Rick Morris recently had his Model III’s power supply go poof. He was kind enough to let me know that recap kits can be found at:

July 7, 2025 – Updating Ad Images in Archive
I have finished going through the OCR’d 80 Microcomputing magazines looking for advertisements which were missing from the search results. All in all, 483 more advertisements have been added.
June 30, 2025 – Updating Ads in Archive
Over the weekend I licensed ABBYY Finereader 16 and ran all 102 issues of 80 Microcomputing through it. While I am surprised at some bugs that seem to have survived 16 iterations of the program to make themselves known almost immediately, it has allowed me to leverage the dtSearch indexing software to help augment the graphic parts of the archive, mostly adding missing blurbs and ads, although also helping to correct some author errors.
The workflow is that I do an archive search for program whose author is known but which doesn’t have an ad. I then use dtSearch to try to see if they advertised in 80 Microcomputing. If so, I use GhostScript (command line) to extract to the page from the 80 Microcomputing to TIFF and edit accordingly.
While not perfect, it helped.
