S., Toronto, Ontario Lines: 27 I'm trying to get a reliable method for determining the event of the floppy disk drive index. I thought that if I opened the ciab.resource and allocated the flag bit of the Interrupt Control Register to my routine, then I could capture this event. However the SetICRVector call fails - a bit of looking around appears to show that the disk.resource has the vector allocated, but it seems that the Interrupt structure pointed to is all zeroes! I could have done something silly, but then I don't have any details on the structure of the ciab.resource. What I'm actually looking to do is to get an indication of the disk's rotation by this method, but perhaps there's another way to do the same thing. Does anyone have any suggestions which could help me past this roadblock?
