Well, that is written from a US perspective (EDIT: At least that's what I thought, but it might not be, actually

) - here, first the NES killed the home computer games business, and then the IBM PC killed the "business" machines. Bye bye TRS 80 Model 4 and all machines that were more business oriented. Remember, Amiga and Atari ST were mostly European Success stories. Amiga, for example, never got a foot on the ground in the US here, because too late and the IBM PC had already claimed too much ground. Buyers didn't care for Amiga sound and graphics and multitasking, but wanted PC compatibility. The IBM PC success started much later in Europe than in the US.
