It also includes a new P66 with LPD 040063,000007: ## (Landing Point Designator) capability, based on an idea of John 040064,000008: ## Young's. Neither of these advanced features were actually flown, 040065,000009: ## but Zerlina was also the birthplace of other big improvements to 040066,000010: ## Luminary including the terrain model and new (Luminary 1E) 040067,000011: ## analog display programs. Zerlina was branched off of Luminary 145, 040068,000012: ## and revision 56 includes all changes up to and including Luminary 040069,000013: ## 183. It is therefore quite close to the Apollo 14 program, 040070,000014: ## Luminary 178, where not modified with new features. 040071,000015: ## Reference: pp. 890-898 040072,000016: ## Assembler: yaYUL 040073,000017: ## Contact: Ron Burkey <info@sandroid.org>. 040074,000018: ## Website: www.ibiblio.org/apollo/index.html 040075,000019: ## Mod history: 2017-07-28 MAS Created from Luminary 210. 040076,000020: ## 2017-08-19 MAS Updated for Zerlina 56. 040077,000021:
