Conclusion Preserving UNIX is a pastime, like preserving old cars. It will one day be useful for computing historians and archaeologists. Since PUPS was formed in 1995, we have put together an impressive collection of UNIX material. We have a network of people with a large amount of old UNIX knowledge. Our greatest achievement is to make cheap UNIX source licenses available.
Preservation is ongoing.
Donations of UNIX material to our archive is most welcome.
