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).
