Reassembling an Atari cartridge

Well, I did something really stupid this time. I had an old Atari 800 cartridge that had lost its label. I figured that maybe something inside would tell me what kind of cartridge it was so I took it apart. First, there was no marking on the PC board that gave any clue as to what cartridge it was. But worse, I didn't pay enough attention to the original orientation of the PC board inside the plastic housing so I don't know how to put it together again. The circuit board has a big blob of glue on the top of what I assume is a ROM chip. Does that side of the PC board face the side of the plastic housing with the screw or the other side? To make matters worse, I *found* the label for the cartridge at the bottom of my box of old Atari stuff so I didn't really need to take the cartridge apart after all. Can anyone give me some advice about how to reassemble the cartridge with the circuit board in the correct orientation? Thanks! David
