Why it matters to a repairer today
[edit | edit source]TechStep is the reason some Apple symptom charts stop at "run the TechStep test": a chart that ends there is not incomplete, it is deferring to a tool most people no longer have. Knowing what TechStep did, and that it needed a product-specific ROM card and cable, tells you when an Apple diagnostic instruction is simply unreachable and the fault has to be chased another way.
What this document does not contain
[edit | edit source]It is a user guide for a tool, not a service manual for any computer. There are no repair procedures for Macintosh hardware in it, no parts lists, no schematics and no component values. It does not include the per-product test descriptions, which were on the individual ROM cards and in their own documentation.
