Hacking and old Leica TCS SP2

I received an old Leica setup that our medical school was getting rid of. IT consists of a TCS SP2 scan unit with PMTs and galvo scanners, some lasers, and a DMIRBE. Is there anyone here who has advice for salvaging the PMTs and the scan mirrors? I don’t have the computer that came with the system, so I don’t have any hope I could get it working like it originally did.
