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.
I think what these people have done is truly wonderful. I also feel that this is the best way for computer history to be taught is to read about what these guys did, then hopefully one day buy a cheap reproduction system based on FPGA’s and punters learn to drive and dev on it. Then people can really appreciate these machines and what they achieved.
Well done guys! Really well done!
Why didn’t they just hit F2 while booting? That’s how I recover the OS on my laptop…
That’s dedication!
That’s amazing work. It’s not like the Cray architecture was a simple design to start with, either.
Not sure I’d have the persistence to maintain such an endeavor. Fascinating, though…

I can’t beleive people threw out the orignal Cray I. It was so cool, just to look at, regardless of the cost or performance. I would have tried to save it. Must have been a bean counter’s decision.
I just want to thank you for sharing your information and your site or blog this is simple but nice article I’ve ever seen i like it, I learn something today. http://senetix.com/rapid-prototyping/“>Pcb . is something more that concerns me.
