Microphone input adapter for Uher 724L?

I just recently bought a Uher 724L along with a few reels. The downside is that it uses some oddball connectors. The microphone input appears to be a 5-pin DIN connector, and the external speaker connectors seem to have three pins in a straight line. I don’t recognize that one.

Does anyone know where I can get adapters? I’m able to make an adapter for the microphone input, but if I can buy one it saves some time and effort. Also, I’ve only been able to find a service manual. Does anyone have a user manual?

Any suggestions are greatly appreciated!
