How do you change the calc's interrupt speed?

   No, TXTSHADOW wouldn't do something like that.
       You may have accidently altered the calc's interrupt speed(port 4) 
 that would cause the cursor and keypresses(_getkey) to be extremely 
 slow(so slow that you think it locked). If you modified the interrupt 
 speed, you can only fix that threw a program. Reseting the memory does 
 nothing at all(at least on an 82).
