Kevin, saw your post in the CoCoList for Color Computer Enthusiasts, that you have a LR-Tech Super Board just like me. http://qdv.pw/coco/blog/2014/08/05/lr-tech-super-board-2/ I'm in the process of restoring my 1986 Coco-3 setup. Do you happen to have the manual and diskette for this board? Kandur
