XXXROM Reader version 0.0.2

This is some code that will use the prop to address locations in a 64K eprom. It's pre-set for 64K right now because that's all I have available to test it with. Future versions will include support all other parallel memories, including RAM and older microcontrollers/processors.
Right now, this code just addresses all the memory locations in an eprom, reads the data, and displays it all on a tv.
The wiring of the eprom to the prop does take lots of time, unless you were to make a PCB with a socket or something. Here's the general wiring info:
EPROM | PROP
A0-A15 | P0-P15
D0-D7 | P16-P23
EN | 27
CS | 28
EDIT: I attached revision 0.0.2 as well as a picture of my setup of the reader.
