    Greetings! And welcome to AAC!

    I've moved your post into its own thread, where it will draw more responses.

    The data sheet on the 2764 will give you all the details about programming it. I believe you normally need a specialized circuit to do so - a programmer. Google returns almost 4000 hits on "2764 eprom programmer". You can find premade ones, or make them yourself -

    After that, reading is quite simple. You send the address you wish to read, assert ^CS, and read the contents of that address.
