| 1. | By 1954, those unreliable methods were mostly replaced by magnetic core memory.
|
| 2. | The memory was changed from magnetic core to semiconductor with battery backup.
|
| 3. | The DATANET-30 used magnetic core memory with a cycle time of 6.94 ?s.
|
| 4. | Another is for the ornamental design of a Transformer magnetic core.
|
| 5. | The name has remained long after magnetic core technology became obsolete.
|
| 6. | The magnetic amplifiers were based on tiny magnetic cores with two wire windings.
|
| 7. | Both were made obsolete by the invention of magnetic core memory.
|
| 8. | Two key inventions led to the development of magnetic core memory in 1951.
|
| 9. | An Wang was an important contributor to the development of magnetic core memory.
|
| 10. | The original system had 2k of non-volatile magnetic core memory.
