A couple years ago I started work on a program to retune OSCCAL by modifying the signature page. I had found some old (dating back over a decade) posts discussing the undocumented HVSP commands. I spent a few days trying to figure out the low-voltage serial programming command to write the signature page, but then moved on.
Now I'm trying to help someone add the OSCCAL modification to their HVSP project, but some of the discussions seem to be gone. Here's one of the threads I bookmarked:
Posts by Giorgos_K are missing from the thread. I also recall reading at least one thread more than 10 years old that discussed the undocumented commands, but can no longer find it.
I tried archive.org, but avrfreaks doesn't seem to be in their database. Is there a way I can see these missing posts, or has someone saved any of the old discussions on the undocumented commands?
