I will be building a Francis board soon, so will find out if this works O.K. with it too. I don't see why noth though. <<>> > >douglee@becker Have all the problems with geting LUCAS to work with Microbotics Starboard been fixed? I would like to build/buy one, but I have a Starboard with 2 Meg and a SCSI module installed. If they have been, who should be contacted for the latest plans & parts ? Also, is this a resonable progect for a novice? I have never built anything with lsi chips on it, though I am fairly good with a soldering iron. Assuming I have nothing else but a soldering iron, and only a rudimentry knowledge of electronics, what would I have to read+learn+buy to put a LUCAS board together and get it to run with my Amiga+Starboard ? Thanks in advance, Charles Hymes
