I started my career working for British Aerospace in 1989. We used VAX/VMS as our development platform (Code was CORAL 66 and then ADA). I spent some time supporting the Sea Harrier flight test operations - so I would have fitted this job perfectly about 28 years ago!). I'd like to say that I'm astonished that modern aircraft still use the 1553 bus, but nothing surprises me when it comes to the use of stone-age tech…

That's insane. A 3d matrix of ferrite rings suspended by wire would seem (to me) somewhat sensitive to vibrations or gforces.

Military gonna military I guess.

Wow. Reminds me of a joke my dad repeated to me many years ago: Software saved the aerospace industry. Every other way of adding cost to an airplane also adds weight. He spent most of his career at Lockheed and Rockwell.

I guess storing all those 1's also adds some weight. It costs on the order of antimatter if you think of it. What's it like, $50 million per 1 billionth of a gram, or so?

The only storage medium I can spontaneously think of where 1s are heavier than 0s is punch cards. I hope that is not the current primary storage method in the aerospace industry.

The same technology was very successfully used to fly to the moon. Cores aren’t so much suspended when they are wholly embedded in epoxy.

No but it’s a good... punch... line haha

I think all engineers with VAX experience are extinct ...or retired.

Hope you're prepared to swallow; I can think of several dozen young engineers across 5 states (California, Indiana, Florida, North Carolina, and New Jersey) with VAX/OpenVMS domain expertise, myself included. Legacy systems with 30-year lifecycles are a thing...they're just not what most of commercial industry is accustomed to supporting. If you think LM would have an issue filling this position internally (for the right price), you'd be mistaken.

But on the other hand core memory is very resilient against EMP and hard radiation :)

I seem to recall something along the lines of large bombers running valves as they were less prone to effects of EMP around nuclear blasts. Not sure if this perhaps something similar?

Well... technically most hard drives should change weight depending on their contents: https://physics.stackexchange.com/questions/31326/is-a-hard-...
