you hook power up, an RC, and then reset will return the PC back to the start (I think it actually starts at the very last location in ROM), and I used the clkout pin next to the RC pin to time the dump.

RA4-7 and RB0-7 is where the data comes out. you have to pull test high, also. I just have it wired to 5V by the looks of it when I gave it a quickie look-see friday.

you can just wire it up on a breadboard for testing. that's how I figured it out the first time.

Woo-hoo, I've got bits. Thanks! I was just missing grounding RA3.
