Apparatus using three light emitting diodes (LEDs) and a transistor for indicating whether there is an overtermination undertermination, or power termination of peripheral devices

An apparatus for indicating a termination status of peripheral devices in a computer system, the apparatus comprising:

• a termination data line coupled to a selected peripheral device of the peripheral devices;
• an illumination means, coupled to the termination data line, for providing illumination when the termination data line supplies current to the illumination means, thereby indicating a presence of at least one terminator in the peripheral devices;
• a termination power line coupled to the selected peripheral device;
• an overtermination data line coupled to the selected peripheral device;
• a transistor coupled to the overtermination data line and enabling current to flow when the current supplied to the transistor exceeds a threshold amount corresponding to a presence of more than one terminator in the peripheral devices;
• and
• a second illumination means, coupled to the overtermination data line and to the termination power line, for providing illumination when the termination power line supplies current to the second illumination means and when the transistor enables current to flow to the second illumination means via the overtermination data line, thereby indicating the presence of more than one terminator in the peripheral devices.
