- 130RAM: 251 usable sectors * 250 bytes/sector = 62,750 bytes
- SSDD: 715 usable sectors * 250 bytes/sector = 178,750 bytes
(Note that when DOS XE reports free disk space it truncates the
number of bytes free to the nearest 1000 "K" bytes. For example, an
empty AT810 disk is reported by DOS XE to have 86 K bytes free.)

DOS XLE
-------
DOS II Version XLE ("DOS XLE") (P) 1990 Atari (Germany)
Andreas Koch writes (January 2010):
"programmed by Reitershan in 1990 (as requested by Atari Deutschland then
for the XF551 drive), it is not only similar, but fully compatible to
Turbo-DOS XL/XE (also by Reitershan). It uses the well-familiar DOS 2.5
DUP-menu, with a few enhancements, like e.g. 1-8 for Dir. of drive 1-8,
formats 90KiB-360KiB and RAMdisks up to 256KiB; there is even an option (P)
to switch back to standard DOS 2.5; this DOS has been written with the
source-code of DOS 2.5 (made available for Reitershan by Atari
Deutschland), so it is as compatible as possible to DOS 2.5 but still
offers some enhancements; luckily all Turbo-DOS XL/XE utilities can be used
with this DOS (e.g. the RAMdisk-driver from Turbo-DOS!);

Subject: 7.3.2) What are RealDOS, SpartaDOS X, and XDOS?
The continuing development of various modern mass storage options for the
8-bit Atari computers has necessitated ongoing development of supporting
disk operating systems. This section describes full-featured disk operating systems (DOS) for the Atari that remain actively developed today.
RealDOS

Subject: 7.3.3) What are MyPicoDOS, Micro-SpartaDOS, and LiteDOS?
A "miniature DOS" / "gameDOS" / "microDOS" is a DOS version that is designed
to provide minimal capabilities. Typically, this type of DOS makes the disk bootable, and supports the launching of files on the disk. This section describes current miniature DOS versions for the Atari.
MyPicoDos
=========
MyPicoDos 4.06 (C) 1992-2017 by Matthias Reichl
A "game-DOS" for DOS 2.x/MyDOS compatible disks with the following features:
- It supports loading of COM/EXE, BIN (boot image) and BAS files.
- It works with single and double density (hard-) disks from
720 up to 65535 sectors.
- Drives D1: to D8: can be accessed.
- It supports MyDOS style subdirectories.
- It supports Bibo-Dos style long directories (128 files per disk).
- It supports XF551 format detection.

Speedy, AtariSIO/SIO2PC/APE/...), Happy 810 Warp Speed, XF551 and Turbo
1050, up to 126 kbit/sec (Pokey divisor 0)
- It supports displaying long filenames and a disk/directory title.
- On XL/XE-type computers MyPicoDos can automatically switch BASIC on
when loading a BASIC program, and switch BASIC off when
loading a COM/EXE/BIN file.
- Joystick support: either use arrow keys or a joystick to select
the file.
- Optional built-in atariserver (AtariSIO) remote console.
- Separate "barebone" version without high speed SIO support and
remote console support (for those who want to save space)
- Separate boot-sector-only version "PicoBoot" supporting a single
COM file on a disk
- Separate "SDrive" version which configures the SDrive to use
110 or 126 kbit/s transfer speed.

System of Atari DOS II.
- Introduced April 3-5, 1981 at the West Coast Computer Faire as: "CP/A"
- Original version of the Console Processor and the original version
("version 2") of the File Management Subsystem (FMS; identical with that of

- Format developed with Atari for the Atari 815
- 256 total bytes/sector, with 3 bytes of each sector used to
address the next sector.
- 40 tracks * 18 sectors/track = 720 total sectors, with 13
sectors used for software control or unused by the FMS.
- Data capacity per diskette:
707 sectors x 253 bytes/sector = 178,871 bytes/disk
- 13 special sectors:

-----------------------
- Primarily developed by Charles W. Marslett
- Menu driven, modeled after Atari DOS 2
- Uses Atari DOS 2 single and double density file systems, extended with
support for larger capacity diskettes
- First Atari DOS to support dynamic density changes (user-initiated, but
without rebooting the system).
- Earlier versions were sold commercially; 4.5x versions shareware/freeware
- Versions 3.x sold by SWP for use with the ATR8000:
- 3.0x versions are the standard releases
- 3.1x versions have an integrated R: handler for the ATR8000 serial port
- Sold by SWP in disk-side or system disk builder pairs. Known version-
pairs include: 3.08/3.12, 3.09/3.13, 3.011/3.16, 3.013/3.18, 3.014/3.19
- 3.2x versions were developed for use with the never-shipped SWP ATR8500
- Versions after 3.08/3.12 include support for subdirectories
- RDOS 800 (early name ROMDOS) is MYDOS 3.0 but can occupy less user RAM.
- Revisions: 0.0, 0.1 (1984), 0.11, 0.12, 0.14. Versions:
- Can reside in the 4KiB unused memory address space in the 400/800
(49152-53247 or $C000-$CFFF) for permanent availability on ROM
(i.e., Newell Ramrod personality board or CDY Omnimon! board)
- Can reside in OSS SuperCartridge banked RAM address space
- Can reside in standard RAM
- 0.14 additionally can reside under XL/XE built-in BASIC
- OMNIDOS is Wordmark ROMDOS/RDOS and CDY Omniview on one 8KiB chip for
