The aim was to keep the program short and powerful. ~}Until now Atari DOS 2 seemed to be the most convienient DOS to use but was only capable of single density and was memory in}efficient. Other double density DOS's are available but they use heaps of memory or are extremely slow because you need to l}oad a file to perform each function.SuperDOS combines many functions (and more) from some of these giant DOS's into an ea}sy to use, menu driven DOS needing slightly more memory than Atari DOS 2.0S but using seven sectors less on the disk and the}refore taking less time to load. With 64K RAM XL/XE and all SUPERRAM models, DUP is hidden in RAM under the OS or in the r}amdisk and available imediately with NO loss of the resident program. The 256K SuperRAM ramdisk, plus 130XE, Axlon, Bucholt}z, Newell, Peterson and RAMbo ramdisks are supported.Features 1. SuperDOS for Atari 400/800/600XL/800XL/65XE/130XE comput}ers, Atari 810, 1050, XF551 and compatible disk drives. 2. Single, Enhanced and Double density plus double sided, doubl}e density operation. 3. Handles up to 4 disk drives plus a ramdisk plus up to 8 concurrent files. 4. Auto density enabl}es SuperDos to automatically configure to the density of the disk in the drive. 5. With auto density you can copy files} from single to double density (or vice versa) with only one drive. 6. RESTORE deleted or open files, either from SDUP }menu or BASIC with XIO commands. 7. Use upper, lower case, inverse characters or numbers even as the first char of} a filename. 8. Short SYS files allows maximum use of disk space and memory. 9. Variable XL/XE key delay and repeat rate.1}0. Ramdisks: SuperRAM & Peterson with 256K, 130XE with 64K or Axlon, Bucholtz, Newell, or RAMbo with 180K. Enables insta}nt loading of files.11. Autoload all files with "RAM" filename extenders from drive one to the ramdisk during boot proc}ess.12. With SuperRAM or 64K RAM, SDUP is available the instant you type DOS and the resident program is saved. No MEM.}SAV waiting.13. Use single keystrokes to list drrectory or select items.14. Copy to or from casstette "C:" device using lon}g or short IRG. Copy all SYS files except DOS.SYS using wildcards.15. A verification prompt message gives you a chance }to change your mind about copying a file.16. Write DOS.SYS file only or format a disk with skewed sectors using Sup}erMAX, US Doubler or Atari XF551.17. Copy sectors and display bad sector numbers. Copy only the used sectors.18. Option to }format destination disk during disk copy. It formats in the same density as the source disk.19. Enter sector numbers in} hex or decimal. Default is hex use # for decimal. eg #370.20. Write with or without verify. Toggled from SDUP menu.21.} Drive status (density, sides) is displayed on top of the screen above SDUP menu.22. Concise menu with plenty of room f}or directory listings. There are 2 columns on dirs.23. Annoying Atari 4 line scroll removed.24. A red screen border in}dicates next operation may write to the disk. Purple for format.25. A red or green screen border to indicate write or r}ead in next operation of copy file disk or sectors.26. A binary save that even saves carts.27. A copy from DOS 3 using} 1 or 2 drives and wildcards.28. SuperBIN - a boot program to display a menu of file names and load and run the bin fil}e you choose.29. Display the conmfiguration block of drives. (not 810 or 1050)30. Trace and link data of files and patch ar}ound bad sectors.31. Option to display deleted or open filenames.32. Alter the number of open file or drive buffers from th}e AUX menu.33. Choice of resident or non-resident SDUP. Enables instant access to DOS menu on 400/800 or option to disa}ble the ramdisk.34. SUPERBAS - an AUTORUN.SYS file to display a menu of BASIC programs to load and run.35. I/O default}s to the ramdisk if one is available.36. Use ESCAPE when booting to format a ramdisk leaving all normal 130XE banks fre}e (requires 128K)THE VARIOUS DENSITIESThere are 4 standard disk formats used by SuperDos, Atari and Atari compatible dis}k drives.1. (S)INGLE - 720 sectors of 128 bytes. 810 format.2. (E)NHANCED - 1024 sectors of 128 bytes. 1050 format.3. (D)O}UBLE - 720 sectors of 256 bytes. SuperMax, Us Doubler, Happy format.4. (X)TENDED - 1024 sectors of 256 bytes. SuperRAM, 130X}E & Peterson ramdisks.5. (2) SIDES - 1440 sectors of 256 bytes. Atari XF551 format.LOADING SUPERDOSWorks the same wa}y as DOS 2 with these extra steps:1. During the boot process (after about 5 sectors) a test is made for SuperMAX or Ata}ri XF551 and the baud rate is adjusted.2. With 64K RAM XL/XE, the "SDUP.SYS" file is now loaded and hidden in the RAM un}der the OS or in the ramdisk.3. With SuperRAM, the 130XE or other ramdisk, the ramdisk is initialized (if ESC was presse}d the 1st 4 130XE banks are not used) and all files with the ".RAM" extention are copied to the ramdisk. Press BREAK t}o abort it.4. Continue as DOS 2. Load and run "AUTORUN.SYS" and pass control to cartridge or SDUP.SYS.WHAT HAPPENS WH}EN YOU TYPE DOSThe same thing happens no matter how much RAM your Atari has.1. A check is made to see if "SDUP.SYS" is sti}ll intact in RAM under the OS OR in bank 2 of the SuperRAM ramdisk OR it is in the resident program area. If it is th}en the DOS menu appears instantly.2. If SDUP.SYS in not in RAM then it is loaded from drive 1.3. If the disk in drive 1 doe}s not have SDUP you are returned to the calling program.GUIDE TO THE SUPERDOS MENUAt the top of screen you'll see the} status line. It indicates which drives are available and the density of each of them.At the prompt "SELECT ITEM OR RETURN}" the following commands are available. Only one keystroke is required.#1-4 List the directory of drive 1 to 4.}#5-8 List the contents of the ramdisk.A. DIRECTORY Also may be used with the ramdisk. The directory listing} may have some info you have not seen before."- DELETED .TXT 014" Deleted file"? OPEN .TXT 000" File opened but} never closed." 011" This file uses sectors beyond 720 and  only available in Enhanced density or}  2 sided.Use the /N option to skip OPEN and DELETED files (eg "D1:*.*/N,E:")B. CARTRIDGE XL/XE users ha}ve the option of enabling or disabling BASIC.C. COPY FILE Copy AND duplicate file. A red or green border will indicate }the next read/write operation.1. You may enter one OR two filenames seperated by a comma. a. Enter one filename for} one drive copy. eg "D:TEST" b. Enter two filenames for two drive copy.  eg "D1:TEST,2:TEST" c. Enter two f}ilenames (one or two drive copy) to APPEND  or RENAME while copying.2. Auto-density configures SUPERDOS and the dr}ive to the  density of the DISK in the drive. You can then copy between densities with one drive.3. The cassette} "C:" device may also be used. The default is short IRG (Inter Record Gap). This is the same as BASIC's CLOAD and C}SAVE. To specify long IRG use /L. eg "D:TEST,C:/L" copies the file from disk to cassette using long IRG.4. Wildc}ards may be used in both source and destination filenames. 5. All "SYS" files except "DOS.SYS" may be copied using} wildcards.6. The wildcard mode displays the verification prompt "TYPE  "Y" TO COPY - D1:TEST". Press "Y" to copy t}he file or any other key to go onto the next file.7. To use the wildcard mode to copy all the matching files  af}ter the first "Y" response enter the /N option in the destination filename. eg "D:*,2:*/N"8. To use the wildcard with}out any verification prompts enter the /N option in both filenames. eg "D:*/N,2:*/N"D. DELETE Same as DOS 2E.} RENAME You can rename using wildcards. "*.DAT,*.BYT" renames all thefiles with the extender "DAT" to "BYT". However}, you still need to be careful not to specify a file that already exists.F. LOCK Same as DOS 2G. UNLOCK }Same as DOS 2H. WRITE DOS You can write both "DOS.SYS" and "SDUP.SYS" or "DOS.SYS"only. Just follow the prompts.I. }FORMAT You may select the formatting density: Single, Enhanced, Double, Extended or 2 sides. Follow the prompts.1}. You can only format with skewed sectors in Double or 2 sides with the Atari XF551 or in Single or Double density }if your drive is fitted with SuperMax or the US Doubler, thus allowing extremely fast read/write speeds.2. The Enhanc}ed density format is compatible with DOS 2.5  but with 1011 free sectors. (Dos 2.5 doesn't use sect 720)3. The 2 side}s format is upwardly compatible with standard  DOUBLE density. (ie the files and free sectors on side 2  are invisi}ble to single sided drives.)4. You may format the ramdisk, as you would a floppy disk,  but memory requirements limit} the type of format. If you  pressed ESC during the boot process then you must reboot  if you want to recover the r}eserved 64K. See NEW DISK  COMMANDS for ramdisk formatting details.J. DUP. DISK Copy disk or sectors. Unlike DOS 2 }this option copies ALL theused sectors of a disk. It even copies boot disks. If all the bytes of a sector are the same }value then the sector is not copied.1. If no sectors are specified then the entire disk is copied and you have the} option of formatting the destination disk. The formatting density is taken from the source.2. If sector numbers are }entered then only that range of sectors is copied.3. If any disk erros are encounted you'll see the message  "BA}D SECTOR - XXX "Y" TO RETRY". A "Y" will retry as many times as you want or any other key will continue with the ne}xt sector.4. You may copy disk or sectors to or from the ramdisk  provided your ramdisk can match the density of the }disk.5. You may enter sector numbers in hex or decimal. (Default is hex, use "#" to specify decimal. eg #370)6. A }red or green border indicates the next read/write.K. BIN. SAVE Same as DOS 2. Memory addresses may be decimal. eg #20788}. You can even save roms without error.L. BIN. LOAD Same as DOS2M. GO ADDRESS Memory addresses may also be decima}l. 1. If you type RETURN only, you can run at the address of a previously loaded binary file. Note: the run address i}s  destroyed when the program area is destroyed.N. RESTORE or "undelete" restores OPEN or DELETED files. You'll s}ee theprompt "RESTORE FILE SPEC?"Type in the name of an open or deleted file (wildcards maybe used). These files are} indicated by - or ? in the dirlist. CAUTION: A directory list may show a used, deleted and/or open file with the same }name. If you RESTORE this fileyou may finish with two files with the same name. To avoid this RENAME the file currently} in use then RESTORE. If youhave written to the disk since deleting a file then RESTOREmay encounter errors. If so, the}n only those sectors BEFOREthe error will be restored and you'll see an error message.If the first sector does not belo}ng to the file then the filewill remain deleted.O. VERIFY Toggles the SIO write command between write with verify }"W"and write without verify "P".THE AUX.SYS FILEThis file has some seldom used commands and is loaded using the "L" co}mmandfrom the SDUP menu.#. LIST DIRECTORY Type 1 thru 8 to list the directory of drives 1 to 8. P. INITIALIZE DOS Afte}r you have altered the number of open files or drive buffers or toggled the resident SDUP option you will need to i}nitialize DOS. This will destroy any BASIC programs.Q. COPY FROM DOS 3 Copy files from an Atari DOS 3 disk to a DOS 2 disk.} It is used exactly as the C. COPY FILE command.R. WRITE SUPERBIN For a description of SUPERBIN see WHAT IS SUPERBIN?} Follow the prompts. 1. SUPERBIN may not work with every BINARY LOAD file because it requires some memory. }SUPERBIN errors cause a cold start. 2. The correct density will be selected for you. You can  delete "DO}S.SYS" and "SDUP.SYS" as they are not used. 3. CAUTION: The SUPERBIN menu displays only 24 files and, as there a}re only three directory sectors allocated, writting more than 24 files may overwrite existing files.S. CONF}IG. BLOCK The config block is a set of 12 bytes in the disk control microprocessors memory inside the disk drive. This}  command merely displays this information to the screen. Note: Atari 810 and 1050 drives do not have config blocks} (unless upgraded) and sending this command produces an SIO error.T. TRACE AND PATCH Use this command to PATCH ar}ound bad sectors (ie SIO errors only) on a disk. You may have noticed DELETE does not delete a file with bad sector}s. (DOS 2 doesn't either). TRACE AND PATCH will trace a file until it  encounters a bad sector and then look look }for the next  sector on the disk belonging to that file. It then points  (alters sector link data) the sectore befo}re the bad  sector to the next matching sector and decrements the  number of sectors belonging to that file. If the}re are bad  sectors in a file then you'll loose the data in the bad  sectors but you can access the remaining data }or delete  the entire file.U. XL/XE KEY RATE Alter the key delay and repeat rates for the XL/XE OS  only. To alt}er the rates in DOS on the disk, you'll need to write the DOS files.V. FILE BUFFERS Alter the number of open file b}uffers. You need one file buffer for each concurrently open file. To alter the file  buffers in DOS on the disk, yo}u'll need to write the DOS  files.W. DRIVE BUFFERS Alter the number of drive buffers. You need one for each  di}sk drive. To alter the drive buffers in DOS on the disk,  you'll need to write the DOS files.X. RAMDISK ENABLE Toggle}s the ramdisk. "1" indicates that during the boot process the ramdisk is to be initialized.Y. RESIDENT SDUP Toggles }between the resident and non-resident SDUP. 1. The value of the OS variable MEMLO ($2E7) is altered so the user }program will be destroyed.  2. With less than 64K RAM a resident SDUP ensures that your user program is always s}afe and DOS appears instantly. Unfortunately this also means less memory. 3. With SUPERRAM or 64K (or more) SDUP} is always loaded during the boot process and hidden under the OS or in the ramdisk. With a resident SDUP you} can reserve  memory from the DOS buffers (usual MEMLO) to the end of  SDUP for your own use (see Memory Map }for addresses). This could be usful for co-resident machine language  and BASIC programs.Z.

It is used to LOAD and RU}N games or any other program that will loadusing the "L. BIN. LOAD" option of the SDUP menu. You won't need any "SYS" files } on a Superbin disk and only three directory sectors (24 files) are allowed. You will fill the rest of the disk with your bi }nary load files. (They must have a RUN address). When you boot a Superbin disk it willdisplay a menu of files on the disk.  }You make your selection by pressing theappropriate key and the file is loaded and exectued for you.WHAT IS SUPERBAS?Supe }rbas displays a menu of BASIC programs and you can select a program toLOAD and RUN. To create a Superbas disk:1. Format a d }isk and write DOS.SYS only.2. Copy the SBAS.SYS from your SuperDOS master disk and rename the file to AUTORUN.SYS.3. Cop}y your BASIC programs onto the disk.4. Rename the BASIC programs with exteners to filenames without extenders.5. Lock the p}rograms you wish to be displayed on the menu.ALLOCATION OF DRIVE AND FILE BUFFERSSuperdos always allocates buffers for do}uble density operation. It isinitally set for two drives and three concurrently open files. Use theAUX.SYS menu to alter Su}perdos to your own requirements. You'll need to writethe DOS files on the disk the keep the change. These options affect the}of memory you have available.SUPERDOS AND RAMDISKSIf you have extra memory for a ramdisk, the ramdisk will be initalized} usingthe maximum format available when you load Superdos. You can keep the first64K free (ie the normal 130XE RAM) by pres}sing ESC during the boot process.If you don't have enough RAM this may result in no ramdisk but allows you torun programs t}hat require this RAM. The ramdisk is accessed using DOS and isassigned as drives 5 to 8. Some programs (eg AtariWriter) only} provide accessto drive one. To use these programs:1. Remove the disk in drive one and turn it off. You may now load and sa}ve but all IO is diverted to the ramdisk.2. Turn drive one on to use it again.MEMORY MAP OF SUPERDOS Address } Contents 0000-05FF RAM Operating System 0600-06FF RAM Unused 0700-1CCD RAM Disk Operating System (File Manag}ement System) 1CCE-22CD* RAM Drive and File Buffers.
