I thought I'd said that--"dissipating heat" implies that local
heating from cores was dissipated into the oil bath. But maybe I
wasn't clear on that aspect--my apologies. I suspect that fluorinert
might be a better choice today.
I suspect Ian is referring to the fact that the oil in the 709T/7090 was't just
cooled, it was also heated as necessary to maintain a near-constant temperature that was
selected to optimize the performance of the magnetic material in the core stack.
I'm a bit surprised that no one picked up on the
mention of the
broomstick.
Well, broomstick plus magnet, right? Gotta be able to pick up the blown-apart cores.
Those were the days, when computing carried the risk of delightfully catastrophic failures
