Tantos took over working with the disk. He rewrote the recovery tools, plus a simulator for the software and supporting equipment like printers, monitors, keyboards and more. For the greater part of the last year, he arduously reverse engineered the OS from the image. Despite a few remaining bugs, the Cray OS now works.

This is quite, quite an amazing journey.

That's amazing work. It's not like the Cray architecture was a simple design to start with, either.
