Have any of you seen this site.http://www.tinet.cat/~fmco/ Its awesome. I built this system from plans off the internet. All you need to get started is the NanoX-S88 command station, GenLi computer interface and a computer running JMRI which is free software. Paco's website and hardware designs are really cool.Check it out. If you have any questions you can contact me and I can tell you what I know about it. Also I have videos of it posted on youtube. http://www.youtube.com/user/dreambuilders48808#p/a/u/2/3weLD77hTjA
