TOPIC

    What is the highest bit depth the PowerBook 520 & 520c and PowerBook 540 & 540c are capable of using with an external monitor attached?

    Can the internal video RAM be expanded to provide for more colors?

DISCUSSION

    The highest bit depth at 640X480 (or any resolution) is 8 bits per pixel.

    The PowerBook 500 series come with 512K VRAM, which is not expandable.
