The HCI Dos posted sure looks a lot like SuperDos with a high-speed patch.

 

Real Happy's originally came with the "Warp Speed Dos." patch for unmodified Dos 2.0s. Later, Happy also licensed Dos XL from OSS and this was sold separately. IIRC, V2.42, which was another variant of 2.30.

I looks a lot like the one I down loaded from Pokeysoft web site..

http://pokeysoft.no/games/

 

http://pokeysoft.no/games/files/pokeysoft/Utility%20U130b.zip

 

And is also in the DOSFOLDER zip file I uploaded in a previous post.

 

Thanks for that information. I compared the DOS.SYS and SDUP.SYS from "my" version and the SuperDOS 4.3T version a post later and all files are nearly the same - just a few bytes different and the text strings. So I assume it´s the same thing at all.

Just compared dos 4.3 and 4.3T. T has extra code in ramdisk handler and other differences that don't make sense. Thus making it different from about $A10 on. No idea who did that.

Sdup and Tdup would be similar as expected. Will need to find the matching AUX.SYS file for 4.3T.

Looking at the code, T version sets the high bit of port A to output. Is there a ram expansion that uses this bit??

Probably TOMS for their drives. Or maybe Tygrys - Marek Bojarski for his Tygrys Turbo.
If not, I do not know.
I have somewhere SuperDOS 3.7T. Also do not know who did it and what for.

Here is SuperDOS 5.1 Manual

My opinion - It's VERY interesting DOS!

 

SUPERDOS

SuperDOS V5.1 was designed for the more advanced user who needs a DOS
with true double sided, double density operation. 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 inefficient. Other double density DOS's are available but
they use heaps of memory or are extremely slow because you need to load
a file to perform each function.

SuperDOS combines many functions (and more) from some of these giant
DOS's into an easy to use, menu driven DOS needing slightly more memory
than Atari DOS 2.0S but using seven sectors less on the disk and therefore
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 ramdisk and available
imediately with NO loss of the resident program. The 256K SuperRAM ramdisk,
plus 130XE, Axlon, Bucholtz, Newell, Peterson and RAMbo ramdisks are
supported.

Features
1. SuperDOS for Atari 400/800/600XL/800XL/65XE/130XE computers, Atari 810,
1050, XF551 and compatible disk drives.
2. Single, Enhanced and Double density plus double sided, double density
operation.
3. Handles up to 4 disk drives plus a ramdisk plus up to 8 concurrent files.
4. Auto density enables 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.
10. Ramdisks: SuperRAM & Peterson with 256K, 130XE with 64K or Axlon,
Bucholtz, Newell, or RAMbo with 180K. Enables instant loading of files.
11. Autoload all files with "RAM" filename extenders from drive one to the
ramdisk during boot process.
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 long 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
SuperMAX, 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 for directory listings. There are 2
columns on dirs.
23. Annoying Atari 4 line scroll removed.
24. A red screen border indicates next operation may write to the disk.
Purple for format.
25. A red or green screen border to indicate write or read 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 file you choose.
29. Display the conmfiguration block of drives. (not 810 or 1050)
30. Trace and link data of files and patch around bad sectors.
31. Option to display deleted or open filenames.
32. Alter the number of open file or drive buffers from the AUX menu.
33. Choice of resident or non-resident SDUP. Enables instant access to DOS
menu on 400/800 or option to disable the ramdisk.
34. SUPERBAS - an AUTORUN.SYS file to display a menu of BASIC programs to
load and run.
35. I/O defaults to the ramdisk if one is available.
36. Use ESCAPE when booting to format a ramdisk leaving all normal 130XE
banks free (requires 128K)


THE VARIOUS DENSITIES
There are 4 standard disk formats used by SuperDos, Atari and Atari
compatible disk drives.
1. (S)INGLE - 720 sectors of 128 bytes. 810 format.
2. (E)NHANCED - 1024 sectors of 128 bytes. 1050 format.
3. (D)OUBLE - 720 sectors of 256 bytes. SuperMax, Us Doubler, Happy format.
4. (X)TENDED - 1024 sectors of 256 bytes. SuperRAM, 130XE & Peterson
ramdisks.
5. (2) SIDES - 1440 sectors of 256 bytes. Atari XF551 format.


LOADING SUPERDOS
Works the same way as DOS 2 with these extra steps:

1. During the boot process (after about 5 sectors) a test is made for
SuperMAX or Atari 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 under the OS or in the ramdisk.
3. With SuperRAM, the 130XE or other ramdisk, the ramdisk is initialized
(if ESC was pressed the 1st 4 130XE banks are not used) and all files with
the ".RAM" extention are copied to the ramdisk.
Press BREAK to abort it.
4. Continue as DOS 2. Load and run "AUTORUN.SYS" and pass control to
cartridge or SDUP.SYS.


WHAT HAPPENS WHEN YOU TYPE DOS
The same thing happens no matter how much RAM your Atari has.

1. A check is made to see if "SDUP.SYS" is still 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 then 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 does not have SDUP you are returned to the calling
program.


GUIDE TO THE SUPERDOS MENU
At 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.
" <TWO .TXT>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 have 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 filenames (one or two drive copy) to APPEND
or RENAME while copying.
2. Auto-density configures SUPERDOS and the drive 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 CSAVE. To specify long IRG use /L.
eg "D:TEST,C:/L" copies the file from disk to cassette
using long IRG.
4. Wildcards 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 the file or any
other key to go onto the next file.
7. To use the wildcard mode to copy all the matching files
after the first "Y" response enter the /N option in the
destination filename. eg "D:*,2:*/N"
8. To use the wildcard without any verification prompts enter
the /N option in both filenames. eg "D:*/N,2:*/N"

D. DELETE Same as DOS 2

E. RENAME You can rename using wildcards. "*.DAT,*.BYT" renames all the
files 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 2

G. UNLOCK Same as DOS 2

H. 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 Enhanced density format is compatible with DOS 2.5
but with 1011 free sectors. (Dos 2.5 doesn't use sect 720)
3. The 2 sides format is upwardly compatible with standard
DOUBLE density. (ie the files and free sectors on side 2
are invisible 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 reserved 64K. See NEW DISK
COMMANDS for ramdisk formatting details.

J. DUP. DISK Copy disk or sectors. Unlike DOS 2 this option copies ALL the
used 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
"BAD SECTOR - XXX "Y" TO RETRY". A "Y" will retry as many
times as you want or any other key will continue with
the next 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 DOS2

M. GO ADDRESS Memory addresses may also be decimal.
1. If you type RETURN only, you can run at the address of a
previously loaded binary file. Note: the run address is
destroyed when the program area is destroyed.

N. RESTORE or "undelete" restores OPEN or DELETED files. You'll see the
prompt "RESTORE FILE SPEC?"
Type in the name of an open or deleted file (wildcards may
be used). These files are indicated by - or ? in the dir
list. CAUTION: A directory list may show a used, deleted
and/or open file with the same name. If you RESTORE this file
you may finish with two files with the same name. To avoid
this RENAME the file currently in use then RESTORE. If you
have written to the disk since deleting a file then RESTORE
may encounter errors. If so, then only those sectors BEFORE
the error will be restored and you'll see an error message.
If the first sector does not belong to the file then the file
will remain deleted.

O. VERIFY Toggles the SIO write command between write with verify "W"
and write without verify "P".


THE AUX.SYS FILE
This file has some seldom used commands and is loaded using the "L" command
from the SDUP menu.

#. LIST DIRECTORY Type 1 thru 8 to list the directory of drives 1 to 8.

P. INITIALIZE DOS After you have altered the number of open files or drive
buffers or toggled the resident SDUP option you will need
to initialize 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 "DOS.SYS" and "SDUP.SYS" as they are not used.
3. CAUTION: The SUPERBIN menu displays only 24 files and,
as there are only three directory sectors allocated,
writting more than 24 files may overwrite existing
files.

S. CONFIG. 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 around bad sectors (ie SIO
errors only) on a disk. You may have noticed DELETE does
not delete a file with bad sectors. (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 before the bad
sector to the next matching sector and decrements the
number of sectors belonging to that file. If there 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 alter the rates in DOS on the disk, you'll need
to write the DOS files.

V. FILE BUFFERS Alter the number of open file buffers. You need one file
buffer for each concurrently open file. To alter the file
buffers in DOS on the disk, you'll need to write the DOS
files.

W. DRIVE BUFFERS Alter the number of drive buffers. You need one for each
disk drive. To alter the drive buffers in DOS on the disk,
you'll need to write the DOS files.

X. RAMDISK ENABLE Toggles 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 safe 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. EXIT TO SDUP Returns you to the SDUP menu.

WHAT IS SUPERBIN?
Superbin is a binary loader that resides on the boot and directory sectors of
a disk. It is used to LOAD and RUN games or any other program that will load
using 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 binary load files.
(They must have a RUN address). When you boot a Superbin disk it will
display a menu of files on the disk. You make your selection by pressing the
appropriate key and the file is loaded and exectued for you.


WHAT IS SUPERBAS?
Superbas displays a menu of BASIC programs and you can select a program to
LOAD and RUN. To create a Superbas disk:
1. Format a disk and write DOS.SYS only.
2. Copy the SBAS.SYS from your SuperDOS master disk and rename the file
to AUTORUN.SYS.
3. Copy your BASIC programs onto the disk.
4. Rename the BASIC programs with exteners to filenames without extenders.
5. Lock the programs you wish to be displayed on the menu.


ALLOCATION OF DRIVE AND FILE BUFFERS
Superdos always allocates buffers for double density operation. It is
initally set for two drives and three concurrently open files. Use the
AUX.SYS menu to alter Superdos to your own requirements. You'll need to write
the DOS files on the disk the keep the change. These options affect the
of memory you have available.


SUPERDOS AND RAMDISKS
If you have extra memory for a ramdisk, the ramdisk will be initalized using
the maximum format available when you load Superdos. You can keep the first
64K free (ie the normal 130XE RAM) by pressing ESC during the boot process.
If you don't have enough RAM this may result in no ramdisk but allows you to
run programs that require this RAM. The ramdisk is accessed using DOS and is
assigned as drives 5 to 8. Some programs (eg AtariWriter) only provide access
to drive one. To use these programs:
1. Remove the disk in drive one and turn it off. You may now load and save
but all IO is diverted to the ramdisk.
2. Turn drive one on to use it again.

For completeness, I'm here adding the manual for Os++, which includes Dos++. The description of the Dos starts at around page 10. The build-in Dos is command-line driven, but the system disk includes also an (extensible) menu.

 

It is mostly a Dos 2.0 compatible Os but with many options added - like a 963 sections options for ED-disks, "open-and-automatically-extend" modes, XIO "validate-name" and "binary load" commands and quite a bit more. Just see the manual.os++doc.pdf

 

There used to be a stand-alone (RAM-based) version of the very same Dos - or rather two versions thereof. One that used the classical FMS area of page 7 and up, and one that hides itself behind the Os.

Did you get it from here? http://ftp.pigwa.net/stuff/collections/Pooldisk/CD1/BRADFORD/or similar? Also other places as well

 

I remember typing that out years ago from the original paper sheets and putting it out there

Hi James.

 

As I can remember I firstly found some other SuperDOS Manual text which seemed to me much little expressive then your.

I've tried to find another with Google and I say - It was really a letter with header!

 

I even can not say was it from pigwa or not ... maybe google groups etc.

All the searches were provided by Google.

 

And many thanks of course!

 

Definetly, this DOS, not being absolutely universal, solves many problems.

And solves it softer then many other DOSes.

 

Best wishes from Moscow!

OK, so I tried the superdos 5.1

 

I really liked the idea that one dos could handle all the drives I have. (see signature)

 

BUT - It could not successfully format my XF551 in DS mode. Not any disk ..

 

I could format the DS on the XF551 with Sparta dos.. but nothing but spartados reads it.

 

I could format the DS with DOSXE.. and I thought that Superdos was using the same format.. but I cannot read the XE format with Superdos.

 

So.. I am back to the start again.. looking for a dos that can read all formats.

I personally have used Superdos 5.1 with my XF551 drives formatted double sided, so i cannot understand why it won't work for you.

An unmodified xf551 is required tho ie original atari rom.

The double sided format is very similar to dos2.5 with its enhanced format. ie a second VTOC and Directory. AFAIK, only Superdos 5.1 has this format type.If this disk is put into a single sided drive, the files stored solely on side one can still be read.

Superdos of all variants is dos 2 compatible. Dos XE has its own format incompatible with everything else like atari dos 3.

Finding a dos that can read all known atari formats doesn't exist. closest would be latest sparta tho addins will need to be written to read other formats

Cannot boot into it in Altirra, only with 1050 Turbo drive emulation it goes to sector 6, but later crashes. In another modes Boot error.

Works ok only with D: patch (Disk SIO) enabled.

Do not know if aux.sys is from this version or I copied it from 4.3 or 2.9.

Track.com is standard Track Copier by Arndt Bar modified for TOMS.

Disks in SD and DD because have strange situation.

Booted from SD disk did not see DD disk dir. I got it in DD disk and from DD made SD version. Could not make ED disk. Did not try XD disk.

The drive emulator is sending the data frame after Complete faster than SuperDOS can handle -- I'll get this fixed up. This version appears to be hardcoded to 1050 Turbo as it doesn't even bother querying the drive before going high speed.

Is there such a thing? or an attempt?

 

I have been going through all the disks in my purchases.

 

I have Found a DOS 3 - which does not seem to be compatible with ANYTHING else? is this an ATARI dos?

 

2.0 2.0s 2.0s(David Young modified)

 

SO as you can see.. lots out there.

Hi!

James! Here is a link to the Atari Dos Utility that Me and a Friend of me wrote. it is called RealDos! Here is a link. http://www.realdos.net/realdos.html There is around an Atari Dos 2.0, 2.5, 3.0, and 4.0 that the Atari Corp Wrote and came with new Atari 1050 Disk Drives and later sf551 drive. Then there is dos's that are meant to be used with pbi devices and hard disks.

 

Check out my Web Site. Http://www.realdos.net

 

Take Care!

I might be missing something for the limited time I have tried to use it Steve, but I have not been able to read many disks with realdos.

 

Would be nice if I could record video or something.. because according to James above Superdos 5.1 is supposed to be able to format the xf551 is DSDD but cant get it.. it errors #138 on the second pass in the format.
