21. The IBM 738 Magnetic Core Storage used on 709 was also a milestone of hybrid technology. 22. Mainframe computers used magnetic core memory, which was too expensive for use in video display terminals. 23. Each bit is temporarily stored in a magnetic core of this register during a memory reference. 24. Designed in 1961, it was a second-generation computer using discrete transistor logic and magnetic core memory. 25. Early A-F models used an magnetic core memory. 26. Industry followed this development closely, adopting the magnetic core memory that expanded the capabilities of computers. 27. The fourteenth 702 was built using magnetic core memory and the others were retrofitted with magnetic core. 28. The GEC 2050 supported up to 64KiB of magnetic core memory in 4KiB, 8KiB and 16KiB modules. 29. These cores used metal tape magnetic cores . 30. This group of states should in turn become the " magnetic core " of a larger unification.
