it's a neat chip. It took ?years? to develop, and I imagine it is
pretty complicated inside.
ROM (characters) (or is this on the ROM chip of the GS?), video output
(hgr, DHGR, text, GR, mixed modes), keyboard input, speaker output,
joystick input, memory switch softswitches... etc. (IWM too?)
Why try to reverse engineer the Mega II when it is already done? Look
at the Apple IIe schematics and you'll see exactly what the Mega II
does.
