Random DCA Test

The document provides a comprehensive overview of the MAINDEC-8E-08GC-D diagnostic program, designed to verify the DCA instruction set on the PDP-8/E.

Key features include: * Operation: Uses a random number generator to create test scenarios, specifically targetting address and operand selection for the DCA instruction. * Execution: Operates in a designated memory test area (locations 0410 to 7600), ensuring non-interference with system diagnostics. * Error Handling: Features sophisticated error logging that identifies the specific address, operand, and location involved in a failure. It includes a specific mode for scope loop testing for troubleshooting. * Control: Provides detailed instructions on switch register settings for custom control, such as bypassing or halting after errors.
