The Atari 800XL
|Word Size:||8 bits|
|Physical Address Size:||64KB|
|Operating System:||Built-in BASIC, and Atari DOS|
The Atari 800XL replaced the earlier 800 model. One difference is that the 800XL is a single-board construction while the 800 had two internal boards and by 1983 that had become too costly to produce. The 800XL also came with 64KB of RAM (the 800 had 48KB of RAM), in addition to 24KB of ROM. The 600XL and 800XL models were the first Atari computers with BASIC in ROM.
The Atari 800XL introduced a new high-speed expansion bus called "Parallel Bus Interface" or PBI.
- Two joystick ports on the right-hand side
- Serial input/output, PBI, composite monitor, TV/RF at the back.
The Atari 800Xl had a good quality real keyboard instead of the cheap membrane keyboard of some other models.
