The following material comes from the Raised Dot Computing Newsletter. The Raised Dot Computing Newsletter is published bimonthly, and is available in audio, large print, and disk editions. Subscriptions are $20 for audio, $18 for print, and $30 for disk. The disk edition is in PC or in Apple II/BEX formats. For more information, contact: Raised Dot Computing 408 S. Baldwin Street Madison, WI 53703 (800) 347-9594 CD-ROM Technology is here -- David Holladay In January, 1975, I attended a course at MIT on microcomputers. Besides learning all about microprocessors and microcomputers, I got a peek at a future technology. We discussed the Phillips/MCA project to put movies on laser disks. We realized that these laser disks could hold enormous amounts of text data (several billion characters each). We dreamed of getting a massively indexed, encyclopedia on a single disk. We dreamed about a service that would provide, on a monthly basis, full text of all general interest magazines. We realized the implications of packing billions of characters of data on a single disk. What we could not have anticipated would be how useful this technology would be for blind persons. For a sighted person, this technology represents marginal improvements in search time, in cost, and in storage space. To a blind person, this technology represents volumes of text that can be read with a talking computer. The disks are small, easily stored, and easily carried. Usually the data can be quickly searched (because most disks also contain massive cross-indexes). CD-ROM Technology Over the last few years, many of these ideas are coming to pass. The technology is called CD-ROM. CD-ROM stands for Compact Disk Read Only Memory. The disks are almost identical to conventional CD-Audio disks. In order to take advantage of the information on the CD-ROM, you must have a CD-ROM disk drive connected to your personal computer. Each CD-ROM disk has the capacity for holding about 640 million characters (this is less than the capacity of the larger 12-inch laser disks used to store movies). One of the main differences between CD-ROM drives and home CD-Audio players is that CD-ROM drives have additional error detection and correction circuitry to minimize errors (slight errors would not make a noticeable change to music, but would garble text data). The disks themselves cannot be altered or erased by the user (just as an individual cannot alter a CD-audio disk). A CD-ROM is not an alternative to floppy disks or hard disks because it is read-only. As far as the general market is concerned, CD-ROM is a publishing medium. It is an alternative to inkprint publishing. CD-ROMs have been most successful for publishing large documents which would be expensive to distribute in another format. CD-ROMs also compete against on-line databases. Against the costs of a CD-ROM and the disk drive, you can weigh the access charges and the long-distance telephone charges. In general, people do quicker and more thorough searches when they are using a CD-ROM based system. CD-ROMs cannot compete against databases which change rapidly (like airline schedules). It is too difficult to be constantly producing and distributing new disks. CD-ROM Use Today Right now, there are two basic families of CD-ROM disks; those designed to work with the MS-DOS machines and those that are designed to work with the Macintosh. Some disks have been issued for both formats. Because of the difficulty blind people have in using the Macintosh, this newsletter will focus on PC-based applications. If you want more information about CD-ROMs and the Macintosh, get the catalogs from the CD-ROM vendors mentioned later in this article. Over the last five years, there have been very rosy predictions about the potential of CD-ROMs. Many of these predictions did not come to pass. It was a classic cars and roads problem. (At the turn of the century, no one wanted to build many roads since there were few cars; few wanted to buy cars since here were few roads.) Few general CD-ROM disks were produced since there were not many people with CD-ROM drives ready to buy disks. Few people bought CD-ROM drives since there were not many titles available to make the purchase worthwhile. CD-ROMs have been very successful in specialized applications. One example is giving access to the enormous database of chemical substances and their effects for use in a poison control center. In this situation, one vendor provides a system with a computer, a CD-ROM disk drive and a CD-ROM disk. While this is an interesting application, it is unlikely that anyone in the general population will want a copy of "poison index" CD-ROM. It also is unlikely that anyone in the poison control center would want to read any CD-ROM except the one that contained their data. As long as CD-ROM systems were used in specialized applications, it was unlikely that general interest applications of CD-ROM technology would see the light of day. Beginning in 1987, general interest titles on CD-ROM began to appear. Microsoft Corporation lead the way. Microsoft produced several titles, and sponsored several conferences to attract interest in this field. To get a better idea about the current state of CD-ROMs, I called Judy Dixon. Judy Dixon has been an involved consumer of sensory aids equipment for many years. She is the consumer relations officer at the National Library Serivce for the Blind and Physically Handicapped. She now collects CD-ROMS as a hobby. As she told me, "I like to look things up". Her favorite CD-ROM is called the Microsoft Bookshelf. This is a collection of 10 reference books (a dictionary, A thesaurus, a book of quotations, a Zip Code directory, etc.). All these applications are available as easy-to-use TSR applications. In other words, she can look something up in the dictionary while using her word processor. The Microsoft Bookshelf CD-ROM disk costs $199. Another favorite is the CIA World Fact Book, a disk which costs $89. It contains profiles of 248 different countries and territories with lots of statistical data. According to Judy, Iraq has (or at least used to have) 68 AM Radio stations, 1 FM station, and 81 TV stations. Judy has recently ordered the 1991 World Almanac for $65. All told, Judy has close to 20 different CD-ROM disks. According to Judy, the National Library Services for the Blind plans to put its complete catalog (over 100 megabytes) on CD-ROM. This project will be completed in about 18 months. Using such a disk, a blind person could quickly search the entire database in seconds for books they need. Judy supplied me with several sources of CD-ROM disks. CD ROM, Inc. has a catalog in print and on audio tape. Their number is (303) 231-9373. The Bureau of Electronic Publishing has a catalog in print. Their number is (201) 808-2700. We would appreciate learning about any other significant sources of CD-ROM disks. A good source of information is the CD-ROM forum on CompuServe. There is a magazine called CD-ROM End User. It is free to qualified persons (i.e. those with a CD-ROM system). Call (800) 688-3374 to get an application form. The magazine has plans to start issuing a disk edition for the visually impaired this spring. Many CD-ROM disks are still quite expensive. It is my understanding that the manufacturing cost of a single disk is about $3. Many CD-ROM disks cost over $1,000. The high price tag is due to the enormous cost of preparing the data, mastering the data, preparing the indexes, and linking in the searching software. Some disks are priced high based on low sales projections. I hope that once the general market for CD-ROMs picks up, prices will move down to more reasonable levels. Package Deals Right now, two companies are offering special deals: a CD-ROM drive, all the materials to get you connected to a PC, plus 6 CD-ROMs; all for about $700. The deal from DAK is described in detail in the next article. The Bureau of Electronic Publishing is also offering a package deal. It is described in the article Some Selected CD-ROM Titles. There is no doubt that CD-ROMs will play an important part in providing information to blind persons. As with all technologies, CD-ROMs have their problems. As we will see in the next article, CD-ROM systems need lots of memory. They use special drivers which may conflict with other pieces of equipment in your system. Most CD-ROM disks want to load their searching software on your hard disk. Each CD-ROM disk seems to have its own user interface (a different set of window sizes and shapes, different ways of showing the cursor, different commands, and different ways of approaching the problem of searching massive amounts of data). As each new technology comes out, it takes a period of time for the technical kinks to be worked out. The easier things get, the more people there are who can take advantage of the technology. If there is sufficient interest, this newsletter can be a source of information to assist people who want to get started on CD-ROM technology. CD-ROM offering from DAK A month ago, Caryn and I took the plunge into the world of CD-ROM computing. We bought DAK's CD-ROM package and installed it in our home computer. DAK is a large consumer electronics mail order firm. They are offering a package deal of a BSR CD-ROM disk drive for MS-DOS computers and 6 CD-ROMS, all for $718. According to the DAK catalog, the 6 CD-ROM disks cost $2,400 if purchased separately. From my inspection of different catalogs, I believe this is accurate. The six disks are as follows: -- A World Atlas -- A U.S. Atlas -- The Grolier's Academic American Encyclopedia -- "The Library of the Future" (a collection of 450 short stories and books which are out of copyright) -- An 8 volume Reference Library (dictionary, thesaurus, and other reference books) -- "Languages of the World" (a collection of multilingual dictionaries) Of these 6 disks, the World Atlas and the U.S. Atlas are graphically based and cannot be used by a blind person. But the other four disks are almost entirely text based. We had no trouble using Flipper and the Audapter to access the non-atlas disks. These disks did contain some graphics, though. The encyclopedia disk contains some images (mostly of different breeds of dogs, cats, horses, dinosaurs, plus a selection of presidential portraits); the "languages of the world" disk uses graphics to show Japanese and Chinese characters on the screen. What you need In order to install the CD-ROM system, you need several items: -- The DAK CD-ROM package -- A computer system with at least 1 megabyte -- DOS version 3.1 or higher -- A memory manipulation program like Quarterdeck QEMM to hide device drivers in high memory -- Some available hard disk space -- An EGA or VGA monitor if a sighted person is going to view the screen -- A mouse for the use of a sighted person using the electronic atlases -- Some screwdrivers to remove the cover of the computer and install the disk controller card Installing the Drives At home, we have a 386SX computer with 1 megabyte of RAM. Installing the drive was easy. It was a matter of removing the cover, inserting a card, connecting a cable from the card to the drive, and plugging the CD-ROM drive to the wall outlet. There was no need to change any DIP switches. The system comes with clear instructions from DAK designed to help a novice computer user. About the only thing that had me concerned for a few moments is the fact that there are two data jacks on the back of the CD-ROM drive, but only one data cable to connect to the computer. It turns out that it does not matter which jack you use (the other jack is there in case you want to add an additional CD-ROM drive to your computer system). Installing the Software Installing the software to run the system was another matter. DAK includes its own installation program. In order to use DAK's installation program, you have to use your cursor keys to move a pointer around the screen to simulate a mouse. As long as you are sighted, running the installation program is very easy. It is impossible to use if you are blind. I have prepared a disk containing all the instructions and software you need to install the DAK package on your computer. Contact me for details. After running the installation program, there were two things I did not like about the software that was loaded. The first problem was that in order to get into the CD-ROM software and in order to select applications, you had to use a sighted-type menu just like the installation program. The second problem is that the system loaded quite a bit of software onto our hard disk. I soon discovered that the CD-ROM drive was treated as a disk drive with the letter code S. I wrote a series of batch files to get access to the different applications. For example, in order to get into the encyclopedia, I just type ENCY at the command line. After a bit more experimentation, I found out that quite a bit of the software that was loaded onto the hard disk is also available on the CD-ROM itself (but hidden in a subdirectory). I wiped out this duplicated software from our hard disk. I modified the batch files so that when an application is used, the appropriate software is copied from the CD-ROM to the hard disk before it is executed. When you leave the CD-ROM application, the appropriate files get deleted from the hard disk. This technique really cuts down on amount of hard disk space permanently allocated to the CD-ROM system. Memory Problems The software drivers for the CD-ROM drive and the CD-ROM software use a lot of memory. Caryn found out to her dismay that the the drivers on the CD-ROM drive took up enough memory to prevent EasyScan (the simple front end to the Arkenstone Reader written by Personal Data Systems) from working. It was clear that we were out of memory. Solving the memory problem was a two-step process. I needed to change the configuration program on our computer so that the computer knew that there was more than 640k in the system. Next I needed to purchase a copy of QEMM from Quarterdeck. This is a program that uses high memory (the memory between 640k and 1024k) for device drivers, DOS buffers, and other software tools to support your equipment. This frees up over 100k in the lower 640k. Once QEMM was installed, we had no more memory problems. We could use the Fax software, the CD-ROMs, Flipper, and the Arkenstone without any problems. Based on my experience, I would not want to use a CD-ROM drive on a computer with less than 1 megabyte of RAM. One footnote: installing QEMM was not easy. When I started using QEMM, I had problems with the Arkenstone. I quickly discovered that the Arkenstone was using high memory $DC00 through $DFFF. I had to tell QEMM to leave this block of memory alone. I tell this story to remind people that sometimes the fixes need fixing. QEMM only works on a 386 or a 386SX. You need a piece of software that can store your device drives and DOS buffers in the area of memory between 640k and 1 megabyte. If you have a 286, use another product, like AMS Hicard2. Contact your computer dealer for details. Access Technology For access technology on our home computer, we use the Flipper screen access program with the Audapter speech synthesizer. By sheer coincidence, both of these items are available from Raised Dot Computing. We have not done any experimentation on how well CD-ROM drives work with any other screen access program other than Flipper. We have heard some reports that some access programs have difficulty working with CD-ROM drives. We are in no position to confirm or deny this. We are happy to provide Flipper demonstration disks to anyone who wants to compare programs. The Environmental Variable Space If you look at your AUTOEXEC.BAT file, you will probably find several lines starting with SET. These lines create environmental variables. MS-DOS only allows a limited number of characters to be used for environmental variables. While we had no problem with our system, we understand this can be a problem area for some CD-ROM systems. Some CD-ROM systems have so many variables that they fill up the environment area. When this happens, different program modules do not know what they are supposed to do. If you run out of environment space, you need to make more room, either by enlarging the space or by deleting unnecessary variables. There is probably a line in your CONFIG.SYS file that looks like this: C:\COMMAND.COM /E:350. In this example, there is a limit of 350 characters for environmental variables. In general, you want to keep the maximum size as small as possible. Because of the structure of DOS, the environmental space is duplicated many times when most programs execute. Thus any wasted space is multiplied many times. You may have to write some batch files to clear out the environment space to make room for your CD-ROM software. If you issue a command like C:\COMMAND.COM /E:750, you make room for more variables, but you also clear out all the existing variables. Since I have not had any problems with this, I am reluctant to offer step-by-step advice. You may have to consult an expert computer user for help. The Caddy Problem One aspect of the CD-ROM drive that I did not anticipate is how the CD-ROM disks are loaded into the drive. You need to take the compact disk out of its plastic holder to put it into a different holder called a "caddy". The caddy protects the CD-ROM disk the same way the casing of a 3.5 inch disk protects the magnetic media. There is a window that only opens up when the caddy is inserted into the drive. The DAK package contains a second spare caddy in case you lose one. A blind user may feel more secure if additional caddies are purchased so that each CD-ROM disk can live in its own caddy permanently. I found a mail order company that sells the kind of caddy I needed. There are three kinds of CD-ROM caddies: Phillips, Sony, and NEC CDR-77/80. The DAK drive uses Sony caddies. I bought a set of 5 at $10 each so that each of the CD-ROM disks from DAK can live in its own braille-labeled caddy. The source I found was Educorp (a supplier of Macintosh software and the largest suppier of Macintosh CD-ROMs); their number is (800) 843-9497. Caddies for the DAK BSR disk drive are item #1321 in their catalog. Summary of Installation Within an hour of opening the crate from DAK, we were reading data from CD-ROMs. Installing the CD-ROM system was easy. The hard part was making sure that the installation of the CD-ROMs did not disrupt any program that was already there. Make sure you have enough memory, and that you can hide your device drivers in otherwise unused portions of memory. Using The DAK CD-ROMs Once the software is installed, using the CD-ROMs is easy. You turn on the drive. You insert the caddy containing the CD-ROM disk. You type the name of the batch file to start up that application. The Atlases: Fun for Sighted People In the collection of six disks from DAK, two cannot be used by blind persons. These are the two Atlases. One contains maps of the United States, the other contains maps of the World. The program is totally driven by the mouse. You click on a portion of the World Map to indicate a region you are interested in. Once the regional map pops up, you click on the individual nation that you want. The maps are clear and sharp. My major complaint is that I want to be able to continue to magnify any portion of the world indefinitely. I like having a map of Iraq or Kuwait, but I want to also have a street map of Baghdad. The Encyclopedia The Grolier Electronic Encyclopedia is the best of the lot. It is an enormous work of over 400 megabytes. We have been pleased with the text. We looked up subjects that we were very familiar with, like Guide Dogs, and found the text to be a very accurate description of the training and use of guide dogs. The user interface is very easy to learn. You press enter to get past the opening screen. You get to a screen which offers a choice between three selection methods: word search, browse titles, and browse word index. Usually word search is preferred, so just press enter again since this is the default. Word search allows up to four words or phrases that must be present in an article. If you wanted to find all articles containing the words "Roman" and "army", just type in each word followed by enter. Press enter an additional time to start the search. If a few seconds, the program tells you how many times this combination appears in the entire encyclopedia. Press enter again to get a list of the article titles that contain this combination. Each title appears on a separate line, along with the number of times the words appeared in the article. Move through this list with the up or down arrow keys. When you want to make a selection, just press enter. The text of the article appears in a text window that takes up about half the screen (from the 6th line to the 18th line of the screen). Press Alt-Z to enlarge the window so the text fills the screen (except for a few status lines). When you want more text, press the page down key (or use the page up key to move back). If there is a mention of something with its own article in the encyclopedia, it is in all caps. If you get the cursor on that name and press return, you open a new text window with another article. Reading cross-references has never been easier! It is very easy to copy an article to a textfile. Press Alt-K, then the down arrow key followed by enter to select "all" (i.e. the entire article). Then press the up arrow key followed by enter to begin saving. You are prompted for a file name. The system uses the extension "ART". Once you have a textfile, you can turn it into braille using Hot Dots. Or you can merge the text into your term paper. The Library of the Future The Library of the Future is a collection of over 450 short stories, plays, novels, and historical documents. It contains most of Shakespeare, the Bible, War and Peace, lots of Sherlock Holmes, and much more. The hardest thing about it is understanding the interface to select a document. You end up looping through the selection process twice. First you give some selection criteria (author, country, time period, subject matter, etc.); then you are offered a list of titles which meet these criteria. It takes some use of the disk to learn when to use the enter key and when to use the spacebar to select an item. Once you get into a document, reading is a matter of using the cursor keys (or Page Up or Page Down). Languages of the World The Languages of the World disk is a series of multilingual dictionaries. The program is a TSR (terminate and stay ready, it hides in memory until you call it up). The program is designed to be used inside your word processor. The "hot key" combination to call it up is Alt-space. The first time you press Alt-space, you get to set up the program. You declare your source language and your target language (it supports 13 different languages), you specify which dictionary to use, and how detailed you want the searches to be. To specify these options, you only use the four arrow keys. If you press the enter key, it really fouls things up. After a little experimentation, I used the program to write some sentences in Norwegian. I know that there are software packages that act as automatic translators. The "Languages of the World" disk has no such software. If you are going to use it to write in another language, you need to know something about the grammar, word order, verb conjugation, etc. of the other language. Reference Library The Reference Library is a collection of 10 reference books. This collection is different from the Microsoft Bookshelf, another collection of reference books on CD-ROM. It is my understanding the Microsoft Bookshelf is fairly easy to use. In contrast, the Reference Library in the DAK collection is more difficult. Despite my grumbling, it is a useful disk. Using the dictionary, I was able to understand the origin of Scud as a name for a missile (a Scud is a cloud formation which indicates bad weather is coming; a very bad joke when you remember that the first Scuds contained nuclear weapons). The Reference Library has three separate screen areas. The right column selects which reference book you are using. The top line selects the menu option (i.e. Search, Browse, Quit, etc.). The bulk of the screen is called the View Window, where you actually read the text in each book. When you want to switch between giving a menu command and selecting a reference book, press the tab key. To select browse, use Alt-W. To select search, use Alt-A. To exit the program, press Alt-X. Summary If you can afford it, and if your computer has at least 1 megabyte of memory and some free hard disk space, give CD-ROMs a try. The Grolier Encyclopedia is the one disk which makes the DAK package really attractive. When you buy from DAK, you have a 30 day free trial period. If you are not satisfied for any reason (within the first 30 days), you can return it for a full refund. The order number for DAK is (800) 325-0800. The BSR External CD ROM Drive with 6 CD ROM disks costs $699 plus $19 for shipping for a grand total of $718. This is item number #5719 from their catalog. Another Package Deal The Bureau of Electronic Publishing has a deal called The CD-ROM Bundle, designed to compete with the DAK deal. For $689 you get a Phillips CD-ROM drive and all the parts you need to get it working with a PC, plus their own collection of 6 CD-ROM disks. These six disks are: Microsoft Bookshelf, U.S. History on CD-ROM, Sherlock Holmes on Disc, Shakespeare on Disc, Birds of America, and Software Potpourri (Software Potpourri contains the King James Bible, assorted shareware, and a movie database covering several hundred films). Some Selected CD-ROM Titles Here are some selected items from the catalogs of The Bureau of Electronic Publishing [BEP] and CD-ROM Inc. [CRI]. This listing focuses on text-based disks for the PC. More information about each disk is available in the catalogs from these vendors. For the address of the vendors, see Facts on File. The Bureau of Electronic Publishing offers an on-line CD-ROM library. If you have a modem on your personal computer, you can take a CD-ROM on a "test drive". First call (201) 808-2700 for a "CD-online password". Then have your system dial (201) 808-0085. Set your communications parameters for no parity, 8 data bits, 1 stop bit, full duplex, and echo off. The software first asks for your terminal type (VT-100 or whatever). Then key in the password you have obtained. You may use any of the listed CD-ROM titles for up to 10 minutes at a time. Titles available are changed periodically. This system is designed for demonstration and sales purposes only. About Cows The full text of a book about Cows including many drawings.
