Help with fried Atari 520ST

Recommended Posts

Howdy, new in here, want to ask for some help if I may: I am new in the platform and got an Atari 520ST from a friend, just the CPU. Searched online and found the schematic for the power and bought the DIN, connected to the 2 5+, +12, -12 and grounds. When connected smelled burnt and saw a little white smoke. Disconnected immediately and later realized the schematic was backwards, and was not the cable, so I basically switched the cables. 
Feeling bad but looking for guidance on how to find the burnt or faulty components to replace. Any help will be greatly appreciated.

Serious mistake. It got power reversed, so actually chips got -5V instead +5V. Most likely many of them is dead. And likely will be cheaper to get another Atari than repair this - not to mention time needed to find components ..

If it's truly dead, I hope you can sell it off as a parts machine. The case, keyboard, some ports like the cartridge, ACSI, monitor and disk drive ports can be used by others.
