I posted that after dreaming for almost 50 years I have successfully run a loco on dcc! I don't know if changing to mega instead of uno, or lightly holding a finger on the loco during R/W solved the days of consternation (something i think i read here, so a big TY 2 U Guys)watchIing inanimate locos while i fiddled with code and jumpers. The wife and I have pretty much settled on, "The Saint Hog to Spinnaker Sheet and Anchor Rode Railway". My final config for the mega and velleman was signal main a 12 to dir A 7 and signal main prog 2 to dir B 13 The burning part is that after living on this earth for a few hours I somehow mashed the velleman down and the less arched to the mega SUB input and caused quite a volcano of molten bits. I didn't cry though, lol. I'll be off to tanner electronics at lunch to grab another! Regards, Nels
