Wait, core as in magnetic core memory? Was there any advantage to still using it as late as the late 70s? Or was it an older mainframe? But in any case, your comment made me realize how little I know about that time period even if I'm super interested in it. Thanks for sharing!
- Taniwha 4y agoSemiconductor memory was really really expensive until it hit the 16-64kbit/chip level and then it had a bit of a crisis because they suddenly all went a bit flaky (turned out to be alpha particles in the ceramic packages) - that was around about 1980 - at the time it was a bit of a mystery and people were wondering if memory would be able to get any denser and still be reliuable. I think we bought our first 'big' machine with semiconductor memory around then (a Vax 11/780)
