Minolta was always a good company for providing just about any manual you wanted, and they were available on their website, until such time as they stopped their photographic division, as far as providing them in the future, sony has publically stated that they will again be available for download, once the complete transformation is done as they will be also providing parts and service for the minolta gear.
Now, I would bring this point up, if a person purchases a used item and it does not come with a manual, the company that sold it to the original consumer has no obligation to provide a manual to the secondary purchaser, that would be the responsibility of the person that is selling the used product, I myself always file my manuals so I can pass them along if and when I sell something that I no longer need. You have to remember, if you purchase a used item, you are not the customer of the company that made the item, but the customer of the person who sold you the item.
I have been a Minolta shooter for over 25 years and they were always a top notch company to deal with.
