The downline loader downloads the absolute loader to an LSI from
the PDP 11/35 through a user specified TT line. The program then
sends a task image to the absolute loader.

To run the downline loader:

The LSI must first be able to accept an ODT command, This can be done
by halting the LSI, then restarting it.

Run the downline loader from the console.

The downline loader will prompt for the TT line to the LSI, the
downline loader sends the microcode load command to the LSI then
downloads the absolute loader to the LSI.

Once the absolute loader is in the LSI, the downline loader prompts for
the task to be loaded to the LSI, (The task to be loaded must not have a
header) where the downline loader will send the proper information for
loading the task to the absolute loader.

To compile and build the downline loader:

MAC LOAD,LS:LP=LB:[1,1]EXEMC/ML,LOAD
TKB LOAD,MP:LP=LOAD
