Magnetostrictive delay line storage Friden EC-130
Anyone with an old calculator like the Friden EC-130 with a magnetostrictive delay line memory might be struggling to understand how it works.
A nice description, along with much else, is in FV Mayorov's Electronic digital integrating computers. Can't find any for sale, or a download copy, but didn't look that hard. Really just posting this for information, using up the site storage but seemed worth it. |
