A useful trick is to use a 28 pin turned pin socket as a carrier. Fit the
IC, apart from the snapped legs, of course, then solder thin wires to
'bridge' the broken pins into their appropriate sockets on the IC socket.
The whole assembly can then be plugged back in.  If you've broken the legs
off at the package edge, you're out of luck!

I've often used this trick to get copies of damaged EPROMs, then burn new
ones as working replacements.
