- CD-ROM Superstar
- ----------------
- They aren't fast, they aren't pretty, and they seldom connect to
- your stereo as nicely as you would like, but CD-ROMs are here to
- stay. They have found a niche in the market despite their many
- limitations because they provide an excellent way to disseminate
- lots of information cheaply. Someone at Macworld Expo in Boston
- was advertising a monthly CD-ROM disk, much like a monthly
- magazine (you thought wading through several hundred pages of
- Macworld or MacUser was hard, try making it through 650 megs of a
- CD-ROM). More reasonable uses of CD-ROMs are massive publishing
- projects for static information, such as parts lists and the like.
-
- The news is that Apple is going to step up the incentive to buy a
- CD-ROM player sometime next year by introducing a new, cheaper
- model and lowering the price on the current CD-ROM player. The
- cheaper model might even be included internally in future
- Macintosh models. That's kind of cool, but not all that
- impressive, other than that you might have a use for the $500
- that's burning a small hole in your checking account. No, the real
- scoop - and we hope that it is true - is that Apple will introduce
- at some point next year (note the ambiguous date) a CD-ROM player
- (oh boy, another one) having an access time of 28 milliseconds.
- "Big deal," you say, "my Quantum 105 is 19 milliseconds." Yes, but
- can your Quantum 105 read any CD-ROM disk, all 650 megabytes of
- it? Didn't think so. The fastest of the CD-ROM drives these days
- have around a 350 millisecond access time, which is pretty poky.
-
- This drive would be impressive if it were to happen, so I asked a
- knowledgeable friend if it could be done. He's not a CD-ROM
- expert, but he thought that the main problem was in the stepper
- motor and its control circuitry. Essentially, stepper motors work
- slowly in audio CD-ROM drives because there is no reason for them
- to step quickly. However, if a faster, more powerful stepper motor
- was used in conjunction with a well-designed microcontroller, a 28
- millisecond speed would be theoretically possible.

- Electronet, Yet Again
- ---------------------
- Yes, folks, it's passed into the trend phase. Wireless networks
- are all the rage these days, though none have made their way to my
- door yet. I heard the latest news from the strangest source, the
- evening news on the radio. Evidently, Motorola is introducing a
- new network technology called WIN, which stands for Wireless
- In-building Network. Unlike most of the competing wireless network
- technologies, Motorola claims that WIN will be capable
- (eventually) of speeds around 100 megabits per second. In
- comparison, LocalTalk - got it right this time, LocalTalk is the
- network hardware and software built into every Mac, AppleTalk is
- the overall network scheme and includes EtherTalk, LocalTalk, and
- TokenTalk - runs at about 230 kilobits per second.
-
- Motorola doesn't have a specific product ready, but they claim to
- have tested the technology at 50 megabits/second, though 15
- megabits/second will be the first speed at which products will
- run. For those of you who know what's where in the radio
- frequencies, Motorola has applied to the Federal Communications
- Commission (FCC) for licenses in the 18 to 19 gigahertz range,
- which is most commonly used by microwave transmitters.
- Interference would likely be a problem, except for the limited
- range (within a building) of WIN and the fact that Motorola's
- licenses would be the only ones within a 35 mile radius.
-
- While Motorola looks high in the radio frequencies, Apple is
- looking lower. Apple has asked the FCC to allocate the 1.7 to 2.3
- gigahertz range for high-speed data transmissions. We haven't
- heard anything about any Apple radio network products, but you can
- rest assured that the people who brought you AppleTalk, that
- "insanely great networking system," (to quote the Apple engineer
- who chided me on saying AppleTalk when I meant LocalTalk in a
- previous issue), are working on something interesting along those
- lines. I wouldn't be too surprised if General Magic's "Personal
- Intelligent Communicator" work was somewhat related.
-
- We expected to hear more about GEC-Marconi's Verran AC DataLink.
- It's the only electrical-line networking device that we've heard
- of that supports the Mac as well as the multitudes of PC-clones.
- It's not much as far as a network goes, as the company only
- recommends the 16 kilobits per second speed for sharing printers
- and the like, but in theory it could be used to share files. Even
- still, using the power lines is an efficient use of preinstalled
- wiring if you don't want to install network wiring all over the
- place as well. One way or another, the Verran AC DataLink is a
- start, though it could use a better name, but it would be nice if
- more of the innovative networking products showed up for the Mac.

- Faxing Printers
- ---------------
- We've long lamented the wastefulness of stand-alone fax machines
- when most of the components of them could be used with a computer
- to further increase productivity. After all, a fax machine is
- little more than a bad scanner, a poor printer, and a one-way
- modem in a single box.
-
- Fax modems have helped somewhat by providing a data modem and send
- fax capabilities in one unit, but the printer and the scanner are
- still left out. A couple of new products for the popular Hewlett-
- Packard LaserJet II line of laser printers may help change that,
- even for Mac users. The first of them, FaxConnection from Extended
- Systems, comes in two flavors, a $595 plug-in board for the
- printer and a $695 external box that attaches via parallel cable.
- Both products sit between the printer and the computer and connect
- to the phone line to receive faxes. A 256K buffer will store about
- 12 pages of standard Group III text (though be warned that the
- standard page of text used in these figures is ridiculously empty
- of text - we've seen it).
-
- The second product, Tall Tree's Fax-O-Matic, is like the external
- version of the FaxConnection in that it is an external device that
- connects in the same manner. The main differences between the two
- devices are that the Fax-O-Matic has a 512K buffer and an
- automatic scaling feature that will take a legal sized fax and
- shrink it to fit on a letter size piece of paper. Fax-O-Matic
- costs only $399.
-
- These would seem to be limited to the PC-clone users who also have
- HP LaserJets, but since both the external version of FaxConnection
- and the Fax-O-Matic device are external devices that connect via a
- parallel cable to any PCL (Hewlett-Packard's Printer Control
- Language) printer, other printers might work as well. We'd like to
- see one of those devices working with the QMS-PS 410, which can
- automatically switch between AppleTalk and parallel ports and
- related emulations without user intervention.
-
- We would also like to see fax machines so integrated into computer
- setups that the fax would only print on paper if no RAM or disk
- space was available to hold it. Sending and receiving online makes
- more sense in terms of paper waste (thermal fax paper cannot be
- recycled) and usability - often a faxed form would be more useful
- in machine readable form. The most advanced form of this now is
- Steve Jobs's NeXTstep 2.0, which includes full fax support in the
- operating system. Now if only the NeXT fax modems could be smart
- about keeping files in machine readable form if another NeXT is on
- the other end...

- HYPERTEXT '91
- -------------
- [Editor's note: We're including this notice on the hypertext
- conference not because it is big news, but because we believe that
- the future of information dissemination lies in electronic
- systems. Once information (of any sort, from TidBITS articles to
- baseball statistics to avant garde fiction) is stored
- electronically, we must have some method to organize and explore
- the world of our information. Despite what critics say, hypertext
- (in some general form) may well be the only answer to the
- information glut. More specifically, the top contender for
- hypertext information management is Ted Nelson's Xanadu system,
- which is also the subject of the first TidBITS Special Issue,
- coming soon to the electronic newsstands of the world. In any
- event, if you are interested in hypertext, this the conference to
- attend to see the latest and greatest. We hope to be there if at
- all financially possible.]
-
-
- Preliminary Call for Participation
- Third ACM Conference on Hypertext
- San Antonio, Texas, USA
- December 15-18, 1991
-
- Hypertext '91 is an international research conference on
- hypertext. The ACM Hypertext Conference occurs in the United
- States every second year in alternation with ECHT, the European
- Conference on Hypertext.
-
- Hypertext systems provide computer support for locating,
- gathering, annotating, and organizing information. Hypertext
- systems are being designed for information collections of diverse
- material in heterogeneous media, hence the alternate name,
- hypermedia.
-
- Hypertext is by nature multi-disciplinary, involving researchers
- in many fields, including computer science, cognitive science,
- rhetoric, and education, as well as many application domains. This
- conference will interest a broad spectrum of professionals in
- these fields ranging from theoreticians through behavioral
- researchers to systems researchers and applications developers.
- The conference will offer technical events in a variety of formats
- as well as guest speakers and opportunities for informal special
- interest groups.
-
-
- Suggested Formats and Topics
- We are inviting you to participate in HT'91 in one of seven
- different areas of the technical program: papers, panels, courses,
- videos, technical briefings, posters, or demos. Submitters may be
- invited to participate in the technical program in a different
- category from that in which they submitted their work.
-
-
- Submissions in all areas of hypertext research are encouraged.
- Topics of interest would include the following:
- Paradigms for information access
- Information design
- Theories, models, and frameworks
- Experimental or observational studies of use
- Workplace deployment issues
- Structuring hypertext documents for reading and retrieval
- Underlying technologies (persistent object stores, link
- services, databases, information retrieval, access control)

- Cool Technologies
- -----------------
- We've already talked about the latest networking technologies from
- Motorola and possibly Apple, but other truly neat technologies
- have recently shown up.
-
- Storage-wise, we haven't heard anything more about Canon's optical
- card, but Intel should be shipping new Flash Memory Cards in a
- month or so. These cards are non-volatile, memory IC cards and
- come in 1 and 4 meg models. In theory, the cards are DOS-
- compatible storage devices, but currently there isn't any way to
- alter data at the file level, so they are limited to storing
- programs and read-only documents. Eventually, there should be no
- difference between a Flash Memory Card and any other storage
- device, at which point they might even show up in a future
- Macintosh laptop.
-
- We also heard a bit about something called optical paper, which is
- a flexible mylar film that can have data written onto it with a
- laser. The laser makes permanent holes in the film, so the optical
- paper is a new example of WORM technology. It sounds like it could
- replace magnetic tape archives for mainframe type computers, but
- we suspect that microcomputer applications of the technology would
- not be far behind.
-
- Another new technology isn't being used to store data (though
- that's not an impossibility), but can be used for numerous other
- applications. A new class of plastic-like polymers can conduct
- electricity when properly doped with certain chemicals. One
- initial use for the polymers has been in rechargeable batteries,
- but the polymers have a host of other abilities, including the
- ability to shrink and grow, to change colors, and to emit light.
- That last ability has prompted some people to look into ways of
- using the polymers in computer screens, though researchers haven't
- yet found a way to prevent the electrical features of the polymers
- from disappearing over time, especially in the presence of heat or
- air. One IBM research scientist said in the Wall Street Journal
- that IBM is looking into ways to use the polymers in conventional
- computer chips.
