(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).

SAFETY PRECAUTIONS

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

processor. Use them (fig. 1-2, 1-3).

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

instrument.
