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.
