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?

Thanks,
