Hey Juan,

What you are doing is considered sacrilege! :)

You'll find that once you tear into the cartridge (yes, it takes some force to separate the two halves once the screw is removed), it will likely not have a 24 or 28 pin ROM socket, but a tiny epoxy blob which will make your experimenting a bit more interesting.

The cartridges that tend to have the 28 pin ROMs are the newer CoCo 3 carts like Shanghai and Thexder.  Before you take a cart apart, pull back the card edge cover at the bottom of the cart and hold it to a strong light, then peek on the inside top of the motherboard.  If you see a tiny black blob, you know it's not the cartridge board with the  PROM, so it's probably best to leave it be.
