_{Cover of the October 1979 issue of Byte}

I'm not sure if Byte was the first computer magazine but I think of it as the original computer magazine. It was around before home computers were even a thing. Nevertheless, Byte was covering "small systems" or microcomputers used by businesses and hobbyists starting in 1975. The October 1979 issue includes:
