1. A computerized diagnostic system for providing diagnostic output relating to a predetermined machine, the computerized diagnostic system comprising: a portable machine having unique operating characteristics; a microprocessor-based electronic control means for controlling the portable machine, the electronic control means having a RAM type memory and a ROM type memory; means for electronically providing raw, operating parameters of the portable machine to the electronic control means; means for storing, in the RAM of the electronic control means, the raw operating parameters of the portable machine; an array of pointers for facilitating the location of predetermined RAM addresses of raw machine operating parameters, the predetermined RAM addresses correlating to a unique set of raw machine operating parameters which are known to be useful in the monitoring and diagnosis of the portable machine; a remote, microprocessor-based computer means for diagnosing and monitoring the electronically controlled machine; means for establishing communication between the electronic control means and the remote computer means; reference means, stored in a memory of the remote computer means, for interpreting the raw, predetermined machine operating parameters known to be useful in the monitoring and diagnosis of the machine; means for retrieving, into the memory of the remote computer means, the raw, predetermined machine operating parameters in a predetermined, time stamped order to facilitate identification thereof; and means for displaying user friendly symbols, which correlate to the raw machine operating parameters, in function-specific groupings which permit the predetermined diagnostic output to be displayed in a machine operational sequence to reveal a complete and comprehensible snapshot of the machine operating parameters permitting the determination of normal and abnormal machine operation.
