Old core memory system.

Core temp was a big issue even in commercial environments. You didn't see it temp but you would see core [driver] current. My 360/50 panel has the ability to monitor and adjust in real time the core current. Military or extreme environment core was a bitch to keep working. I worked on a system designed to go in a Army tank and I came in late but remember we had to test the system from -55 F to 155 F, and the core was the biggest trouble maker. -pete On Sat, May 5, 2018 at 9:50 AM, Jules Richardson via cctalk < cctalk at classiccmp.org> wrote: > On 05/05/2018 04:57 AM, Mattis Lind via cctalk wrote: > >> It could be flight control related since it is aviation museum that >> currently have it. >> > Hmm, 'stack heater' caught my eye...
