Core memory was interesting in a lot of ways. It was horribly slow by today's standards and likewise the density was abysmal by comparison with any kind of solid state RAM. Reading it destroys the stored memory, so the controller always had to write the value back. On the other hand, real core memory is non-volatile, so you could power the machine down and when you next turned it on, the contents of main store would be what they were when you shut it down.
I often used that to advantage when repairing computers. I could load diagnostics into a memory board in a good computer and then move the board to the computer I was working on. ______________________________________________________________________ Post your free ad now! http://personals.yahoo.ca
