A 520 ST. Yeah my cousin had this computer.
It was one of the first Atari ST computer. It had an external PSU and no floppy drive (no modulator).
It also had the mouse and joystick connector on the back and not under the keyboard (stupid place).
The poor man's MAC brings back memories (people called it this way because it competed against the MAC during the first years of it's introduction. The ST was designed to beat the MAC on specs but at a lower price (probably also the reason why it had no special game hardware).
