Thanks Dave for your thoughts. The MTBF-factor is of course a hard caught animal, I guess I have at least two objectives with a project like this: 1) Try to make it run by repairing it or work around it's faults. 2) Treat it as an self educational exercise aiming at more modern machines and controls.
This could done I guess, on another machine machine but if we decide to refurbish it with a new control it's good to dig inte a working system because somewhere you have to cut the wires between the control and the machine. Get acquainted with the system is a good thing to do if it's possible, right? I can observe the behaviour of the switches in the diagnosispage and I think this is a great way to find out how it works, by observing it's various parameters in action. You may also monitor the signals on the physical wiring when the system is running making use of logic analyers, oscilloscopes and multimeters. Yes, I have a background in repairing electronics, analogue and digital, the analytical way. Nonetheless, it still may turn out to be too cumbersome so doing this on a more modern system should probably be a better investment. I'll talk to Johnny about this.
