Summary
| Description |
English: A 1024-bit core memory module from the Apollo Guidance Computer (AGC). There are 1024 circular ceramic magnets, each one with three wires running through it. A memory bit is set or read by passing current through the wires and changing the polarity of a magnet. This module is approximately 3 inches square.

Pamięć ferrytowa zastosowana w komputerach
modułu księżycowego i
modułu dowodzenia
programu Apollo. W jednym 1024
bitowym module znajdowało się tyleż
magnetycznych rdzeni toroidalnych i przez każdy z nich przechodzily 3 przewody. Bit pamięci był ustawiony, lub odczytany, poprzez przepływ prądu według określonych prodedur przez przewody przechodzące przez rdzeń. Zdjęcie przedstawia jeden moduł widziany z dwóch stron. W jednym komputerze były cztery takie moduły i tworzyły pamięć kasowalną, będącą odpowiednikiem współczesnego
RAM-u. Moduły były w kształcie
kwadratu o boku około 7,5 cm. |
