "Hardware drives software."?
-
- That's the good news. The bad news, to judge from some net
- discussions and general rumors, is that Apple will not make System
- 7.1 available to copy freely, which implies that Apple will only
- bundle it with new machines and sell it through its growing
- software distribution network. We've heard mixed reports about
- this, so it's always possible that Apple will recant and allow
- user groups and bulletin boards to distribute the system software
- for free again, as they did with System 7.0, but frankly, at this
- point it doesn't look likely.
-
- Most people will initially react poorly to this news, not
- surprisingly. After all, Apple has always distributed system
- software for free so they could be sure that all users at least
- had access to the latest and least buggy software. At the same
- time, Apple would cease to support older versions of the system
- software, so when Apple moved from System 4.2 up to System 6.0.2,
- they pretty much started ignoring 4.2. That stopped with System
- 7.0 when Apple said it would continue to support System 6.0.x
- (although all we've seen was the addition of new System 7.0-
- compatible printer drivers to bring System 6.0.7 up to 6.0.8). If
- they continue along this path of supporting older versions of the
- system software, the Macintosh market will become significantly
- more confusing and fragmented, what with System 6.0.8 running on
- older 1 MB machines, 7.0 on a large percentage of the newer
- machines, 7.0.1 on a number as well (and let's not forget Tune-Up
- 1.1.1!), and now System 7.1 running on power user machines (i.e.,
- the people who will pay for the upgrade) and all new CPUs other
- than the Performa 200 and 400, which will still use System 7.0.1P.
-
- The decision not to make System 7.1 freely available will further
- dilute the customer base using any one version of the system
- software, which will in turn discourage third party developers
- from taking advantage of system-specific features. Even if the
- third party vendors do exploit new system software features, they
- will still have to increase the size and complexity of their
- programs by ensuring that those programs work with other system
- software versions. That will slow the time to market and will
- require more work providing technical support ("Let me see, sir.
- You're running System 6.0.3 with Tune-Up 1.1 and the System 7.1
- printer drivers and Microsoft Word 5.1 prints messages from the
- devil in your headers and footers? Have you checked for INIT
- conflicts? Yes? Then I'm afraid you'll have to shoot your hard
- disk.")
-
- Pretty bleak, no? On the positive side, Apple stands to make a lot
- of money from this policy, and as much Apple seems to make a heck
- of a lot more money than most of us, we all do have a stake in
- keeping Apple healthy. Microsoft earns a ton of money from sales
- of DOS 5.0 and Windows 3.1, not to mention all the bundling deals,
- and I'm sure that Apple got a bit jealous. Also, keep in mind that
- hardware is a cutthroat business with ever-sinking profit margins
- and plenty of sharks circling. Although it certainly takes time to
- create and support software, it has very low material costs and
- high profit margins. A hefty package like Excel, for instance,
- probably costs barely $20 to produce, but still sells for about
- $300 discount. To compare, the Quadra 700 with 4 MB of RAM that
- Apple sells at discount for $3300 would have to cost $220 to
- manufacture. I don't know material costs for most machines, but
- I'm willing to bet that a Quadra 700 costs a bit more than $220 to
- make. My point? Merely that as Apple makes more money from high-
- volume, low-priced software, they will be able to lower prices on
- lower-volume, higher-priced hardware to better compete with the
- PC-clone hardware sharks. As much as I dislike higher prices, I'd
- prefer that Apple prospered, lowering the hardware prices that are
- the entry fee into the Macintosh game.
-
-
- The details
- It looks as though Apple will have three different upgrades for
- System 7.1, one which will include only System 7.1 for $39 ($20
- street), one which will also include QuickTime 1.5 and WorldScript
- for $99 ($49 street), and the CD-ROM multiple user version for
- large sites. Despite the complaining above, most people can
- probably afford $20 for the seven disks or so that will comprise
- the upgrade. I'll bet that most QuickTime-based products will
- include QuickTime 1.5, and unless you use multiple languages,
- there's not much reason for WorldScript.
-
- What I'm getting at is that many people may not want to upgrade
- until AppleScript, OCE, and QuickDraw GX ship, which may happen as
- late as this spring. I know that I have no real need for System
- 7.1 until I can use AppleScript and OCE, and frankly, at the
- moment, rumor has it that AppleScript, OCE, and QuickDraw GX don't
- work together. Of course, those who want to use multiple languages
- and international users will jump at the upgrade for WorldScript
- alone, although they'll have to wait like the rest of us for
- QuickDraw GX.

-
- Apple Catalog
- -------------
- Well, it's happened. Apple has started selling products directly
- to customers via mail order in The Apple Catalog. The catalog will
- contain Apple products, accessories, supplies, peripherals, and
- selected third-party products. We don't know if they'll offer cool
- Apple t-shirts from it or not, but we wouldn't be surprised.
-
- Sartorial sarcasm aside, did you send in your Macintosh
- registration card to get that free mouse pad or subscription to
- Macworld? It appears that Apple is going to use that list for
- pretty much the first time (well, they're informing affected
- PowerBook 100 users of the recall mentioned above, supposedly, and
- they might have used it a few times in the past, although I've
- never gotten anything from them in over five years). The Apple
- Catalog will go out to 1.1 million Apple users in the consumer and
- general business markets sometime in mid-October, and updates will
- follow approximately every 13 weeks.
-
- The propaganda claims that Apple will offer only "selected Apple
- Macintosh computer hardware products including the Macintosh
- PowerBook 145" and the third party products will come initially
- from Claris (surprise!), Aldus, and Kensington. Don't throw out
- your MacConnection catalog just yet, though, since aside from the
- small selection, all Apple products will be for sale at Apple
- suggested retail price of more money than you would pay anywhere
- else.
-
- You will pay for convenience since Apple will take orders around
- the clock every day. You can order by phone, fax, or mail, but you
- must pre-pay by check or credit card. Like other mail order
- houses, Apple will provide a 30-day money-back guarantee. You
- should get products quickly since Apple is aiming for next-day
- turnaround on orders taken by midnight Eastern Time and will ship
- products weighing less than 20 pounds overnight for free. Heavier
- items will ship free, but via surface. No word on how Apple will
- help if you want something heavier than 20 pounds shipped
- overnight.
-
- You receive a year of toll-free support directly from Apple on all
- Apple hardware ordered through the catalog, as well as help with
- installation, configuration, compatibility, and basic use.
-
- [I find Apple's one year of support policy intriguing. I'm curious
- if the help line will end up helping anyone who calls in with any
- question or, if not, what criteria they will use to turn away
- people who have called without being qualified for help. -Tonya]
-
- Interestingly, dealers can order from the catalog for customers as
- well, at which point Apple will ship the item to the customer
- directly. The dealer will receive a percentage of the sale in that
- case. Perhaps equally interesting, businesses can now order
- directly from Apple rather than going through the dealer network.
- Apparently large businesses dislike having to work with a dealer
- instead of with Apple directly, and the catalog will solve that
- problem.
-
- Overall, I'm unimpressed, mostly due to the prices. The Apple
- Catalog's shipping and warranty policies are in step with the rest
- of the mail order industry, but gone are the days when you could
- get away with either bad service or high prices. The Apple Catalog
- may be the only legitimate way to buy a Mac via mail order, and
- perhaps the premium will be worth getting a guaranteed clean Mac,
- but frankly, for everything else, I don't think that the good mail
- order companies should worry much.

- HFS Easter Egg
- --------------
- I came across these postings on Info-Mac a while ago and thought
- you might enjoy reading about how one finds a deeply buried Easter
- Egg.
-
-
- * Francois Grieu:
- I have discovered an obscure Easter Egg in the System 7
- implementation of HFS.
-
- When the Macintosh requests a disk because it's off-line, there
- are provisions for displaying a hidden message.
-
- Try it!! Rename a disk exactly to:
-
- KMEG JJ KS (this is 8 uppercase letters and 2
- spaces)
-
- Eject the disk with command-E so that you have a gray icon of it
- on the desktop. Now double-click on something in the disk and
- check out dialog box that wants the disk back. Oh well, it's only
- a message...
-
- Question: Who are dnf and ksct?
-
- Difficult problem: what's the name of their disk?
-
-
- * David N. Feldman:
- Congratulations - you have not only found the HFS Easter Egg in
- System 7, you've managed to do it in a way only vaguely imagined
- by the author of the egg.
-
- To answer your questions, dnf and ksct are David N. Feldman and
- Kenny S. C. Tung, the two Apple Engineers responsible for the
- extensions to HFS under System 7. The name of their disk is a bit
- less complicated than you make it out to be. You see, that string
- is triggered off of a checksum of the disk name. The intended disk
- name is "Like Wow Man. HFS For 7.0!" (the space after the period
- is an option space, just to be arbitrary) Your string, "KMEG JJ
- KS" just happens to have the same checksum, and so is greeted with
- the same message.
-
- When I wrote the patch at Apple, I wondered (ever so briefly) what
- the chances of a collision in the checksum space were. You have
- answered the question. For your interest, check out the code
- hanging off the pointer at $3EA in lomem. You should quickly catch
- the innocuous subroutine call which calculates the checksum.
-
-
- * Francois Grieu:
- Thanks for your kind answer, and for relieving my curiosity. Here
- is more on the checksum algorithm, and how I found this Easter
- Egg.
-
- As you may recall, the checksum algorithm zeroes D1, then does,
-
- ADD.B (A0)+,D1 ;add new byte from disk name
- ROL.L #3,D1 ;spread it around for each character in
- the disk name,
-
- and finally tests D1 against $7609F56D.
-
- The chances that a random name (over 10 characters long) matches
- the checksum is about one in 4000 million. Assuming a disk name
- per day per 10 million users for five years, the odds are that
- about four names would trigger the recognition. In practice, it's
- even less likely, for people tend to choose short names and the
- shortest name that matches is nine characters long, or 10
- restricting to usual characters.
-
- As a matter of fact, I didn't find the string "KMEG JJ KS" by mere
- chance; rather, I happened to break into the debugger at a
- location close to the checksum code, and got my eye caught by the
- CMPI.L #$7609F56D,D1. I took that as a late weekend puzzle. I
- found how it was called, and wrote a small program to construct
- matching strings.
-
- The program uses a simple heuristic varying the string (replacing
- wildcards in a template with characters taken from a chosen set)
- to minimize the bit distance with the checksum. The program finds
- matches within fraction of a second, because two nearly identical
- names tend to make nearly identical checksums.
-
- "KMEG JJ KS" is just a short, reasonably mnemonic string that
- worked. Another names that triggers the Easter Egg is "Hello world
- JS N A DTP".
-
- Using my algorithm, it's nearly impossible that I could ever
- reconstruct "Like Wow Man. HFS For 7.0!", especially with the
- option-space after the period.
