1. An installation for the dynamic burn-in testing of a plurality of digital components and digital component assemblies, comprising:
- a personal computer (PC);
a burn-in chamber containing said plurality of digital components and components assemblies under testing;
power supply means connected through said burn-in chamber to said plurality;
means for controlling the operation of said burn-in chamber;
bidirectional digital communication means between said PC computer and said plurality for providing a data highway therebetween;
predetermined reference data characterizing the operation of the respective components and assemblies of components of said plurality being stored for comparison purpose in said PC computer with a related address;
at least one status representative signal being generated by said plurality in relation to a corresponding address for indicating a testing condition;
said bidirectional communication means being controlled by said PC computer to individually and selectively select a status representative signal as an indication of a testing condition at an address relative to one of said digital components and component assemblies in said plurality, and to retrieve the same therethrough;
a corresponding reference data being compared by said PC computer with said selected and retrieved status representative signal for generating an indication of a critical testing condition;
whereby dialoguing through addresses with any of said plurality permits ascertaining with said PC computer the reliability of said digital components and components assemblies through a failure-free burn-in time.

Abstract
An installation for the dynamic burn-in testing of a plurality of digital circuits, and/or microcomputer-controlled circuits, mounted in a burn-in chamber for testing includes a personal computer; power supply for the digital circuits, and a bilateral line of communication between the PC computer and each of the digital circuits; the PC computer interrogating separately, and at will, any of the digital circuits as to their status and capability of changing status while retrieving any indication of a critical testing condition from any digital circuit, to determine a failure-free burn-in time.
