I just bought an MRC command 2000 dcc systemat my local train show for $20 (brand new in box). Anyway I just wanted to know if there are any things I should know about the system (what not to do, etc.) and what type of decoders I should use with it since it is such an old system. Thanks for your help!
It has 14 speed steps. So modern decoders need to be set down to 14 speed steps.
I had static problems with one of mine. Every time a tiny spark jumped from my fingers to the unit it would flake out and have to be reset. I grounded the case and the problem went away.
My favorite option on that unit is the remote throttle. That lets me control 5 locos at once without switching between channel A and B.
