The Atari 600XL is an 8 -bit home computer produced by Atari, together with the older brother Atari 800XL, between 1982 and 1985. Unlike the ears 800XL, the 600XL is smaller and has 16kb of RAM in the place of 64kb.
Already having a Atari 800XL in the collection, it seemed logical to buy even the 600XL, for completeness!
I found an opportunity on eBay of a computer that was to be functional, but, upon arrival, the screen continually showed the pressure of a keyboard button, as if it were in short circuit.
In the lot, in addition to the computer, there was a power supply and an Atari 1010 cassette player.
The Atari 1010 datassette connects to the computer via a SIO cable, which is not present in the purchased lot, but which I already own.
Startup screen
The start -up of Basic start screen is very simple: it only shows the writing READY.
If an Atari 1050 floppy disk drive is connected, the computer automatically attempts to boot from disk and loads its contents.
Always with floppy disk drive connected, holding down the OPTION Upon ignition, the computer does not load the basic. In this case, there is more memory available to perform some programs and games that, if the basic were in memory, would not start correctly.
When the Atari 1050 floppy disk drive is not connected to the computer, holding down the OPTION At the lighting, the computer self test starts. Through the self test, it is easy to check the correct functioning of the 600xl.
