PROTOTYPE Apple TechStep
(Ships fast and free from the USA!)
You are purchasing a prototype Apple TechStep diagnostic tool.  A friend who was an Apple engineer on the TechStep development team gave it to me in the early ‘90s.  It includes everything included in the pictures; nothing more, nothing less.  While I do not guarantee its functionality, I will tell you that it works, as I have used it many times to diagnose different machines.  Please inspect my detailed pictures and feel free to ask any questions.
Trackable and insured shipping via USPS Priority Mail is FREE.
