How Verbs and Nouns Got Apollo to the Moon


How Verbs and Nouns Got Apollo to the Moon

The Apollo targeting team did a lot with little, but the idea that the mobile phone has more power than computers is a little off. Yes, a smartphone may contain more information, but it did not exactly do the software to reach the moon. However, the Apollo computer orientation (AGC) relatively low, although it does not have a keyboard and a monitor as its office, spoke in colloquial language we use everyday names and verbs.

An all-moon mission was managed by Apollo’s guidance team to check the alignment of the guiding platform and fire engines. In total, it was about 10 500 hits to get to the moon back and forth, and each one has entered the “screen and keyboard” of the computer interface orientation, affectionately called the DKSY (pronounced “say-key” ). There were three on board – two on the command module and the lunar module – and all three proposed information simply and concisely in digital coded messages or by a series of semaphores.

There were ten warning lights that the crew could use to alert the crew of a problem:

• acty COMP: the computer has become a program.

• cleaned before: the plant data was received.

• TEMP: stable platform temperature was out of tolerance.

• NO ATT: Inertial subsystem could not provide a reference attitude.

• axle lock: the universal middle angle was above 70 degrees.

• STBY: The computer was in standby mode.

• PROG: Turns on when the computer is waiting for the input of additional information by the computer to complete the program.

• REL RELEASE: On when the needs of the DSKY control computer to complete a program. Sometimes the information on the screen can be “buried” under other routines or a priority interruption. The crew could press the REL KEY button to release the requérant150 keyboard program. When the semaphore was put REL KEY, this marked the press crew.

• Restart: Lights up when the system was in the reboot program. It was the light that continued to occur during the landing of Apollo 11.

• OPR ERR: Lights up when the computer detects a keyboard error.

• TRACKER: Lights when one of the optical coupling units is faulty.

The DSKY in the lunar module, which had the only task of landing on the Moon, had three additional lights: No DAP, ALT, and VEL. It was warnings about built-in digital autopilot failures and avoid readings of altitude and speed outside the predetermined limits when landing on the progressing moon.

The main DSKY astronaut keys were used to enter commands, were the key verbs, names, plus, minus, numbers and a handful of control buttons. These keys can display different types of information:

• PROG was a two-digit display showing the number of the computer program currently running.

• VERB was a two-digit screen of the introduced verb number (the verb-name system is discussed later).

• Show name was a nominal two-digit name entered.

• Three digital screens to five figures, showing numbers in decimal or octal (base eight).
