Re: help! point blank pcb eprom
That's interesting. It's for the sounds samples I think. Usually there should be a regular mask rom. It's possible your chip is undumped.
You can't check the pictures from the auction? If there are none, can you take a picture of the whole board?

Re: help! point blank pcb eprom
Ahh, it's a Point Blank 2. Well, I can at least tell you where the chip goes on the socket.
As for how it should be oriented, if you have a multimeter you could look for common ground on both the PCB and the chip.
So in the pic above, the chip bottom should align with the bottom of the socket, so the top 6 receptacles (3 per side) of the socket will be empty.

Put your multimeter on continuity mode / diode test. Put one meter lead on ground on the edge connector, then go through all the receptables. Make a note which have continuity (which receptacles supply ground).
As for the chip, can you take a pic of the underside?
