Are there any pros to core logic over transistor based logic?
I recall (from very long ago) a presentation about the Apollo missions. There was a ring that appeared like a spacer or gap filler between the top of stage1 and the bottom of stage2. It got thrown away when stage1 was jettisoned. According to the presentation that "spacer" contained a complete IBM360 which was responsible for launch stability.This was at a time when college students were using punch-cards to run assembler programs on the college IBM360 which was treated like the Holy Grail....R
The instrumentation ring was much further up the stack (just below the LM, I think), was built by IBM, but was only four feet deep, so I doubt it had much of a 360 in it.
I honestly didn't expect this many people to be interested.... if that was then and this is now. What's next I wonder?? In the terms of logic.
I often wondered if it was possible to hear a frame of core memory in operation.However, they usually necessarily operated in noisy (132 column drum line printers, tape drives, washing machine-sized disk drives, air-con...) environments, so I never got the chance to find out.
That reminds me about wearing hearing protection while doing line printer maintenance 95+db and breathing paper dust.
IBM and ICL
Ahhh, core memory, the choice of Apollo Guidance Computer.
It's less vulnerable to cosmic particles than chip, that includes data as it takes magnitudes more energy to change a core bit than a chip bit.
That's why there is a hole in the middle - to let the particles through.
