"The search for the lost Cray supercomputer OS"

The problem with keeping old stuff is liability. What say, someone is looking through some old code and finds something that his company had a patent on. What say a company just patented something that they expected would have significant value in the next year or so but they'd really had 20 years ago. The fact is if they no longer have the stuff, it can't be used against them. I've often asked what happened to Intel's user library A lot of good algorithms were in that stuff. All gone. I have a Nicolet 1080 computer that also had a user group. I'd love some of the games that they had. All gone. I now work at a semiconductor company, that I won't mention the name of, that started in business making MSI ttl parts. Most that work there think we'd started by making x86 parts. Go to the Intel museum. I've been there. From what they have there, you'd think there was nothing before the uP. Also, they never made dead end products. Unless effort is made to save stuff while it is still being used, it is guaranteed to be gone shortly after it is no longer made. Dwight
