I've been meaning to post there for a long time. I hope someone can save some cash with this info.

There are only 4 bytes on the eeprom when it is "new". I used a bus pirate to read/program the eeprom. It runs at 3.3 volts using i2c. i2c addresses are 0xa2 to write and 0xa3 to read
I have attached a picture of the chip but it that doesn't work the pins are.
with the chip side facing you and the pins pointing up, from left to right the pins are
3v3. ground(the longest pin). data. clock. (if it doesn't work switch data and clock)

the 4 bytes are
address data
0x7d 0x55
0x7e 0xaa
0xfe 0xff
0xff 0xff

everything else is zero

Re: Canon MC-08 Maintenance Cartridge Reset File

I have attached a picture of the chip but it that doesn't work the pins are.
with the chip side facing you and the pins pointing up, from left to right the pins are
3v3. ground(the longest pin). data. clock. (if it doesn't work switch data and clock)

I can confirm that the clock and data pins are the reverse of what you have in your photo.
So, with the pins towards the top, as depicted previously, the order of the pins is as follows:

1. +3.3v 2. GND 3. SCL(clock) 4. SDA (data)
