Mac LC III ("Vail")
Mac LC 520 ("Hook")
By R. Belmont
These are basically identical '030 machines, except the LC III is a pizzabox
while the LC 520 is an all-in-one with a 14" Sony Trinitron built-in.
LC III uses the Egret ADB microcontroller while LC 520 uses the later Cuda.
Everything else is the same.
