Long before we found an actual copy of the Minicon 7 program book, we found the original paste-up boards. They are missing only page 9, an advertisement. Here is a PDF of photographs of all the boards.
Here are individual page images. First, the raw photos (converted from JPEG to PNG). These are ordered according to the way the book was put together: Pages 1+12 | Pages 2+11 | Pages 3+10 | Page 4 | Pages 5+8 | Pages 6+7.

And here's the full text.
Progress Report 1
We have only the paste-up boards for this progress report. Perhaps some day we will find a printed copy.
NOTE: this progress report looks very similar to the Advance Progress Report. Nevertheless, if you read the text, it seems clear that they were two separate publications.
This progress report is undated, but the Advance Progress Report says that the first progress report has a deadline of 30 December 1972, so presumably the mailing date was a bit after that.
