- The 68 F-line was a 'spurious interrupt' vector until Omega-SANE

- In your case you have a Mac II, so I would personally suspect something
- more strange like writing code that overrides the low memory vectors
- with bogus values. Check if you by mistake write into low memory
- inside your program. Anyway, that'a guess. If you use Think C 5.0.3
- it should have the new debugger that should know about the F-line
- use.
