+OS++ is an Open Source rewrite of the ROM operating system for the Atari
+XL/XE 8-bit computers, capable of running many games and other programs for
+the Atari.
+
+OS++ also includes its own DOS, which is capable of running most
+disk-based software that works with Atari DOS 2.0S. OS++ DOS is only
+booted if the disk image in drive 1 is not bootable, so it won't conflict
+with bootable DOS disks.
+
+OS++ is written in 6502 assembler. You will need cc65 installed to build
+this package (though not to run it). cc65 is available at SlackBuilds.org
+
+This version of OS++ has been slightly modified to work with the Atari800
+emulator. See /usr/doc/os++-20070109/README.atari800 for more information.
+
+If you have the SlackBuilds.org atari800_roms and atari800_os++ packages
+installed, you can adjust the symlink at /usr/share/atari800/atarixl.rom
+to choose which OS will run (or, edit ~/.atari800.cfg, or run atari800
+with the -xlxe_rom option).
+
+Note: OS++ only replaces the OS ROM. If you want to run BASIC programs,
+you will still need an Atari BASIC image, or a freeware/PD BASIC
+interpreter such as Turbo BASIC XL.
+
+If you'd rather use the original ROMs, install atari800_roms instead
+of this package (or in addition to it, and change the symlink at
+/usr/share/atari800/atarixl.rom as desired).

+
+This copy of OS++ has been slightly modified to allow it to work with
+the Atari800 emulator. Specifically, Atari800 patches the operating
+system ROM to support high-speed emulated disk I/O. Unfortunately,
+when this is done, OS++'s checksum routines correctly detect that the
+ROM checksum doesn't match, and the OS doesn't start.
+
+The *correct* way to fix this is to make Atari800's ROM patch actually
+update the stored checksum after patching. For Atari800 2.1.0 and
+previous, the workaround is to replace OS++'s checksum calls with NOPs,
+which is what's been done to this copy of OS++ (future versions of
+Atari800 will hopefully have proper support for OS++)
+
+Note that OS++ only works correctly with Atari800 if the emulator's
+high-speed SIO patch is enabled. Without the fast SIO patch, OS++ can't
+read the emulated disk drives. Most likely, this is due to Atari800 not
+emulating the hardware 100% perfectly.
+
+Also, this is documented elsewhere, but worth a mention here, too: OS++
+does not include BASIC! Machine language programs normally don't call
+the BASIC cartridge, so they will be unaffected. If you want to be able
+to run BASIC without using the copyrighted Atari BASIC ROM, try the
+excellent public domain Turbo BASIC XL.
