- Bill, if really only want to install a VBL task, that means a task that
- is invoked by the main video boards VBL interrupt and no other special
- things, why don't you use VBLInstall instead of SlotVInstall? This does
- all the job for you: find the main video board and install into that
- irq's queue (not sure if VBLInstall, VBLRemove maintain a special queue,
- but who cares?). It works fine for me on a Quadra 900 and IIsi.

- Hope this helps
