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).
Erm the only negative thing was the basic sound chip and no WOM like A1000 for OS disk to load. The styling was gorgeous, and the mouse/joystick ports were on the right side same as a C64.
At £399 for the model with a modulator built in ie similar price to the Commodore 128 (but not the bulky FM with built in disk drive) it was great for pixel art, second only to the £1250 A1000 at the time.
The bad point was the OS loaded into regular RAM so a 512k ST was left with about 300kb after the disk loaded. Also there was no colour monitor available on launch so all you saw was the monochrome screen in shop displays with the boot disk requester
I've got one of these disks and it's still new and never used too.
