Integrator/Integraph, any Idea where to find one

[mfqrdf]

Almost seven months ago, before graduating with my BS in Naval Architecture, I had a professor who stopped me and pulled me into his office to discuss this. He said if there was one thing that I should try and get my hands on it would be a mechanical integrator.

I am wondering if anyone (after they stop laughing at me) has any idea where I might be able to find one, or at least start looking. Names of manufacturers or model numbers would also be helpful for internet searches.

Thanks

Last time I saw one in real life is about 30 years ago.
