The text is a letter discussing the procurement of transistors for the Minuteman program by Autonetics. It explains the process of establishing second sources for transistors, the costs involved, and the challenges faced in the program due to budget limitations and delays from suppliers. The letter also mentions the evaluation and purchase of transistors from Rheem, as well as the decision to replace the 851M transistor with the 853M transistor from Fairchild for cost-saving reasons.
