Just Trying to find out what you mean.No computer interface Well i can and have been running my Trainset alot with my computer through the JMRI program and when i first got into DCC well over 10 years ago i had no plans at all to run anything but DCC,I do own the Digitrax Super Cheif DCS200 and the DB200+ of course over the years i've up-graded to what i've got now.I've not had any major problems with this setup at all.I do find the Digitrax book is a bit confussing to me at times,buy am able to run 1 DC engine at at time if i want to. HaroldIt has not got a computer interface capability, but you can go to a wireless cab easily. also cannot run any locomotives on straight dc. Maybe some of the old hat dcc guys will jump in and explain more.
