Hmmm, looks like somebody tried to fix the problem at least as of Ultrix 2.2,
but they changed the first two delays to 5 sec instead of the second two...

Anyway, if you want to try changing the final delay to 5 seconds or some
other value, the procedure looks something like this.  Make sure that
that the code sequence of pushl $x, calls matches before you try to change
the numbers.  8-)

Disclaimer:  I don't have any unibus tape emulation installed so I have no
             way of actually testing this patch.  Use at your own risk!
