Help on interfacing CAT35C104 Serial EEPROM to my arduino UNO please.? Answered

Hey,
I'm still semi new to Arduino, but I can read/write to analog/digital pins and communicate via I2C and SPI with other devices and micro controllers, but those are more widely known and I have here with me a ton of 8 PIN DIP, CAT35C104 Serial EEPROM IC's.. And with all that EEPROM lying around I wanted to put it to some use. But I am still not an expert and don't know how to begin to interface it to my Arduino UNO R3.. :L

Specifically it shows: CAT35C104 Serial EEPROM 4kb data storage, 512 x 8 bit registers, 256 x 16 bit

Can anyone help me get this to work?
I also have trouble with "opcodes" kinda confused..
right now I know the times it takes to read/write, and the clock frequency (1MHz)
And the pin diagram..


Any help would be appreciated!!!!!

If you can use SPI, you can talk to this chip - just rather than using the arduino built in eprom library, you have to send and receive packets of information with instructions then listen for the response.

It says in the Serial library that SPI speeds are 0 - 4, 4 being fastest, this specific EEPROM runs at 1mhz tops, so what is that translated to SPI speed???

I don't know - it's not documented very well - just try it and see...If I recall, it's not very fast on the duino.
