These source-code files were transcribed from a printout in Don Eyles's personal
collection, scanned by archive.org, and financially sponsored by Linden Sims.
A team of volunteers performed the transcription and proof-reading. The scanned
page images are available at
the Virtual AGC Project website, as well as higher-quality (but much larger)
images at
the Virtual AGC Project's collection in the Internet Archive. Report any problems by creating
"issues" at
the Virtual AGC Project's GitHub Repository. Notations on the program listing read, in part: GAP: ASSEMBLE REVISION 56 OF AGC PROGRAM ZERLINA BY ZOROASTER 9:12 OCT. 21,1970Note that the date is the date of the printout, not the date of the program revision. |

059672,000004: ## Purpose: A log section of Zerlina 56, the final revision of
059673,000005: ## Don Eyles's offline development program for the variable
059674,000006: ## guidance period servicer. It also includes a new P66 with LPD
059675,000007: ## (Landing Point Designator) capability, based on an idea of John
059676,000008: ## Young's. Neither of these advanced features were actually flown,
059677,000009: ## but Zerlina was also the birthplace of other big improvements to
059678,000010: ## Luminary including the terrain model and new (Luminary 1E)
059679,000011: ## analog display programs. Zerlina was branched off of Luminary 145,
059680,000012: ## and revision 56 includes all changes up to and including Luminary
059681,000013: ## 183. It is therefore quite close to the Apollo 14 program,
059682,000014: ## Luminary 178, where not modified with new features.
059683,000015: ## Reference: pp. 1362-1368

059687,000019: ## Mod history: 2017-07-28 MAS Created from Luminary 210.
059688,000020: ## 2017-08-29 MAS Updated for Zerlina 56.
