>No, you need to transfer a backup I.e. it's impossible to type it in on the >keyboard. Thats not actually true, you can get a backup from anouther calc that already has CrASH or ASH on it. If you can't find someone with it I'd ask my math teacher if he/ she has one you could barrow, and if they don't have one find out who the head of the math department is and ask that person.
