====== Save Disk Layout ======

The Rev C and D Z-machine Interpreter Programs (ZIP) save games to disk using a raw block scheme rather than an organized file system.

Each "Save Position" corresponds to a range of tracks on the disk.

During a save, the program workspace RAM is written out as a straight copy from memory to the sectors, in order, in the track range.

Writing a Disk BASIC directory track to a save disk would corrupt the save in position 4.

Writing a Disk BASIC boot track would corrupt the save in position 7.

^  Tracks  ^  Save Position  ^
|  0-4  |  1  |
|  5-9  |  2  |
|  10-14  |  3  |
|  15-19  |  4  |
|  20-24  |  5  |
|  25-29  |  6  |
|  30-34  |  7  |
