It's kinda awesome, that the literal title of the manual is "Exploitation manual" :)
Logical "1" - 20-60mV Logical "0" - 10mV (not more)

Core memory is non-volatile. If you hooked it up to a computer, you could read out what was written into it. Theoretically. NASA recovered the Challenger's core memory out of the ocean and was able to read it out months after the disaster. "On March 19, 1986, NASA announced that four of five Challenger General Purpose Computers (GPC) had been recovered from the Atlantic and moved to the IBM Federal Systems Division f…
I was going to respond that to the parent, but you beat me :) Imagine hooking up and figuring out you can read it? Even better, imagine it contains nuke launch codes (in the best soviet-from-secret-agent-movie tradition)?!
The SPARCClassic and its stack of disks is still quite impressive.
That's crazy, you can see it's handmade. I wonder if it still works?
Might be fun to hook it up to an Arduino and see if you could read/write. I imagine it needs its own power supply.

You can't really "measure" or double-blind test how well this thing kills people. Only if you have well developed taste can you appreciate the finer details, the warmth, the clarity, the fidelity.

There are reports of ground crews for MiG-25's drinking the hydraulic fluid for the planes, which was apparently based on ethanol. Truly an aircraft for those with a discerning palette.

I obsess over these pedantic differences too and I'm repeatedly pitches 3.5" floppies onto your lawn NERD SHAME EDIT: It's been a while... 3.5"
What must really drive you nuts about your 3.5" floppies are the fact that they are not 1.44 MB, or 1.44 MiB, or anything else that resembles 1.44 x some factor. They are actualy 1000 x 1024 x 1440 bytes (so 1440 KiB). The 1.44 on them is derived from a mixture of SI and Binary units.
I think you accidentally included a "1000 x".

Rust is still a problem with those little ferrite rings, though. Depending on the environment you maintain for this device, it can actually be pretty delicate. I have some old (~25 year-old) electric motors, where the magnetic properties of the bigger ferrite rings have been degraded by rust. I guess it probably depends of the quality of the piece. This means there could be one tiny rusty ring in one of the center pl…
Since it's "solid state" (none of those parts move, do they?), I don't see why you need to leave it exposed to the outside air. Could you just cast the whole thing in plastic, or would it overheat? Maybe a mineral-oil bath?

I suspect it's just the standard (for the time) term in Russian for what would be called a deployment manual and/or service manual in English. I've worked with old French documents titled "Manuel d'exploitation" that are essentially how to make the device/software work in production (installation/in use/maintenance).
