Hey..
By the way, does any one know which of the 3 chips is the Z80??
on the motherboard.. This is my guess, the chip made by TI is the ROM
(naturally), The chip in the Center(in the CE version) is the Z80, but it
only has 28 pins.. what gives? the other chip has a hundred or so, which
rules that..I bet that's the memory chip.. If I'm correct, then I've got a
couple of other questions too.. the center chip does not communicate
directly to the LCD board either.. any info would be appreciated.
