By the end of March 2018 Next Thing, Co. (NTC) officially died and CHIP related files have fallen off the internet. The last of their sites, the forum, has ceased to function as of Oct 3rd, 2018. Prior to that I undertook to backup what I could in this mirror. For additional help there is also a wiki that the CHIPsters have assembled since the beginning. You can find it here. Its a free service so it should remain as long as individuals are still using CHIPs. Many other resources are documented there.
If your looking for live help you can try the chat channels listed on the chat wiki page. I've run into some of the users from the forum on the Discord service.
If you flash CHIPs with the images contained in these backups they will still have the original NTC Debian package repositories configured. You will need to follow the instructions in the "package repository" page to repoint your CHIPs to this mirror.

Boy the Internet is being cruel lately. I don't really want M$ scrutinizing my future projects so I've joined the exodus to other services. At least for the moment I'm self hosting projects, in a crude fashion, until I finalize a plan. Since the NTC forums have died I have removed my CHIP related GITs from my "jafcobend" GitHub account. I had only left them up there to preserve the links from various posts I've made. The only reason I'm maintaining my GitHub account is so I can file bug reports on other projects and because users are still finding and staring my backup scripts. I'll leave those there until they no longer are of use to others. Really the only thing that would still work is the NTC GitHub clone script.
Here are my CHIP related files that were mentioned in posts on the NTC forum.
I hope you find this mirror useful. If you do please drop me a line with the contact info available on my company site.
