3000 owners have made plans for many years to leave the platform. The strategies do take a considerable while to evolve into tactics, though. The planning stage is easy to get stopped at, like an elevator jammed up at a floor.
For example, take a company like the one in the deep South, using HP 3000s and manufacturing copper wire and cable. The manager would rather not name his employer and so we won't, but we can say the 3000 is dug in and has been difficult to mothball.
In fact, the only immediate replacement at this corporation might be its storage devices. The datacenter employs a VA7410 array.
We do have to replace a drive now and then, but there hasn't been any problem getting used replacements, and we haven't suffered any data loss. I think if we were planning to stay with MPE for the long term, we might look for something newer, but we are planning to migrate. In fact we planned to be on a new platform by now, but you know how that goes.
More companies than you'd imagine know how that goes in 2018. We're nearing the end of the second decade of what we once called the Transition Era. The final mile of that journey can be the slowest, like the path of the postman who must carry the mail on foot through urban neighborthoods.
