I just scored a golds gym treadmill. Hoping to re-purposed the motor and controller. The controller is an MC1618. Wondering if anyone has any experience with those? How do they compare to the more popular MC 2000 or MC 2100? Numerically it seems like it would fall somewhere between the MC 60 and the 2000. Trying to hunt down a schematic for it now. Any thoughts would be appreciated.
