(2) Core memory. The memory size in a core-based processor is 64k Words. The
word length is 17 bits, consisting of 16 data bits and an odd parity bit. The A16 Internal
Memory Control/Remote Memory Control (lMC/RMC) Controller PCB controls both
internal and external memory. Core memory in non-volatile and retains data integrity for
an indefinite duration, even with loss of prime power to the processor.
Core memory size can be increased in 32k Word increments; however, increase above the
already contained 64k Words requires the addition of, and interfacing of, one or more
remote memory chassis (through J6).
The processor is a heavy piece of equipment. Three technicians are employed when
moving the unit. Handles are provided on the processor as an aid when moving the
A periodic review of safety precautions in TB 385-4, Safety Precautions for Maintenance
of Electrical/Electronic Equipment, is recommended. When the equipment is operated with
covers removed, DO NOT TOUCH exposed connections or components. MAKE CERTAIN
you are not grounded when making connections or adjusting components inside the test
