BTW probably a large per centage of people on this site don't even know what microfinche is. Is it 16mm or 35mm? Do you have a reader? Can you convert it to scanned images?
In my case, it's actually sheets. I have a couple of portable readers that will accept the sheets, and move between the pages. The portables don't have the ability to scan an image, however.
I had received basically no help, or even suggestions, until now. I'm glad the thread was re-opened, as this is the best lead I've had so far. I know the company, and will try to find a bottle locally, or order from Adorama.
I have a couple of duplicates of the 'fiche, so I can experiment without losing unrecoverable information. There was a company that had bought the rights(?) to the tech manuals from Canon. At any rate, they were the distributor, and Canon Technical Services in New York forwarded requests to them, a few years ago.
I've left the 'fiche untouched, and will wait until I hear further, or find a bottle of Edwal film cleaner.
I would have thought many people would have handled microfiche, as library newspaper files are on them, in 35mm format. Also many magazines, and the Library of Congress further much historical data in that format. The portable scanners are very handy units. I bought these a number of years ago at an MIT flea market.
Thanks,
