Re: Ballblazer Carts...

I used a solder pot to remove a bunch last year, similar technique to
what Alex indicates. It was not as easy as I had hoped and took a bit
of trial and error. One thing was that sometimes the pins (maybe a
couple) are bent prior to the chip being soldered originally, which means it
does not always just fall out easily when the solder is moltant. And afterwards
as well as cleaning up the pins as Alex says you may have to straighten
them out. There is also the time of taking the cartridge out of the package,
then taking the pcb out of the plastic cartridge (which has one screw
beneath the label), then popping it apart. So dont under estimate the
entire time of the complete process.
