9 DOS PACKAGES AND LW

LW works with and configures itself for many of the popular DOS packages for Atari XL/XE computers. Supported DOSes include:

Atari DOS 2.5

MyDOS 4.5

SpartaDOS X (using BANKED memory)

Even if your DOS isn't in this list, LW may well work with it, providing it follows the same basic CIO protocols as Atari DOS and does NOT use any RAM under the operating system.

Note: up to and including version 2.1, LW used to work with disk-based versions of SpartaDOS, Atari DOS XE, and many other DOS packages which used RAM under the computer’s operating system. However, since LW 3.0 uses the 14K of RAM between $C000 and $FFFF, it will no longer work with any DOS which uses the same memory space. If you need to use LW with SpartaDOS 3.2 or DOS XE, download a copy of LW 2.1 at www.atari8.co.uk.

9.1 MEMORY REQUIREMENTS

Whichever DOS you use, you must ensure that it has a MEMLO setting ($2E7,$2E8) no higher than $2000. For this reason, LW works best with SpartaDOS X which – when using BANKED memory (as it must with LW) – boasts an impressively low

MEMLO.

LW works well with DOS 2.5 and MyDOS using normal sector buffer configurations. Resident handlers and TSR programs are unlikely to work with LW using these DOS packages.

As well as all conventional memory from $2000 to $9FFF, and the cartridge memory from $A000 to $BFFF, LW also uses 14K of RAM under the operating system between $C000 and $FFFF. LW will switch out internal BASIC when using DOS 2.5 or MyDOS, but SpartaDOS X users must run LW with the “X” command, since the library must be disabled.

9.2 ATARI DOS 2.5

These systems require no special handling by LW and special DOS features such as subdirectory and command line support will be inactive. LW will disable internal BASIC automatically with this DOS. By default, LW will use all available extended memory (not occupied by a RAMdisk) for extra text buffers under DOS 2.5.

9.3 ATARI DOS XE

LW 3.0 will not work with DOS XE.

9.4 MYDOS 4.5

XL specifications

The Atari XL series, launched in 1982, represented a significant evolution in home computing, building upon the foundation laid by the Atari 400 and 800 systems. This line of computers included popular models such as the Atari 600XL and 800XL, both of which combined affordability with robust capabilities, making them attractive options for home users, educators, and enthusiasts alike.

One of the standout features of the Atari XL series was its color display capabilities. The systems supported a resolution of 320x192 pixels with a vibrant palette of 128 colors, which enabled rich graphics for games and applications. This was complemented by the system's powerful Antic graphics chip that allowed for advanced video display modes, making the Atari XL series particularly popular for gaming and multimedia applications.

Another key technology driving the Atari XL series was its use of the 6502 processor, which delivered efficient performance and allowed for smooth multitasking. The systems typically came with 64KB of RAM, expandable to 128KB, providing ample memory for running multiple applications simultaneously, a notable feature in comparison to other microcomputers of the time.

The Atari XL series also introduced a new, user-friendly operating system known as Atari DOS. This improved disk management capabilities, making it easier for users to manage files and applications on floppy disks. The systems were equipped with built-in BASIC programming language, enabling users to dive into programming and coding, fostering a generation of hobbyists and developers.

Each model in the Atari XL series came with a distinctive keyboard design, offering both a chic and functional layout. The keyboards were known for their tactile feel, making them suitable for typing and coding over extended periods.

Additionally, the Atari XL computers were compatible with a wide range of peripherals, such as printers, modems, and disk drives, enhancing their versatility. Users could also take advantage of a rich library of software, including educational programs, productivity tools, and an ever-growing selection of games.

The Atari XL series not only boasted solid technology and capabilities but also garnered a devoted community. The systems contributed to a vibrant culture of gaming and computing in the early 1980s, which remains fondly remembered by enthusiasts today. With their combination of innovative technology, user-centric design, and a diverse software library, the Atari XL series played a crucial role in the evolution of home computing.
