Atari 520 ST Computer and Accessories Development System
[ATARI520] $99.00

Condition: used
This Atari 520 ST was used for development by US Digital Corp.
It includes the Atari Development software and documentation.
Also included are several flip-lid storage boxes for the floppy disks.
Because this computer was used for development, it includes an additional unusual accessory, a five inch floppy drive (with a box of disks).
The monitor, power supplies, keyboard, mouse, joystick, 3.25 inch floppy drive and cables are all included.

Also included are the development manuals for the Atari ST.

Note: Because this is a development system, the operating system is boot-ed from a floppy disk. So the TOS boot floppy disk must be in the disk drive to boot the system. As long as you do not power down the system, you can remove the boot floppy from the disk drive once the system has completed the boot-up.

We are not able to fully test the system, as the five inch floppy accessory is disassembled. The power supply for the five inch floppy appears to support two 1/2 high drives, but the drive that is included is a full height drive. There is a switch on the back panel that has some wires connected to it, but they don't go to anything. Not sure what it is intended for.

While this computer does power up, we do not have a way to fully test this computer to see if everything is fully functional. Because of this, the computer are sold as-is.
