Not "missing" but "incorrectly implemented", which is far worse. The bugs I'm talking about only occur under rare circumstances. By now, the Q68 is already debugged well enough to run the QDOS Classic and Minerva operating systems correctly, but not all QL driver and application software. For example TK2 and the pointer environment are not in harmony although they work separately. > 68K instruction set.

I tested all non-commercial 68K cores and found bugs in all of them. TG68 and successors seem better than the rest, but I still haven't found all of it's bugs. > Yep I know the other question is who fixes it all ??? Fixing is relatively easy, the much harder part is to find which instruction had caused a crash or wrong behaviour. > By the sounds of things some one feels volunteered ? > Either way who knows what needs to be fixed ?! Nobody yet. Finding out what else needs to be fixed is the main challenge. Could be only one more instruction. If I had not spent a terrible amount of time for QL-SD I might have found it already.
