Quoted from AndyC:I tried using the tool to no avail ended up taking the board out and used a small flat head screw driver. I just couldn’t seem to get any movement of the rom using the tool.
Yea, the longer they've been in there the more stuck they seem to be. I believe there's a bit of oxidation that you have to break through to get them to start moving.
The real issue with using a screw driver to remove ROMs is resisting the urge to pry up on the chip by placing the tip of the driver on the PCB under the chip since most sockets are open in the middle. Doing so places the blade of the driver on the surface of the PCB and can cut/short the traces which run under the ROM (or any other socketed chip). This is an easy mistake as most folks will either slide the blade across the PCB or lift up on the driver while the tip is on the PCB surface in an effort to pry up on the chip. Both of these actions damage the traces.
The other issue folks have when the chip is in close proximity to other chips is they accidentally put the tip of the screwdriver under the socket and pry up the socket too.
It takes a bit of practice and a steady hand to slowly work up on the chip. I typically work the chip out by sliding the driver tip between the socket and the chip just inside the legs. Since most sockets are open in the middle, you need to apply pressure between the socket and the chip and that's going to be just behind the pins on each side. Sort of a wiggling/wedging operation that uses the inclination of the driver tip to push up on the chip and down on the socket. I work each side a little bit at a time, switching back and forth. The most difficult portion is at the end when the chip wants to tip up like a hinged lid and you can end up bending the crap out of the last few pins on both sides.
