Hmm, I didn't recognize the name MZ60 when the OP mentioned it as an "oddball mount". So now I looked it up, and just to be clear - there is nothing really "oddball" about the MZ-60. It's standard K-mount. I suppose that might seem oddball to someone who only knows Canon or Nikon, but in the Pentax world, that's basically all there has been for decades now.
The only slight odd thing about the MZ-60 from from I can tell is that it was one of the earliest Pentax cameras to feature the "crippled" version of the mount that cannot read the aperture ring directly but requires an "A" setting or the use of stop-down metering. And indeed, all Pentax DSLR's have the same deal. If you want to use a lens with an aperture ring but that lacks an "A" position, you need to hit a button to get the camera to stop down momentarily to take a meter reading. Not a huge problem, but not as convenient as with lenses more recent (eg, within the last *20* years instead of the last *30*).
