My old camera does things those fancy ones don't... stereo slides!!

I inherited this a couple decades ago, and have used it a few times. I think it still has film in it from the 80's. Not sure if there is still a place to get 35mm stereo slides developed?

I used to be quite the camera buff. Bought a lot of gear (Canon EF) in Japan while stationed in WestPac. But everything was stolen while transferring to Spain, and I was a newlywed with a daughter on the way, so I bought an 8mm movie camera with the little insurance money I got. Never got back into photography.
