Integrated computer module

An integrated computer module (ICM) for connection to a host connector means in a host assembly, the host assembly containing a DC power supply with DC voltage therefrom coupled to the host connector means, the host assembly connected to or containing a display, the ICM comprising:

• a computing subsystem operable solely when connected to the host assembly, the computing subsystem further comprising:
• a microprocessor;
• a hard disk drive for storing an operating system;
• means for supporting a main memory array;
• means for transferring at least a portion of the operating system to the main memory array;
• means for coupling the microprocessor to the main memory array for executing the operating system;
• means for storing digital display descriptor data in a video memory array;
• and
• a video controller for converting the digital display descriptor data to a time-based display data stream suitable for driving the display;
• module connector means for connecting to the host connector means, the module connector including
• first conductors for coupling the time-based display data stream to the display via the host connector means;
• second conductors for receiving the DC voltage from the DC voltage supply in the host assembly via the host connector means to power the computing subsystem;
• and
• third conductors for exchanging data with an I/O device via the host connector means,
• an EMI enclosure for containing emissions from the computing subsystem;
• and
• a cooling subsystem including a fan powered by the DC voltage received via the host connector means for providing sufficient airflow to maintain the microprocessor within specified thermal limits.
