From: xx004@cleveland.Freenet.Edu (Atari SIG) Subject: CLEVATARI - March 1990 Date: Tue Mar 1 16:39:37 1994 EDITORS NOTES: author Randy Hahn (CLEVATARI NEWSLETTER, Issue #101, March 1990) This month has been a trying one for Atari Owners. We still haven't seen any STe's or TT's except in magazine articles. It's even hard to find 1040's or 520's execpt on the used market and an Atari monochrome monitor is one of the scarcest hardware devices in the U.S. We band together like revolutionaries and try to change the world into believing what we already know to be true -- namely that Atari computers are best. Unfortunately, we sometimes are frustrated and bewildered by the failures of developers who don't deliver as fast or as perfectly as some would want. I hear so many shallow views of one developer right now...Avante-Garde. These views come from so many "experts" who apparently know how it is to develop in a world of unknowns. Well, I would like to set a different tone for a moment. That is to congratulate Avante-Garde for being persistent, innovative and patient with the very public which they have so richly supported for so long. Maybe we have forgotten about Avant-Garde in their success of PC-Ditto, the almost unbelievable hardware free IBM emulator an honor they granted to our favorite computer!! If we were to believe the opinions of the most frustrated we would never have gotten to where we are today with respect to computers. Progress would be at a standstill, and computers would be a thing of the future not the present. No one would ever dare to try anything innovative as Avante-Garde has tried in the past and the present. OK, it isn't running yet, but that doesn't mean that we should give up on them. Nothing is perfect, including the very computer that we own -- how quickly we forget. Atari doesn't even appear to support their computer as well as Avante-Garde has supported real clients (not just bystanders). You might remember Page Stream had a similar problem when they first introduced the bug riddled version of their product. With all the owners they have today, you may easily forget all of the negative feelings, ridiculous accusations and bad remarks we heard about Soft Logic just 6 months ago!! We forget all of that as we run out to purchase what could be the best desktop publisher for the Atari ST. So why are all of these negative feelings amassed over Avant-Garde? They are standing behind their product and working long and hard to correct the problems which have been identified with their product. They aren't giving up like some of the Atari supporters of the past!!! I am proud of the fact that I purchased an advance copy of PC-Ditto II. I still have no doubt that Avant-Garde will make good on PC-Ditto II because they can see beyond the exaggerations and frustrations portrayed by some of the public which is turning on them now. I only hope they keep the faith with those of us who look to the future and don't stoop to the ridiculous opinions heard (some of which come from non-purchasers). I have called Avante-Garde three times and have had them answer all three times to be treated with respect, and courtesy all three times. They have encouraged me that they are earnestly interested in any problems and are working very hard to reconcile those problems. Avante-Garde has offered to return my money twice and as far as interest lost in the bank so far I have lost $3.50 (which I really can't get that upset over - could you?). I hope you can believe that over any third and fourth party opinions which are filtering to the public in written articles based on sketchy information or hype. If you truly believe in Atari computers please support and encourage (not discourage ) anyone who supports the Atari with developement. For without your encouragement, there may not be much of a furture for our enjoyment and livelihood. Support the REVOLUTION! (tm) ST DISK CATALOG CLEVELAND ATARI COMPUTER ENTHUSIASTS ST ATARI NORTH COAST ENTHUSIASTS by Joe Adato (CLEVATARI NEWSLETTER, Issue #101, March 1990) This is the current ST Disk Catalog available to the user group members in the Cleveland area. The disks are available at B & G Electronics and may be borrowed without cost by members for two days. At the meetings disks will be available for $2.00 each. In addition programs are sold individually, so that you may put as many programs as will fit on each disk and only pay a per disk price of $4.00. Questions should be addressed to the current ST Librarian. On disks for sale all files are ARCed unless otherwise indicated in the catalog. The size of the ARCed file is listed in parenthesis. DISK 3: This disk contains seven (7) ARCed files. A brief description follows below. ACC5.ARC (99,584): There are five desktop accessories in this file: Bigmouth (it will tell you jokes), Fortune (get your fortune told), New Word (Complete with documentation, this is a desktop word processor), Notepad (write and save notes), and Diskman (one of my favorite disk utilities). ARKSHELL.ARC (17,434): This is the shell program to use with ARC.TTP. It is one of the better shells for this program. CHECKERS.ARC (24,068): This is the popular checkers game. However, the graphics are nonexistent and the program is not too flexible. CIRCLE2.ARC (20,991): The program works with Fractals and is a good demo. MICROCHK.ARC (81,280); Microcheck was my favorite check processing program on the 8-bit. This is the ST version, which has several additional options for sorting and maintaining more than one account. MONOPOLY.ARC (71,609): This, the popular board game Monopoly, is not quite finished. Anyone with programming skills is welcome to work on it. Please note that the computer cheats! READER22.ARC (42,877): This is a very useful program which allow you to view text, on the screen, as if it were a printed page. you can move forward, back or proceed to a desired page. It is even possible to print particular phrases of portions of the text. This program is shareware and comes with complete documentation. DISK 4: There are fifteen (15) ARCed files on this disk. AGGRIV.ARC (50,842): This is a version of the game Aggravation. It needs low resolution. CALC.ARC (12,259): The file contains a program to create a very simple calculator (+.-.x.:). There are many better calculators and most are accessories. CHKDSK.ARC (19,205): The program is supposed to check your drive. It is a TTP program with no documentation and I could not figure out how to use it. DISKZA.ARC (4,546): All I got were two bombs. Any suggestions? GRAPH_3D.ARC (52,525): This is a demo of a 3 dimensional graphing program.MISCTOS.ARC (29,608): The file contains three totally unrelated programs, but useful. MILESTON.ARC (73,522): This is the ARChed file to the popular game of the same name. First run GRABASRO.BAS, then choose the appropriate program. The game runs in Low Rez. MISCTOS.ARC (29,608): The file contains three totally unrelated programs, but useful. MAZMAKER.TOS will draw a maze to a printer or to the screen. SEEKTEST.TOS is a disk drive diagnostic, set the rates and run; the program prompts you. XREF.TOS will print a cross-reference of a Basic program. MOUSEICN.ARC (8,771): Two programs are in this file. One demonstrates the various forms the mouse pointer can take, the other makes Mickey Mouse the pointer. RAMDISK.ARC (3,456): The programs included will set up a ram disk between 64 and 768K. Documentation is included. The ram disk is supposed to survive resets and changes in resolution. RD1040.ARC (4,865): Another ram disk, this one is an Accessory with documentation. It only works with 1 meg or larger machines. SPELLPLS.ARC (25,795): A spelling checker program that works with 1st Word, this files contains documentation and instructions for setting up your own dictionary. STSCOPE.ARC (15,407): This is an ST Scope Memory Utility; it will display the contents of memory and allow you to change it. Once run, press 'HELP' for a list of commands. You should know what you are doing before you use this utility! UE.ARC (20,612): This is the famous MicroEmacs Editor, a text editor for programmers. No documentation is included. VOLUME.ARC (1.920): This program should change the volume name on a disk. It doesn't seem to work, however. WRDCOUNT.ARC (11,114): A desk accessory that will count and list the number of words in any text file. (Note: Two or three disk listings will be included in each issue as room permits) GRAPHICS and DESKTOP PUBLISHING - Part II author Randy Hahn (CLEVATARI NEWSLETTER, Issue #101, March 1990) As discussed in the previous issue, there are two basic types of graphics forms which currently exist for use namely "line drawing" or "bit-mapped". We described the basic differences and the ways in which the graphics were both represented. Now, on to a discussion of where and when to use them. Unfortunately, it really isn't a matter of which kind of graphics type to use but rather when each type could "best" be used to represent the picture or graphics in a particular application. As described last time, the bit-mapped type of graphics uses a pixel by pixel representation of the art work. It is therefore capable of very nicely creating art work with subtle shading, fine lines or irregular shapes. Image scanners often are used to save this type of image, because they can distinguish the subtle shades of gray in a photograph or other art work when used at the higher "dots-per-inch" settings. Unfortunately there are a couple of drawbacks when dealing with bit-mapped images. First of all, since bit-mapped images are representing a piece of art work by defining each and every pixel, they routinely takes much more memory to save on disk and also take up more memory in the computer as they are being used. This is why one of the options of most desk-top publishing packages is the ability to show the outline of a picture but to turn-off the actual picture from being shown on the screen. Turning off pictures can greatly speed up the whole operation of desk-top publishing when the screen is re-sized and scrolling takes place. Otherwise, bit-mapped images greatly slow down the process of desk top publishing because of the memory use. Secondly, a bit-mapped image doesn't fare as well with a massive reshaping and/or re-sizing of a piece of art work. It will usually represent a picture quite well when it is used at exactly the same size in which it was scanned, but, bit-mapped images which are re-sized have to make many decisions about how to represent each pixel when it is split or combined with other pixels around it. Since a computer cannot base its decision on "how it looks", but on shear programming algorithms, the decision and the outcome of a re-sized bit-mapped image usually leaves something to be desired (especially in massive scale changes). As was stated last time, line-drawn (or vector-oriented) graphics use mathematical descriptions to represent images. They are most often used in graphs (line, bar or pie shaped), flow charts and schematic type drawings since they are made up of mathematical shapes already. The ease of duplication, movement (plus subsequent repainting on a screen) and re-sizing are all advantages of the line-drawn images. This is the most typical type of graphics used with Computer Aided Design (CAD) because of the ease of setting up a symbol library for component type drawings. Re-sizing of this type of graphics faithfully retains the proportions of the original, and thus is most useful when one is trying to reduce or enlarge a drawing from its original size particularly when trying to "cram" a full page image into 1/4 page of a desk top published newsletter (or vice verse). The biggest drawback of line drawn images are that subtle shades and hues are virtually impossible to represent mathematically. Therefore, "true art" or photographs cannot be used efficiently with line-drawn graphics packages. In summary, to insure the best possible results, each image must be evaluated for the best compatibility with other graphics packages and translated if necessary to allow the best possible use. One must also consider the original size versus the final size of the art work as well as the shades and hues of the art when first scanning or creating the image. Much of the time, original art work can be scanned in one type of image and translated into other types when transferred to a "paint" package or other graphics art packages. The art work can be touched-up and also saved in other common formats for better manipulation of the art work in desk top publishing. Of course, all of this can take time, effort and patience when utilizing all of the packages together. If nothing else, it sure gives one a greater appreciation for graphics as they are used today in desk top publishing. IT'S ON THERE by George author George Neff, Sr. (CLEVEATARI NEWSLETTER, Issue #101, March 1990) Each month a file from the "TCP" BBS will be highlighted. These programs can be yours free just for calling and registering to use the bulletin board. The modem number is (216)-228-7335. The times listed are for 1200 baud so if you are using 300 baud the time will be about four times longer and if you are using 2400 baud they will be one-half as long to download. These programs might not have been checked yet so if you have any trouble with the file let me know and I will try it. If I can not get it to work I will get a hold of the one who up loaded it and either find out what is wrong or get a working copy loaded to replace it. To conserve space on the board most files have been arced in one form or another, if you have problems extracting them see some one at the meeting and they should be able to help you or get someone who does know how. In the ST download-sig section  ST GAMES: again, is a ShareWare program called WHEEL2_0.ARC. This is a GFA Basic game that is fashoned after the tv program as the name implies. It is well done and worth the asking. There are editor programs to make your own puzzles included in the arc file. There are 839 blocks and will take 15 min. to download. Remember the REVOLUTION (tm) MULTISYNCH MONITORS COLOR AND HIGH RESOLUTION MONOCHROME DISPLAY FOR THE ATARI STs author Wm. H. Price (Originally downloaded from GEnie) (Printed CLEVATARI NEWSLETTER Mar & Apr 1990 in a two part series) COLOR BETTERS THE ST'S SC1224 Most multisynch monitors, but not all, will work with the ST's RGB output and vertical refresh rate. Advantages are operation in high resolution monochrome and both low and medium color using a single monitor. An additional advantage is the better color rendition with more differentiation in tonalities. Subtle shades are better represented than on the ST. With Sony color monitors, the colors are Kodachrome in quality -- rich and saturated. On the negative side, none of these color monitors will match the sharpness of the Atari SM124 monochrome monitor. This monitor, as with other monochromes, uses single pells or pixels to represent screen images. Color monitors must use three (Red, Green, and Blue) to form the same point on a screen. As a consequence, they cannot give the crispness and detail. THE CRITICAL TEST -- MONOCHROME SHARPNESS If you use monochrome most of the time, as many do with Spectre Macintosh emulation, the major question is whether or not a softer and coarser monochrome display on a color monitor is acceptable for continuous use. It doesn't make sense or cents to buy one of the lower priced multisynch monitors as an economy measure just to obviate the need for two monitors where high resolution monochrome is important. And the purchase of a higher quality and higher priced monitor in the $600 to $650 range -- such as the Sony 1304 HG or NEC 3D may not make much economical sense either. However there are those who continue to have the desire for these types of monitors -- unfortunately, I am one. MONITOR SWITCH BOX -- ROLL YOUR OWN The following pages give pinouts and wiring diagrams for construction of a Monitor Switch Box so that a multisynch can be used in both color and monochrome with the ST's monitor output. The box is needed to ground the Monochrome Detect line from the ST and force it to boot in high resolution monochrome. It also switches from the ST's RGB color output to Monochrome Intensity output to drive the monitor. The pinouts for all three Sony monitors (1302, 1303, and 1304) are the same. NEC monitors such as the Multisynch and Multisynch II use the same pinouts. Where Sony and earlier NECs use DB-9 inputs, the new NEC 3D uses a DB-15 connector. The NEC pinouts shown are still valid for the 3D. A converter cable -- DB-9 to DB-15 supplied by NEC -- will give the proper interface. This converter is also availabe commercially as a one piece plug unit. Other monitors, such as the Mitsubishi Diamondscan, use different plugs. The Mitsubishi uses a DB-25 which is the same in pins and shell as an RS-232. The ST's output can be routed to these monitors with the proper pinouts and plug. The Monitor Switch Box can be wired for any monitor output configuration. If another monitor is used, a simple conversion plug is comercially available to reconfigure outputs if both monitors use DB-9 plugs. If plugs are different for two monitors, then wire a cable with the two different terminations. The least effort and highest cost approach is to buy a cable with one of the plugs already made up. If you are good with a soldering iron, then buy the connectors and makeup your own cables. The ST 13-pin DIN plug is not that easy to work with. The solder or rear side has pins just like the front, and soldering wires to these contacts is not a snap. ST monitor cables, with a DIN 13 male on one end and unterminated on the other, are available from two or three sources. Try Best Electronics or Practical Solutions. A 4-pole, double throw switch (On-On) will be required for the Box. Also fit the Box with an RCA jack if you want sound routed to a stereo or self amplified speaker like those available from Radio Shack. If you have Tweety Board, this will not be needed. MARKET FAILURE OF SWITCH BOXES There have been several attempts to market these monitor switch boxes, and all but the most recent have not met with success. The first reason is high price. The first box produced was overpriced in the $200 range. The second reason is differences in pinouts and plug configurations for the variety of monitor inputs. There is no standard. The third reason for lack of success is the small ST market for alternative multisynch monitors. Making your own box for $35 or less in parts will give you an opportunity to try out several monitors at a dealer and select the one that is most acceptable for high resolution monochrome display. But a problem is that most dealers don't have the more expensive monitors broken out for display, and you may not be able to give one a try. Be persistant. Ask the dealer if he can recommend a customer that has a monitor you are interested in. But by all means, try before you buy to insure that the display meets with your satisfaction. Don't take the word of others because each has different levels of acceptability. MULTISYNCH MONITOR PERFORMANCE I have tried the homebrew Monitor Switch Box with the Sony 1303 and the NEC Multisync and Multisync II. The 1303 is not the quality of the 1302 which has a finer dot pitch. However, the color was excellent but the monochrome display was soft. The Sony 1302 has a .26mm dot pitch. This is a measure of the center-to-center distance between dots and is also an indicator of dot or pixel size. Until recently, the 1302 had the finest dot pitch of any color monitor on the market. And dot pitch is a better indicator of sharpeness than horizontal and vertical lines of resolution. The lines are also a function of screen display size; so don't be mislead by more lines resolution. It simply might correspond to a larger monitor display size. And as the monitor size increases, the dots are made larger and render a less sharp display. But Sony is less than forthcoming in its specifications for the 1302. While touting the .26mm dot pitch, they don't publish the fact that this applies to horizontal spacing only. The vertical spacing is different, perhaps .32mm which is nothing to shout about. As a consequence, you may see black horizontal lines that separate the color display lines. They are not dramatically obtrusive, but they are there. On the plus side, the Sony's have that superb Kodachrome color that is richly saturated. The blacks are black, and the background in monochrome is absolutely paper white. The 1302 is satisfactory for ST monochrome use. This model is being superseded by the new 1304 HG that has a .25mm dot pitch. The specifications on this new monitor closely match those of the Apple Color Monitor for the Mac II. This monitor is made by Sony to Apple's specifications, but it is not multisynch. I use one on a Mac II and it is excellent in both monochrome and color. Because of the closeness in specifications -- the only two monitors available with a .25mm dot pitch -- I strongly suspicion that they are the same. Sony has simply adapted the Apple version for multisynch use. And if I were to place my money on a monitor that would be highly acceptable for monochrome display with the ST (sight unseen in an actual test), it would be the Sony 1304 HG. When viewed in color on an IBM PC, the dots appeared extremely fine and it appears that the .25 pitch holds true for both vertical and horizontal. The 1303 is not as good as the 1302 or 1304. However it did give a good monochrome display that was similar in size to the ST's color display in medium resolution. Although good, it does not come close to matching quality of the SM124. Since I spend at least 60 percent or more of my time in Spectre/Macintosh operation, I felt that this was not acceptable for my requirements. When switching from color to monochrome, the screen picture sizes must be readjusted. When the color picture fills out the screen, the monochrome picture will be half screen size until it is adjusted. The Sony controls are in the rear, making them very inconvenient for this operation. The NEC and NEC II have their controls on the front. When making adjustments, insure that horizontal positioning is correct. When first tested, the NEC seemed to have ghosting with the character display. However this was because the screen had wrapped around and required proper positioning. The NEC display was also good. But it was not the equal of Sony in color -- more pastel and less saturated. Both the Sony 1304 and NEC 3D now have automatic screen sizing when displays are changed; so this should eliminate annoying adjustments. Additionally, both are improved over earlier models. Both would perhaps make acceptable choices for monochrome use on the ST. But I would still think that the Sony 1304 would win by more than a hair if it is anything like the Apple Macintosh monitor. Perhaps a dealer will break one out for testing when they become more plentiful and prices drop. Sony 1304s are discounted for around $645, and 1302s for $575. NEC 3Ds are lower priced at $585. The Mitsubishi Diamond scan can be found at $499 and sometimes lower. If the 16" Nano FlexScan is a true multisynch, those who want everything can get it for just under $900. The following should get you started on a switch box so that you can perform your own acceptance testing. I have not tried a Princeton Graphics or Mitsubishi Diamondscan since I felt that their displays with the IBM PC were not the match of the Sony or NEC. It wasn't worth the money or effort for such a change, and a promise was made a long time ago not to compromise and throw money at something you wouldn't be satisfied with. Climbing out of that hole is too costly, and I have paid this price in both camera and stereo equipment -- but never again.

ATARI PLANETARIUM - A NIGHT WITH THE STARS author Randy Hahn (CLEVATARI NEWSLETTER, Issue #101, March 1990) About two years ago, I remember a demonstration of the Atari Planetarium at the Natural History Museum by Bruce Frumker. It was demonstrated on an Atari 8-Bit machine. Since that time, Atari Planetarium was translated to ST format by Atari so anything you see in the demo can equally apply both to the 8-Bit and the ST world alike. At the time, it seemed like a nice program, but I thought that you would have to be a fanatic about stars to really use the program. Was I wrong! This program is something which can enlighten both young and old alike and is really an educational tool in which to learn about the solar system. I had the pleasure of demonstrating the program to an elementary school class (who subsequently went to the Cleveland Planetarium at the Natural History Museum) and they were intrigued by the what the program could show them. The program could even do things which the real Planetarium couldn't. Yet I felt like I only touched the "tip of the iceberg" with the demonstration. Atari Planetarium shows the computed positions of over 3500 stars, all 88 constellations all the planets in our solar system as well as more than 300 deep sky objects such as other galaxies, Haley's Comet and other star clusters. It also has a special information function built in which identifies verbally the objects as you point at them. The program allows you to travel in time approximately 10,000 years forward or back as well as witness any event both past and future from almost any latitude or longitude on the earth's surface. The program is so easy to use that a novice can learn it in one sitting and an expert can be enthralled by the versatility and vastness of the programs abilities. Having been a navigator in the Navy, where I used the stars to navigate across the ocean, I had a special appreciation for what the program is actually doing in all of its data manipulation and calculations behind the scenes. I only wish I had such a tool when I was aboard ship in the navy. There is a tremendous find function which can instantaneously find any of the constellations or planets. All of the functions are mouse accessible from a group of pull-down menus. Many of the functions can also be accessed by some keyboard key combination. Any sky image can be printed or saved at will. You can also speed up or slow down the clock which animates the various celestial events as they occur. The documentation is a book of over 150 pages which contains examples, historical events and an overall primer on the stars. It alone is worth the money I paid. I was especially enlightened by the discussions on Chronology, History and Archeology as they pertained to the stars and navigation. The "Guided Tour of the Universe"is extremely interesting and helpful in the learning process. The book also contained discussions on the Star of Bethlehem, Haley's Comet, the stars and how they were used by the Romans, Greeks and Egyptians and even a discussion of the possibility of extraterrestrial life. The discussions in the book are so well written that they stimulate the thought process as well as provide an interesting gateway to the stars. At the end of the book are tables, technical notes, future celestial events (including times and places), mathematical conversions, a glossary of terms and an index to help you find your way. This along with the bibliography of 59 entries has to give you some idea of the research that went into this baby. One of the real beauty's of the program is being able to explore the sky even on cloudy and overcast or stormy nights from the confines of my computer terminal. The program is designed for anyone who looks at the sky and wonders what a particular object might be. You definitely don't have to be an astronomer to enjoy it.
