i have a sony alpha100 with a minolta mount. i found some nice minolta lenses from the 70's, but they don't fit. did the mount standard change in the last 30 years? is there an adapter for this?

When Minolta introduced the Maxxum autofocus SLR in 1985, the first successful one ever, they changed the mount. All MC, MD mount lenses were left behind. There are adapters, but none of them support autofocus or autoexposure (though some do support focus confirmation) and all are teleconverters of some sort. I've got a 'Minolta 2X M/A Conterter - S' (the 'S' is for shorter focal length lenses, < 300mm), and have even used it ocassionally, but it requires me to relearn how to use my camera every time I do.

Be careful when shopping for such a product, as some only work with the early Maxxum film cameras but don't work on the more recent models especially the digital models.

Also, many of the newer Sony Alphas don't like working with them since they don't tell the camera what kind of lens is attached. I think the A100 will work ok though.
