002315,000004: ## Purpose: A log section of Zerlina 56, the final revision of
002316,000005: ## Don Eyles's offline development program for the variable
002317,000006: ## guidance period servicer. It also includes a new P66 with LPD
002318,000007: ## (Landing Point Designator) capability, based on an idea of John
002319,000008: ## Young's. Neither of these advanced features were actually flown,
002320,000009: ## but Zerlina was also the birthplace of other big improvements to
002321,000010: ## Luminary including the terrain model and new (Luminary 1E)
002322,000011: ## analog display programs. Zerlina was branched off of Luminary 145,
002323,000012: ## and revision 56 includes all changes up to and including Luminary
002324,000013: ## 183. It is therefore quite close to the Apollo 14 program,
002325,000014: ## Luminary 178, where not modified with new features.
002326,000015: ## Reference: pp. 55-61

002329,000018: ## Website: www.ibiblio.org/apollo/index.html
002330,000019: ## Mod history: 2017-07-28 MAS Created from Luminary 210.
002331,000020: ## 2017-08-12 MAS Updated for Zerlina 56 (no changes).
