System Error Alert Table

The System Error Alert Table (resource type DSAT, allegedly short for Deep Shit Alert Table) describes startup text and fatal error dialogs for the classic Mac OS.

Specification

See Inside Macintosh: Operating System Utilities, Chapter 2 - System Error Handler, The System Error Alert Table Resource.

ResEdit doesn't support DSAT and only shows a hex editor despite having a custom icon for the resource type.
