The SRT 101 was my FIRST real camera... and I WISH I still had MY collection of Rokkor lenses; in a word they were EXCELLENT!!!
As Ltgk20 mentions, the Sony A mount cameras... direct descendants of the original Minolta A mount cameras, have a different mount than your Rokkor MC/MC mount lenses and the two systems are incompatible.
You can find the adapter to manually focus your MC/MD mount Rokkor lens on the A99II A mount camera here:

Ltgk20's suggestion that your Rokkor lenses would be a perfect match for the Sony E mount series of cameras is also a great alternative.
If you are prepared to spend the $3200 for the A99II, then you can buy the A7RII which uses the exact same sensor but produces slightly better image quality than the A99II. It is also smaller and considerably lighter than the A99II, and at this time several hundred dollars LESS expensive as Sony prepares to release the A7RIII to replace it.
The determining factor is the style of photography you intend to use the camera, and whether you want a small form factor similar to your SRT-101 or a traditional DSLR form factor that's larger.
Additionally, the A99II will shoot up to 12 frames per second, while the A7RII can "only" manage 5 fps.
You will ALSO need an adapter to use your Rokkor lenses on the E mount A7RII or any other E mount camera. There are currently 7 Full Frame E mount cameras: A7/A7II, A7S/A7SII, A7R/A7RII, and the brand new A9, which is geared towards professional sports and photo journalism.
ALL Sony interchangeable lens cameras regardless of mount offer focus peaking and focus magnification making them PERFECT for using older manual focus lenses. And as stated earlier, the image quality from Sony Cameras is EXCELLENT. Additionally, Sony cameras continue the Minolta legacy of innovation by offering a LARGE number of features and capabilities, usually for LESS than the competition.
So you DO have options to use your lenses.
GOOD LUCK!
