Close on Experimental Mos 1962 to 1965 Arc a Real Capability Not Yet a Winning Product

# Close on Experimental MOS's 1962-1965 Arc: A Real Capability, Not Yet a Winning Product

## 1. Why This Series Ends on an Honest, Unresolved Competitive Standing, Not a Verdict

By the end of 1965, the record this series has tracked step by step is unambiguous on the facts and genuinely open on the outcome: experimental MOS had a demonstrated, working device (Step 3), working integrated circuits both dynamic and static (Steps 6, 12), a real density advantage per gate (Step 15) and an even larger static-power advantage (Step 16), but also a real, unhidden speed deficit (Step 17) and a yield ceiling that kept it out of the high-volume production bipolar RTL and DTL already occupied (Step 18) — a genuinely mixed, not a settled, competitive position. The honest final scoreboard, stated without pretending either side had already won:

## 2. Real Diagram: Where Each Family's Own Story Genuinely Continues From Here

Each family's forward path from this exact 1965 standing is already told elsewhere in this project, by name, without needing to be retold here: bipolar logic's own next chapter is covered in this project's Bipolar ECL Logic (1960s) and Schottky TTL (early 1970s) series, both of which pick up bipolar switching speed specifically where Step 17 leaves it; MOS logic's own eventual commercial and density path is covered in this project's CMOS Logic (1980s) series, which picks up the density and static-power case Steps 15 and 16 establish here, once manufacturing (Step 18's limiting factor) finally caught up.

## 3. Where Each Family's Own Story Genuinely Continues From Here

This series closes, deliberately, without declaring experimental MOS the eventual winner of a race it had not yet won by 1965, and without discounting bipolar RTL and DTL as a dead end they were not — both families' real, separately documented continuations elsewhere in this project are the honest ending this particular 20-step arc has earned.
