I uploaded a few Aardvark manuals, which came in handy when I was testing out some software recently. Search OSI aardvark at archive.org to find those. Perhaps the OSIWEB.org webmaster will want to mirror them with their comprehensive documentation.
Also uploading a neat OSI sales flier I scanned, https://archive.org/details/osi-why-wai ... 8_0001.jpg
