Nostalgia again.  The 1130 was my first computer as well, at
American University.  To use it, one passed a basic operation
and a basic FORTRAN programmed instruction course, and then
signed up for machine time.

When I was first introduced to the beast, the computer center
manager carefully warned me NOT to push the IMMEDIATE STOP
button, because it might cause a mid-instruction halt which
would leave the disk (with a HALF MILLION CHARACTERS) inconsistent.
I was warned to use INTERRUPT or PROGRAM STOP.

Anyway, I soon experienced a hard loop, which turned out to
be a hardware problem.  I punched interrupt and program stop
until my finger was sore, with no change.  What to do?
I COULDN'T push IMMEDIATE STOP, could I?

Aha! Another alternative occurred to me.

I turned the power off....
