Perhaps, then, I don't understand fully what Setexc does. Under both
normal TOS and MiNT, does a new vector installed by Setexc automatically
fall through the old vectors? That was my primary concern with Setexc...
By simply changing the 'jmp 0' to 'jmp old_vec' I can easily jump through
the old vector with little manipulation. But with Setexc, how can I still
execute the old vectors painlessly?
Sorry, but I'm a bit new to this whole exception vectors thing... (can ya
tell? 8^)
