iirc, the rapidfire 'push-push' shifters required no disassembly to remove the cable... with the cable detached from the derailleur and the inner wire pulled free of the housing, shift into the lowest (cable all-the-way-out of the shifter) gear, and push the cable back into the shifter... on the side of the shifter opposite where the cable comes out should be a small circular hole and the cable head will be protruding there... sometimes there is a kink in the head-end of the cable and the head does not exit the hole perfectly, and it takes a few tries to get it out.
IF the calbe is totally corroded or jammed in the shifter and pushing on it does not free it, you may have to remove the bottom cover off the shifter to figure out a method to work it free. Don't worry about the shifter springing apart - the bottom cover is just a cover and the shift mechanism is (or should be) held securely together by another nut underneath the cover.
Eidt: I just went to the garage and got an old rapidfire push-push shifter (I think mine is a 100 or 200 GS)... Cyccommute was right - there is space above the 'paddles' where the head of the cable should come out no problem, not a little round hole.
Edit2: Here is a pic of the shifter. You can see a little spot of light above the top paddle... this is the hole through which the cable passes. The head of the cable should come out thought the space above the top paddle.
