Micrologic 1960 Step 17 Catalog Price Part Number

# Publish a Catalog Price and a Part Number: Selling a Function Instead of Negotiating a Contract

## 1. Why a Fixed Price List Is a Claim About Yield, Not Just About Business

This step turns Step 13's cost model into something a customer can read without ever seeing a wafer: a published catalog price per part number, available to any buyer who places an order, rather than a figure negotiated contract by contract the way most of Step 9's military business had been priced. Publishing one number for one part type is only possible once Step 7's whole-chip yield and Step 13's cost-per-good-die curve are both stable enough that this series can predict, with reasonable confidence, how many good dies a given wafer run will produce — a volatile or poorly characterized yield would force the kind of case-by-case pricing a defense contract tolerates but a catalog buyer never would.

$$P_{\text{catalog}} = C_{\text{good die}} \cdot (1 + m), \qquad \sigma_{C_{\text{good die}}} \ll C_{\text{good die}}$$

where $P_{\text{catalog}}$ is the published list price, $m$ a margin fixed in advance for every unit of that part number, and the right-hand inequality states that the run-to-run variance in cost per good die has to be small relative to the cost itself — otherwise a fixed margin on an unpredictable cost would either lose money on bad runs or overcharge on good ones, and a catalog cannot absorb either outcome quietly the way a negotiated contract can.

A Published Price Only Works If Cost Holds Still negotiated contract pricing versus a fixed catalog number, run to run wafer run, in sequence → cost per good die catalog price, fixed above the tight band a stable cost band is what makes one printed number honest, run after run

## 2. Real Diagram: A Part Number Replaces a Negotiation

A defense contract priced Step 9's qualified parts case by case, with specification, volume, and schedule all negotiated together. A catalog part number collapses all of that into one line a buyer can find in a published list, order against, and receive without any conversation beyond the order itself.

Negotiated Contract Versus Catalog Order what a buyer has to do to get a part, before and after this step DEFENSE CONTRACT PATH negotiate specification negotiate volume and schedule negotiate price last CATALOG PATH, THIS STEP read the part number and price, place the order this collapses three negotiations into one line in a published list

## 3. Why Step 15's Non-Military Buyers Needed This Step Before They Could Place an Order

The computer manufacturers and instrumentation builders Step 15 described would not negotiate a defense-style contract for a few logic gates the way a missile program would — they needed a part number and a price they could read, compare, and order the same way they ordered any other component on their bill of materials. A catalog is what makes a chip, as opposed to a qualified military system component, something a purchasing department outside aerospace can actually buy without a specification review.

Step 17 does not change anything about the chip itself; it changes the chip's relationship to a buyer, from a negotiated deliverable into an ordinary stocked part — the last piece of business infrastructure this series needed before Step 15's broader market could actually reach for it.
