Digits = These digits represent the hardware status of
16-21 the PRM. All digits are active in the
transistor/transistor logic (TTL) high state.
The layout of these digits is as follows:
BIT3210
BIT 3: RST - Indicates that the EAI has gone through a
power-up restart. This bit will remain set
until being read by the maintenance
teletypewriter (MTTY) controller.
BIT 2: RUN - Indicates that the associated administrative
module (AM) is executing main store
instructions. This bit is defined as the
