Micrologic 1960 Step 15 Early Adopters Computer Instrumentation

# Reach the Early Computer Industry and Instrumentation Market Beyond Minuteman and Apollo: Who Bought This Chip Without a Military Contract

## 1. Why a Part Qualified for a Missile Also Sold to a Laboratory Bench

This step follows Micrologic past the two named government programs Step 9's qualification covered and into the customers who placed an order with no military specification attached at all: computer manufacturers exploring transistorized digital logic for commercial machines, and instrumentation builders who needed small, reliable counting and switching functions for test equipment. Neither of these buyers needed a part proven against launch vibration or space radiation; what they needed was exactly what Step 13's cost model made possible once volume rose past the smallest military orders — a logic function in one small package, cheaper and more reliable than the same function built from individually soldered discrete transistors and resistors on a circuit board.

where a discrete board's cost grows with both its component count and the number of hand-soldered joints connecting them, each joint a possible failure Step 9's reliability testing would never have accepted from a military part, while a Micrologic chip's cost is the single number Step 13 derived — and once that single number fell below the discrete alternative's sum, instrumentation and computer buyers who had never asked about Minuteman or Apollo had their own, purely economic reason to switch.

## 2. Real Diagram: A Discrete Board Loses to One Package on Both Space and Joints

A logic function built from discrete parts occupies board area proportional to its component count and accumulates a solder joint at every connection; the same function on one Micrologic die occupies one socket and carries the joint count down to whatever the flat-pack's own leads require, a fixed number set by the package Step 8 already qualified.

## 3. Why a Commercial Market Did Not Need Step 9's Qualification to Want This Chip

Minuteman and Apollo bought this chip because nothing else could pass their specification; the computer industry and instrumentation buyers this step describes bought the same chip for an entirely different, purely economic reason that owed nothing to a military tolerance band. A computer manufacturer weighing transistorized digital logic cared about packing more function into less board area at a lower total cost, and an instrumentation builder cared about a counting or switching stage that would not need field rework after a few thousand hours of bench use — both needs that Step 13's cost curve and this series' own reliability record, independent of Step 9's specific aerospace requirements, already satisfied.

Step 15 does not describe a different chip reaching a different customer; it describes the same chip Step 9 qualified, discovered by a second, much larger market for reasons that had nothing to do with a launch vehicle at all — proof, ahead of Step 20's closing argument, that the commercial case for this technology never depended on its military one.
