The Mark IV Loader was developed to accomplish four

objectives:

1. Incorporate the self-starting format described in

DECUS 5/8-27, Bootstrap Loader.

2. Select the reader in use, automatically, without switch

register settings.

3. Enable a newly-prepared binary tape to be checked

prior to loading by calculating the checksum.

4. Reduce the storage requirements for the loader so that

a special program would fit on the last page of memory with

it.
