No, you are not dreaming, here is the latest packer that Louis Roy wrote especially for you: DISK DISINTEGRATER DeLUXE V4.0 The original !! (nothing less...) D.D. DeLUXE is more than a packer, it is a totally new mean of communication. Effectively, when you will have discovered the new ideas included in this program as well as the power of the new features, you will never acccept again to use other DDD imitations, and you will only swear by D.D.DeLUXE, guaranteed! Louis Roy, the author of this program, has completely redesigned his packing algorythm. It packs more and faster! He also included a super fast and reliable checksum mechanism to validate the integrity of the compressed data. And Louis has designed this package thinking of the various types of users out there, from the faithfull ][+ users, all the way to the PC transporter //GS users of today, without forgetting Sysops, Hard disk and Ram disk users, etc.. Another significant built-in feature of the program is the capability offered to the packing user to compose, and permanently store in the packed file, an 11 line personnal message, and this, plus the built-in checksum and all the new features that you will soon discover, has resulted in a faster packer! As we said before, the world of modem telecommunication will never be the same again! ....................... D.D.DeLUXE AT A GLANCE: ....................... o Can pack 5.25, 3.5 800K and 3.5 1600K disks. o Compatible with all PRODOS devices in existance today, including Ram disks, hard disks, etc.. o A new feature that permit you to communicate with hundreds of people o have a copy commands that permit you to copy file from a directory to another. o have a optimize option to pack even more (only prodos disk) o have a clock on the main menu o Support up to 14 storage units connect to your Apple. o Will execute on Apple ][+, //e, //c and //GS. o Recognize, and utilizes your 80 columns cards (except on a ][+) o Packs more than ever. o Packs and unpacks faster. o PRODOS Hard disk compatible. o Window driven. o Keeps the name of the packer and the date of packing. o User friendly, less typing involved thru intelligent user interface. o Built-in checksum. o Supports all PRODOS commands directly from the program. o Built-in FORMAT command recognizing all PRODOS devices. o Keeps your configuration and personnal message between sessions. o Full error trapping mechanism. o Recognizes, and utilizes, any clocks you may have. o Built-in mini editor to edit your personal message. o Packs and unpacks with one or more devices. o Allows duplicate volumes on-line (contrary to COPY ][+). o Easy to use! o and more!! ....... HISTORY ....... Most of you have heard of the history of the famous DDD packer, but for the benefit of those that may not, we will recap the acomplishments of Louis Roy: 1983: Louis Roy, under the alias of DALTON, writes his first packer. Immediately this became a huge hit. It became THE de-facto standard in the modem world. What made this packer so special? Basically, a faster and more effecient packing algorythm and a few new ideas that were destined to become some of the most copied features of the day: the mean to compress a full disk of data into a single transferable file! This became the start of a revolution in the world of packers... From that day onwards, packers would never be the same again, thanks to DDD V1.0. 1984: He writes a new version, DDD V2.0. This version supported new utilities, but still was using the DDD V1.0 packing algorythm. The program became visually more attractive, and user friendly routines as well as a more intelligent user interface appeared, things such as a track status bar, built in size appearing in the packed title, etc... 1985: DDD V2.1 correcting a bug in V2.0. 1986: DDD V3.0. Louis wrote this new version of his now legendary packer, but decides not to release it. This version supported many of the features that you will now find in DDD V4.0. The personnal message, hard disk support, all appeared in that version. It was still using DOS 3.3. Why wasn't it released? Because Louis decided to stop programming for the Apple all together. Even with the new packer nearing completion, he decided to take a sabatical to put his life in perspective. The life of a hacker is an arduous one, sooner or later you must let go... This seemed to be the signal other hackers, with little immagination of their own, were looking for! From this moment on, we saw the appearance of new packers while keeping compatibility with DDD V2.1. Even now, most packers in use have blatently copied his algorythm. Sometimes one wonders if programming ability is not equivalent to copying abilities!. 1988: After his sabatical, Louis takes charge again by introducing Disk Disintegrater DeLuxe V4.0. The packing algorythm has been totally revamped into a faster, more powerful packer. Mark my words, this packer marks the dawn of a new era, and believe me, the shock waves will be felt all over the modem world, and probably, the same unimaginative people will copy it again. Make yourself a favor, use the original! As in other domains, the original has usually the upper hand on the copy! ............. COMPATIBILITY ............. A) D.D.DeLuxe is not compatible with the older algorythm of DDD V2.1 (and other compatible packers). Why? Keep reading, the reasons will become obvious... In any case, this packer will render all other obsolete! B) D.D.DeLuxe will execute bug free under the following computers: - Apple ][+ or compatible, with 64k - Apple //e, enhanced or not, with or without extended 80 column cards. - Apple //c, all models - Apple //GS C) Screen mode: o Apple ][+: The display will be in 40 columns mode and in upper case characters only, even if you have a compatible ][+ which supports lower case characters. The main reason being that even those compatible cannot display inverted lower case characters that DDD uses. If you have an 80 column card, D.D.DeLUXE will not use it, this is caused by the lack of standard in the ][+ 80 columns. Remember that you will have to boot DDD in 40 columns, any attempt to boot in 80 columns will result in garbage characters on your screen. o Apple //e without 80 columns card: You will see lower case characters, but obviously you will only get 40 columns of display. o Apple //e with 80 columns, Apple //c and Apple //GS: You will see both 80 columns and lower case characters. D) Disk format that D.D.DeLUXE can pack: - 5.25" floppy diskettes - 3.5" floppy diskettes with 800k capacity - 3.5" floppy diskettes with 1600k capacity (yes, we know, they don't exist....yet... but we can compact them!). E) Disk drives compatible with D.D.DeLUXE: - 5.25" disk drives - 3.5" 800k dives (this include Apple 3.5, Unidisk 3.5, Universal disk controller and all other 3.5 drives that are Apple compatible.) - 3.5" 1600k drives (not yet available, but Apple is rumoured to announce one for 1988). - All hard disks working under PRODOS (CMS, Siders, Profile, etc..) - All RAM cards that support a PRODOS RAM disk driver. - All Rom disks (such as the //GS Memory Saver). - PC transporter RAM disk. - PC transporter 5.25" PRODOS disk. F) PRODOS version: D.D.DeLUXE is compatible with PRODOS version 1.3 or higher. Do not use with older PRODOS revisions (it will not run). It's preferable to use V1.4 because V1.3 have minor bugs in it. G) Clock cards: D.D.DeLUXE will read your clock card as long as you have loaded its driver in the PRODOS boot (clock patch). D.D.DeLUXE is compatible with all standard PRODOS clock cards, with or without patch. D.D.DeLUXE will also work without a clock card, in which case you will be prompted for date/time input whenever required. ................................ WHAT YOU HAVE ON D.D.DeLUXE DISK ................................ The D.D.DeLUXE original disk have 2 sides. Following is a description of the various files on the disk: D.D.DELUXE.LOAD SYS file. To be used if you wish to start D.D.DELUXE.V4.0 directly from Applesoft Basic. D.D.DELUXE.V4.0 This is the main program of D.D.DeLUXE (application file). This file should never be renamed, if you use D.D.DELUXE.LOAD or if you use the Finder on a //gs. D.D.DELUXE.CONF This is the file where your personal configuration of D.D.DeLUXE (type BIN) will be stored. This file should never be renamed !! ICONS directory: FINDER.ICONS, FINDER.DATA and DDDELUXE.ICONS These files will only be useful for Apple //gs users. On the disk itself, these files are useless. Copy these files to the directory called ICONS of the Finder you are using. Your finder will then be able to load these files and will display the appropriate ICONS relative to D.D.DeLUXE files. A small surprise is waiting for you! (Note: you probably have FINDER.ICONS and FINDER.DATA on your disk, replace them by these new files). READ.ME.FIRST First text file to read when booting for the first time the D.D.DeLUXE disk (side 1). D.D.DELUXE.DOX1 TXT file. First part of the D.D.DeLUXE documentation. D.D.DELUXE.DOX2 TXT file. Last part of the D.D.DeLUXE documentation. DDDELUXE.BENCH TXT file. D.D.DeLUXE comparative benchmark, as done by Roger Richard (HA! HA!). DDDELUXE.ERRORS TXT file. List of error codes, and their significance, that you may encounter during the use of D.D.DeLUXE. BONUS.FILES TXT files. An extra from the author of D.D.DeLUXE, Louis Roy! Various interesting text files for your pleasure. ................................ WHY D.D.DeLUXE DOES NOT USE 128k ................................ D.D.DeLUXE works on any system with at least 64k (except on the original Apple ][). Maybe you are disapointed that the program does not make use of the full 128k, or more, memory of the //e, //c or //GS? There is a simple reason to this: it's faster that way! Even if the DDD's buffer is smaller by only using 64k of the available memory, resulting in increased disk access, it's still faster! This is caused by the peculiar architecture of the Apple bus. The Apple can only access 64k of memory at the same time, all subsequent 64k of memory are used as a switched memory bank. Basically, this demands a substantial amount of memory moves. In his beta version, Louis was using bank switched memory, but after a few bench marks, he noticed that the increased memory handling capability resulted in decreased performance. So he removed it. Statistically speaking, 98% of ther Apple systems in use have more than one disk drive, so this will not cause a problem to the majority of the users. Those that only have a disk drive are left with the alternative of using a ram disk, acquiring a secondary disk drive, or swap disks! (check the copy command for further instructions on how to use ram disks when packing and unpacking). ............... NOTE ON RAMDISK ............... If you have a configured ram disk with 800k, D.D.DeLUXE will treat it as a 3.5" 800k drive. The same rule applies with ram disks of 1600k. It will so be possible to you to unpack DDD files of 800k and 1600k onto ramdisks instead of the usual 3.5" disks. ...... CLOCKS ...... If your Apple has a clock card, D.D.DeLUXE will display the current date and time in a little window at the bottom left of your screen of the main menu. ......... RESET KEY ......... As in other Apple programs, never press the RESET button while D.D. DeLUXE accesses your disk. This may prove to be hazardous to the life of your disk! However, as long as D.D.DeLUXE is not accessing the drives, it will be safe to press reset, you will then be transported back to the main menu. ....... ESC KEY ....... At any stage during the program, you can go back to the main menu by pressing the ESC key. No matter where you are, no matter what you are doing, you can always ESCape back to the main menu! .......................... DISK ACCESS ERROR TRAPPING .......................... Anywhere and at any time, D.D.DeLUXE always utilizes the same error trapping routine. This routine is activated automatically whenever you get an error while D.D.DeLUXE is accessing the disk. In the eventuallity of such an error occuring, D.D.DeLUXE will tell you the appropriate PRODOS error code, in hexadecimal, in a little window at the top of your screen. Just refer to the standard PRODOS error codes (or the PRODOS error charts in a file on your D.D.DeLUXE disk) to find out the cause of the error and select an appropriate course of action. In an error situation, the program will suggest that you press a key if you wish to retry the same operation again. It may give you the same error again, but if you corrected the problem in the meantime, it will work. This feature will prove useful whenever you leave your disk drive open for example... ............................. WHAT'S THE PERSONNAL MESSAGE? ............................. The personnal message is a very powerful and useful feature, maybe the impact of this feature escapes you right now, but as you will soon find out, you will not want to pack without this option! Every time you will pack a disk, D.D.DeLUXE will compress and insert in the resulting DDD file your personnal message along with your name and the date you packed the file. When another person will de-compress your DDD file, D.D.DeLUXE will display automatically on the screen your personnal message, your name and the date packed. Can't you already sense the obvious advantages of such a feature? What could you write in that message? In reality, just about anything that you feel you would want other people to see, things such as documentation, special hints, even a classified ad! Let's say you have a modem to sell, etc.. You may even be able to reach somebody that you ignore his telephone number, even his address, the possibilities are endless! .................... WHAT'S THE MENU LINE .................... The menu line is edited at the same time as your personnal message. As the user unpacks the DDD file, at the very start of the unpack, your personal message will be displayed. But the menu line will only be displayed at the end of the unpack, providing that no errors were detected. This menu line will appear in the user's main menu as long as he will work with D.D.DeLUXE, or until the next unpack. What you will do with this menu line is only bound to your imagination, for example, you could use it as publicity for your favorite BBS, as this line will remain in permanennce on the screen of the unpacking user as long as he uses D.D.DeLUXE (or until the next unpack), or why not use it to pass on proverbs, I'm sure that already ideas are popping in your head. Take note that the menu line stay on the main menu screen even if the user use the option "View DDD file informations" (in PRODODS COMMANDS). ................................................... D.D.DeLUXE PRODOS FILE TYPE and DISK IDENTIFICATION ................................................... When you are packing, D.D.DeLUXE uses the PRODOS type $DD (short for Disintegraterr DeLuxe) to store your DDD file, no matter if you used 5.25, 3.5, 800k or 1600k. As of now, this file type has not been used by any other Apple software programs. When you will catalog such a directory with D.D.DeLUXE, these file types will appear as "DDD", but if you use other software programs to catalog such disks, they will appear as "$DD". This will facilitate the identification of DDD files. How will you know what type of medium is to be used during the unpacking operation? This is made quite simple, just look at the file name! D.D.DeLUXE utilizes suffixes to differentiate the various mediums: .A ---> 5.25 floppy .B ---> 3.5 800k disk .C ---> 3.5 1600k disk ............... HORIZONTAL MENU ............... At certain occasions, D.D.DeLUXE will ask you to choose certain options with the horizontal menu. In this case, just use the left and right arrows ( -> and <- ) to choose the option you desire, then press Return to accept it. ...................... NOTE ON DIRECTORY SIZE ...................... D.D.DeLUXE can catalog any PRODOS directory that contains a maximum of 600 files. Note that the limit applies to each directory, you may have thousands of files on your disk, but in any given directory (or sub-directory), D.D.DeLUXE cannot catalog more than 600 files. In the rare eventuallity of this happening, you will get the message "DIRECTORY TOO LARGE", in which case you should consider splitting that directory into smaller sub-directories. But in reality, we all know that nobody would have this problem since we all know what problem having such huge directories will bring. One final note, if you use a RAM disk driver, this limit will perhaps be lower, but then again, nobody should be affected. .................. EDITOR CONTROL KEY .................. Every time that D.D.DeLUXE will ask you to type anything, you will automatically have access to the following editing keys: -> : move cursor right in sentence <- : move cursor left in sentence DEL : delete character at left of cursor CTRL-D : delete character at cursor TAB or CTRL-I : toggle insert mode on/off CTRL-F : put cursor at first character of the line CTRL-L : put cursor at last character of the line CLEAR or CTRL-X : Clear line RETURN : Accept line ..................................... D.D.DeLUXE STANDARD DIRECTORY COMMAND ..................................... Every time that you use the following options: PACK, UNPACK, PRODOS COMMANDS, OPTIMIZE, VIEW DDD FILE INFORMATIONS, SAVE MESSAGE and COPY COMMAND you will always have access to the following commands: The first window that D.D.DeLUXE will display will be a list of the on line PRODOS volumes as well as a list of all devices without a valid PRODOS volume in it. At this time, you can use the arrow keys to browse through that list and choose your preference by pressing the Return key. Just remember that you will only be allowed to choose a device that contains a valid PRODOS volume. Then D.D.DeLUXE will show you a second window containing the directory of the volume you chose previously. You will also indicate to you wether the catalog you are viewing is a FULL or PARTIAL catalog. You will see such information on the top line of the window. At the bottom of the window, you will see the volume name, total free blocks of the disk as well as the total block capacity of that disk. You then have, at least, the following options: a) Arrows: Right and down arrows: move down 1 line in directory Left and up arrows: move up 1 line in directory Open apple + down arrow: move down 7 lines in directory Open apple + up arrow: move up 7 lines in directory b) RETURN key: If you wish to catalog a subdirectory, position your scroll bar to the subdirectory and press Return, D.D.DeLUXE will give you a new catalog of that subdirectory. c) Key "1": Back 1 directory. If you are not at the volume directory and you are in a subdirectory, you can backtrack to the previous directory by pressing the number 1 key. d) Key "2": Full and Partial catalog toggle switch. By pressing the number 2 key, you will activate a toggle between the full and partial catalog mode. In a full catalog, D.D.DeLUXE will display all files present in the working directory, in a partial directory, D.D.DeLUXE will only display the sub-directories and the files of type $DD (or DDD). This option will allow you to quickly zero in on such type of files. e) Key "3": Volume window. By pressing this key, D.D.DeLUXE will give you back the volume window of all on-line volumes on your Apple. Of course, if you inserted or removed volumes since the last time, D.D.DeLUXE will present you with an up to date picture of these volumes. Note that if your directory is empty, D.D.DeLUXE will display "No Entry". If you are in mode "full" and D.D.DeLUXE will display that message, then you have no files whatsoever in your directory, however, if you were in "partial" mode, then this message will indicate that you have no sub-directory or DDD files in the working volume. You may still have other types of file in this directory, to verify, just go in "full" mode by pressing "2" key. ....................... HOW TO START D.D.DeLUXE ....................... Before starting D.D.DeLUXE, if you have a clock card, you should evidently load its driver to patch PRODOS, if it hasn't been done already. Furthermore, if you also want to utilize your Ram card, you should also load its driver. Note that no diver are neccessary for /RAM5 on the //GS or the standard /RAM on the //c or //e. And don't forget either that you must use PRODOS 1.3 or higher. Do not rename the following files, as they are used by D.D.DeLUXE and you may create unneccessary problems: "D.D.DELUXE.V4.0" "D.D.DELUXE.LOAD" "D.D.DELUXE.CONF" You must have the configuration file "D.D.DELUXE.CONF" residing in the same directory as "D.D.DELUXE.V4.0", so that D.D.DeLUXE can load this configuration. If the configuration file is not found, then D.D.DeLUXE will configure itself with default parameters. If you are using a //GS, you can start D.D.DeLUXE directly from the Finder by executing the main module: D.D.DELUXE.V4.0. You will not need to execute the D.D.DELUXE.LOAD if you use the Finder or the PRODOS dispatcher (PRODOS BYE or QUIT commands). If you start D.D.DeLUXE from Applesoft basic, then you must start D.D.DELUXE.LOAD first, this binary file will load the main program D.D.DELUXE.V4.0 in resident memory. This procedure is neccessary due to the size of the routine and this could cause a conflict with the BASIC.SYSTEM in memory if you wished to start directly from basic. If you have an Apple ][+, you must start D.D.DeLUXE from 40 columns, if you have an 80 column card, you must refrain from using it. Once loaded. D.D.DeLUXE will show you a banner page, at this stage, you may elect to press the letter A to read the "About D.D.DeLuxe" for the program, pressing any other key will go directly to the main menu. Voila! You are now ready to utilize D.D.DeLUXE. If this is the first time ever you used D.D.DeLUXE, you will probably elect to go to option #8 and configure your personnal version of D.D.DeLUXE, if you need help with this option, read the documentation on the CONFIGURE option. ......... MAIN MENU ......... First, let's review the list of commands that will be documented in the following paragraphs and are available from the main menu: [1] Pack disk [2] Unpack disk [3] Prodos commands [4] Edit my message [5] View last DDD info [6] Optimize Prodos disk [7] Format Prodos disk [8] Checksum disk [9] Configure [0] Quit You can choose one of the options directly by pressing its appropriate number or browse through the choices with one of the "browse" keys: Space bar, right and down arrow: down one line left and up arrow: one line Return: accept option selected ......... PACK DISK ......... This option will allow you to compress a whole disk (5.25, 3.5 800k or 3.5 1600k) into a single file. Here is how to proceed: 1) D.D.DeLUXE will ask you to select the location of the disk you wish to pack. D.D.DeLUXE will show you the inventory window of all the disk 5.25, 3.5 800k and 3.5 1600k allowable on your system. Using the arrow keys, choose the location of your original medium and press return. It is not neccessary that you insert your original disk at this time. You could do but you could also wait unto until D.D.DeLUXE asks you for it. If you are using an Apple //gs and you wished to pack a 3.5" disk, it would be preferable to insert the source disk prior to press RETURN in step #2. 2) The next step will be to type the name of the file you wish to assign to your PACKED DDD file, you are allowed a maximum of 13 characters, either in upper or lower case. Note that D.D.DeLUXE will always append a suffix to your selected name, this suffix will identify the medium to be used to unpack: .A ---> 5.25" floppy .B ---> 3.5" 800k disk .C ---> 3.5" 1600k disk Apple //gs user: Please note that if you chose to pack a 3.5 disk and that you have inserted the disk to be packed prior to start step #2, D.D.DeLUXE will default the file name to be used to the volume of the disk to be packed, if it is a PRODOS disk of course. You will then have the option of accepting it as is, to modify it, or to enter a different name, by pressing first the CTRL-X or CLEAR (clear line). Note: it's now time to insert your destination prodos disk where you want to save the DDD file. 3) If you are using an installed clock in your PRODOS, the D.D.DeLUXE will not ask your for the date, it will read it directly from the clock, however, if no clock was recognized, then D.D.DeLUXE will ask you to register the date, that date will be defaulted to the date you stored in the configure option, but you can always override it with today's date, or another, with the help of the following keys: right or up arrow: add 1 to current field (day, month or year) left or down arrow: subtract 1 from current field space bar: switch between fields (day, month or year) Return: accept the date 4) Now D.D.DeLUXE will show you the volume window. You can use the "STANDARD DIRECTORY COMMANDS" as mentionned previously to select the volume and directory where you wish to store your packed file. By default, D.D.DeLUXE will suggest you the first directory (the volume directory) in "partial mode". Note that if you haven't already inserted your target disk (the one where you want to store the DDD file) and that you are already at the volume window, you can still insert it right away and choose, with the scrollbar, the device where the disk resides (i.e. the slot and drive number), then press RETURN. Also note that if your target disk is not a PRODOS disk, or that it has never been formatted, D.D.DeLUXE will ask you wether or not you wish to format it (PRODOS format). If you decline, then D.D.DeLUXE will go back to the volume window (as you must absolutely choose a PRODOS directory to store your packed file). You must also make sure that there is sufficient space on the directory where you wish to store your packed file, otherwise you will end up having to redo the entire packing process. With experience, you should be able to estimate roughly the number of PRODOS blocks required to pack a disk. 5) Finally, D.D.DeLUXE can start packing! Check this: a) 1 drive operation: If the device you chose to pack your disk is the same as the device where your packed file will be stored, then D.D.DeLUXE will only use 1 drive to pack your disk. Get ready to do a lot of disk swapping! D.D.DeLUXE will ask you to alternatively insert your original disk and your destination disk. Don't make a mistake, because D.D.DeLUXE will not verify that this is indeed the original disk or the target disk (it would slow down the packing process). It would be a prudent decision to put a "write protect tab" on your original disk, just in case... The consequences could be that you damage your original disk. b) 2 devices operation: If your source and destination disks do not reside on the same device, then D.D.DeLUXE will assume that you are packing using 2 different devices, will ask you to insert both the disks to be used at their respective selected locations and start packing by pressing a key! c) Information displayed: D.D.DeLUXE will display the following five parameters: -> "DDD status" : Will tell you what DDD is doing -> "Block #" : the block number that DDD is currently loading in memory to compress it. -> "Total block": The total number of blocks to be compressed -> "Checksum8" : Since DDD loads 8 blocks of data at the same time to compress them, the checksum8 is the cumulative checksum of these 8 loaded blocks. -> "Total file block": This is the cumulative size, in block, of the packed file. d) When D.D.DeLUXE has finished, just press any key to return to the main menu. Voila! You have successfully packed your disk! NOTES: o D.D.DeLUXE will use PRODOS file type $DD for all files packed with D.D.DeLUXE. o D.D.DeLUXE will save in your packed file, your name, the date packed, your pesonnal message and your menu line and all checksums of the disk. o If you packed a 3.5" disk on a Apple //gs and if you use a APPLE 3.5 drive, and you do a 2 devices operations, D.D.DeLUXE will automatically eject your original disk from the drive. <>
