Vectored Jump Table
Each of the DOS commands that can be sent to the 1581 via the
serial bus are vectored through indirect jumps in the ROM. The
indirect veaors are located in RAM, so the user can change these
veaors for the purpose of providing a different routine, or massaging
data before passing control to the original routine. Each of these
vectors and their locations are listed in the table 3 :
TABLE 3: Indirect Vector Jump Table
name location description
JIDLE $FF00 Main idle loop. When a Controller command is
completed the IDLE routine is executed. It first
checks to see if there are any more jobs pend
ing in the Job Queue. If so, it executes them. If
not, it sits in the idle loop waiting for some
thing to happen, such as another job being put
into the queue, ATN line going low, disk insert
ed or removed, etc.
