18b PDP Diagnostics 1. PDP-4 2. PDP-7 2.1 PDP-7 Instruction Test (Maindec 701) The diagnostic must be boot loaded, as it jumps dynamically out of the RIM load process into its own loader. At start, set SR<1:16> to a non-zero value. The diagnostic executes four HLT's as part of initial tests and then runs to completion. Normal HLT is at 2623 (PC = 2624). sim> att -e ptr digital-7-54-m-rim.bin sim> boot ptr HALT instruction, PC: 17670 (AND 17727) sim> d sr 4 ; any even value between 2 and 377776 sim> run 170 HALT instruction, PC: 00171 (CML CMA) sim> ex ac,l AC: 000000 L: 0 sim> c HALT instruction, PC: 00173 (SPA) sim> ex ac,l AC: 777777 L: 1 sim> c HALT instruction, PC: 00176 (SPA) sim> ex ac,l AC: 000000 L: 0 sim> c HALT instruction, PC: 00201 (LAC 4116) sim> ex ac,l AC: 000004 L: 0 sim> c HALT instruction, PC: 02624 (JMP 201) 3.
