11/6x Traps Test

This document serves as the maintenance guide and identification for the 11/6x Traps Test program (Product Code: MAINDEC-11-DQKD-A-D), dated March 1977.

Content Highlights:

• Purpose: Verifies the correct operation of all instructions that trigger traps, including overflow conditions, register 6 behaviors, interrupts, reset instructions, and reserved instruction codes.
• Requirements: Requires a standard PDP-11/6x computer and uses memory range 0000 to 22000.
• Operational Details: The program runs in passes (15 iterations after the first quick-verify pass), printing an "END OF PASS" message upon completion. It includes a "TRAPCATCHER" routine to isolate unexpected traps in the vector area.
• Error Handling: Any detected error results in a system halt, allowing the operator to use the program listings to identify the failing subtest via the Program Counter (PC) and test number locations.
