The Honeywell 10002/1/2 central processor unit (CPU) is the core component of each FSC system, responsible for controlling all system operations. The module features a key switch on the front panel, serving as a hardware reset for the processor. The key switch has two positions:

• Vertical: Running
• Horizontal: Stop (CPU Reset)

The CPU module is equipped with battery backup circuits for RAM memory, allowing backup power supply from the batteries located on the diagnostic and battery module (DBM, 10006/1/1 or 10006/2/.) or single bus driver (SBD, 10007/1/1).

Memory

The 10002/1/2 CPU module contains the following on-board memory:

• 128 Kbytes of RAM for system and application variables (including all I/O, markers, counters, timers, and up to 7 Kbytes for registers).
• 128 Kbytes of RAM available for use as application RAM (depending on jumper positions).

The 128 Kbytes of application RAM can run small application programs in RAM without the need for additional memory circuits in the dual in-line (DIL) sockets. A separate memory print (10002/A/1) is placed in the connector strips on the 10002/1/2 module, accommodating surface-mounted EPROMs containing the system program. It also has four sockets for application program memory (EPROMs or RAM).

Reprogramming the surface-mounted EPROMs is possible using the 07170/1/1 FSC EPROM programmer with a 07170/A/1 adapter module. The EPROMs can be erased by placing the 10002/A/1 module in an EPROM eraser (UV light source).
