Atari 800XL
The Atari 800XL, together with the 600XL, were successors of the Atari 400/800 series and the unsuccessful Atari 1200 XL in a more compact case. They could use almost the same software, just so long as the program was written correctly, because of some slight differences between OS versions.
The 800XL had 64 KB of RAM, two joystick ports and kept all the custom chips (Pokey, GTIA, Antic) of the previous models. It also featured the new Parallel Bus Interface (PBI) providing high speed access to the system bus. The new version of the graphic Antic chip offered 16 graphics modes instead of 12 for the 800.
Atari 600XL
An enhanced version, called 800XLF, appeared in summer 1984. It was equipped with the new "Freddie" chip which allowed faster memory management, especially for graphics display. This version was released in Europe with SECAM video interface.
Alongside the Commodore 64 and the Apple II, the 600 and 800XL were among the most popular home computers.
They would be replaced in 1985 with the XE series when Atari launched the ST.
Regarding the comment "and can use the same software just so long as the program was written correctly", a translator disk was provided with the 1050 disk drive (the drive released with the XL series) that allowed the 600/800xl to run all older software. What it basicly did was load the original 400/800 OS over the XL one in memory.

牛人网友DIY打造Atari 1500XL便携式笔记本编辑本段回目录
此前，国外一位名为Ben Heckendorn的网友借助Atari微机原型打造出了Atari 800便携式笔记本，虽然不能与我们现在使用的主流笔记本相比，但也是有模有样。近日，德国的一位名为Beetle的网友近日也以Atari 600XL为基础打造了一款笔记本，命名为Atari 1500XL。
为了完成Atari 1500XL笔记本的改造，该网友使用了三台Atari计算机的部件进行组合，包括14.1英寸屏幕、1050磁盘、1027点矩阵式打印机、1010磁带播放器、PC键盘。
为了证明这款改造成的Atari 1500XL笔记本能够工作，该网友还在YouTube上放出了视频。当然，如果你指纹用这款笔记本来进行正常办公或者游戏娱乐是不可能的。感兴趣者可进入YouTube查看。
