Q:Inside a IIC

Does anyone have a schematic of an IIC?
How about a list of all the different chips and their meaning, like GLU,
SPI, MMU? Iï¿½m trying tho trace the problem why 3 of my IICï¿½s donï¿½t work.
All have similar problems, strange characters on screen and no boot from
disk, disk will spin and try to read. Speed of the disk is ok. Someone
suggested the upper memory had a bad chip, but replaced those too with
no luck.
TIA
