Hi David,

Actually I don't think there are 24C00 chips on DDC links. These chips
only provide 128 bit (16 bytes) of storage space, which is insufficient
to hold EDID data. So I think these are 24C01 chips (1 kb) which
behave like the 24C00 as far as I2C addressing is concerned (i.e.
answering to all addresses 0x50-0x57.) Apparently Atmel make such
chips (the datasheet doesn't mention any I2C address, and the 3 EEPROM
pins which are typically used for address selection are labelled "NC".)
