I too have had problems with this site, I think its just not well organised/maintained. The best schematic and code for mobile decoders I have found is at: http://ourworld.compuserve.com/homepages/Dprobst/railroad.htm Nothing about command stations though. Ian ih@ey.bm Please respond to PICLIST@MITVMA.MIT.EDU To: PICLIST@MITVMA.MIT.EDU cc: (bcc: Ian Havercroft/IT/ErnstYoung/BM) Subject: Troubles retrieving DCC information I have been trying to get FAQ and related info from www.tttrains.com and get errors (documents not found or denied) Is this a members only site?? I would like information on mobile decoders and the controllers (ie; schematics and software for 16C84s). Thanks John
