Anniversary: The Atari ST, Everyone's Second Favourite 16-bit Home Computer, Turns 40

Discussions on vintage and retrocomputing
It was based on the same 16-bit CPU, the 68000, as the Amiga (obviously the first) and the ST. (Not to mention the Sega Genesis/MegaDrive, the NeXT and the pre-SPARC Sun workstations, but none of those were “home computers”.)
The fate of a random 68000 fresh out of the factory was highly variable, in a way that a random Intel x86 CPUs wasn’t (it’d almost certainly end up running MS-DOS/Windows).
