I began design and development with research on other projects with similar requirements and AGC was one of them, I remember. The difference in my case was that I did not have simple non-volatile memory like AGC had, I had flash chip with no wear leveling. To protect the flash from premature death I had to design my own database to store data in form of deltas appended to the file. When it started it would scan from the beginning of the file until last complete record and start from there. When the data in the file reached preset size all live records would simply be rewritten to beginnig of another file.
