Hi Davide, > Just for curiosity (for sure discussed many times in the past): why the > QL-SD interface is not compatible with GD or SGC?
You mean GC, not GD I assume. It is mainly a SGC issue, some users reported GC to work with QL-SD. The slewrate of some SGC signals is too fast for the QL motherboard. As a consequence, the SGC produces illegal electrical signals inside the QL, which can cause QL-SD to malfunction. Because the disturbances have a high frequency, they are not "seen" by the slow components of the QL itself, but only by the much faster QL-SD. My guess is that replacing the QL motherboard could fix this issue. Unfortunately, I have no Aurora system to try. Peter _______________________________________________ QL-Users Mailing List
