AFAIK only the internal timer and the [ON] key (perhaps also the link port) 
use the interrupt mode "im 1". With normal batteries the speed is usually 
about 120 ints/second. If you got a regular Ti-83 (so a 83-), follow this 
link for a program to find out yourself:

(I'm planning to port it to the 83+)
