Tell me how is someone supposedly going to hack a terminal, they can't gain physical access to? The security is not in the storage medium, or the age of the system. It's in the physical location of the terminal.
Well, this topic is another one of those "click bait non-starters". The person who released this report or what ever the f*** you want to call it, obviously knows squat about electronics, computers, or anything else related to the topic. The trouble is, John Q. Public is an hysterical imbecile, who knows less about squat, let alone the quirks and protocols of maintaining aging gear. Then too, we have a bunch of "ending is better than mending" knot heads, who genuinely have been conditioned to not be able to live without a thinner phone or a lighter tablets, along with "whiter whites", and refrigerators that think for them.
Reasonably speaking, as long as this gear is not vacuum tube based, a lot of it isn't any functionally older than the day it was commissioned. Now this sh!t isn't crammed into a tiny box that would cause heating problems, and none of it needs to fit in Hillary Clinton's purse. Nor is space or scale a problem. The air gap and armed. guards aren't going to let some 15 year old use it to download porn, or run some crap script he or she bought somewhere on the TOR network. Those guards are trained to shot to kill, another strong deterrent.
As for the programming language, if it is "FORmula TRANslation", it's the perfect language to resolve targeting problems, which are nothing but formulas for speed distance, angle of flight, and geo-positioning.
As for the hardware, there are just a few critical issues. First, any electrolytic capacitor in the system needs to be replaced, along with any heat bathed, or head producing modules. I.E. VRM modules. Fans could be renewed, along with drive motors and heads for tape or floppy disc read/record. The transistor components could ostensibly last forever, assuming the cases don't disintegrate from old age. BUT, the conditions the equipment operates in, is far, far, better controlled then the average modern home by a long shot.
Even if the stuff is shot, the smartest way to go, would be to replace it with exactly the same equipment which is there now. We have better plastics now for wire coverings than we ever did 50 years ago. Ostensibly material advancements across the board. And face it, we have less nuclear warheads than we did during the cold was, so I suppose that could mean we need less computing power to control the fleet,. FWIW , unleashing a multi megaton thermonuclear warhead, doesn't require lasing a target such as a tank or a two story apartment. Two miles away would basically be a direct hit. So, the old saying, "close only counts in horseshoes and hand grenades, needs to be updated to include atomic bombs! (y)
Ask yourself, would you rather have floppy discs which have survived 50 years, or a bunch of brand new sh!t a** Seagate 3TB HDDs, which it seems by the reviews, crap out after the 2 year warranty expires..
And face it, you don't actually need as much storage, (AFAIK, a guess) than a single Google data center
