|
| 12. | Core, was the term for the core memory systems common to the PDP-11.
|
| 13. | They were replaced with other technologies, notably core memory, starting in the 1950s.
|
| 14. | Both were made obsolete by the invention of magnetic core memory.
|
| 15. | Diagnosing hardware problems in core memory required time-consuming diagnostic programs to be run.
|
| 16. | The NonStop II also replaced core memory with battery-backed DRAM memory.
|
| 17. | The entire core memory was in the IBM 1625 memory unit.
|
| 18. | Two key inventions led to the development of magnetic core memory in 1951.
