A new take on nonvolatile memory
Well, actually an old one.
A very old one. I present to you a complete, functioning four byte magnetic core memory for the arduino: http://www.corememoryshield.com/report.html http://www.corememoryshield.com/moun...ield-small.jpg Some folks have too much time on their hands... |

Yesteryear's news. You need to read slashdot more often.

When I was in the Air Force I was a Crypto Tech. The KW 26 used magnetic
core memory, we called them bi mags. They were still being used in 1980 http://en.wikipedia.org/wiki/KW-26 |
Interesting.
The history of modern crypto is of interest to me, and I'm a bit surprised that I've never come across the KW26 before. |
KW26??? We had a KG84C and two KY57, and the KY was actually concidered ancient and was there for backwards compatibility with units that weren't upgraded yet.

This is a really nerdy thread. One time pads and all.

When I got out of the service in 1980 I went to work for a pbx manufacturer, and couldnt believe they could run 150 phones in a box half the size of the 1200 baud modem |
