Re: access of A5 register during Time manager interrupt

Check out Apple Tech. note #180. Also, the Time manager has been
updated so that when it calls your procedure A1 contains the address
of your TMTask record. If your TMTask record is the first item in a
larger struct then you also have the address of that struct. So all
you need to do is save your application's A5 just after the TMTask
record and it will be easy to find.
