Teleprint 390

On *my* 390 there is a slightly different "call control unit". But I 
have several 33s and nearly each has a different ccu. Normally you don't 
have to worry about that if you have a current loop device in working 
condition. There are also a lot of different wiring options for the 
machine.....

Hey, that's cool. PCBs are normal in all CCUs.
It will be hard to find schmematics for that.

... but there's no information about glueing together broken pieces of 
grey plastic....  :-)
