I'm wanting to insert my own routine in int 1ch (timer tick)

I've been told that I can just call the old interrupt routine from my new
one.  This would seem to incur a lot of overhead, and its unclear who 
will maintain the stack.

What I'd like to do is just to JMP to the address of the old routine once
my routine has finished.  Has anyone figured out a way to do this?

Thanks,
