My grandfather's company had a single user NCR 499 "business
computer" with core memory. If the power went out, once it was
restored we could restart the computer from where it was by noting
the prompt (the machine had a built-in tty), searching for it's hex
address in the asm listings, punching it in and pressing <GO>.
Very handy.
