3 Processor Device Simulations
An HP-family computer consists of the following subsystems:
• a 2114, 2115, 2116, 2100, or 1000 M/E/F-Series Central Processing Unit
• an optional 12578A/12607B/12895A DMA Controller or 12897B DCPC Controller
• an optional 12581A/12892B Memory Protect
• an optional 12731A Memory Expansion Module
3.1 Central Processing Unit
The HP computer Central Processing Unit contains the machine-instruction execution unit and main memory. CPU
options specify the memory size, installed firmware, and simulation configuration. The CPU is configured with
commands of the form:
SET {-F} CPU <option>
Device options that may be specified are:
