What do you mean, this bad boy is probably powering a semi-critical government system somewhere, definitely not obsolete.

Edit: not even joking or shitting on it, there's probably a proprietary software system out there somewhere that a contractor was paid to build ages ago. The contractor is out of business or doesn't support it anymore, but it works perfectly in its one little spot. Also an update is gonna cost a quarter of a million dollars.

I've seen disk chart meters at facilities that are 40+ years old and need a new disk chart every so often. You could replace it with a digital meter, but that won't integrate with the rest of the control panel and a third party took over production of the disks 15 years ago. The system works great and it's unlikely to be updated unless they stop making the disk charts.

Edit 2: the correct term is circular chart recorder

I had almost this exact scenario happen with a CNC machine for a very old but profitable niche company. Pain in my ass.

I don't know if it's still there but I once did some work getting a plasma cutter back to operational. OS/2. Not even warp!

Oh it's a pretty solid OS but i mean, damn.

Parallel port hardware key and everything. I do believe in keeping what works working but at some point you gotta let go because you run out of people that can solve problems with it.

Seems like this issue is across a few different industries. I had two CnC machine running software on old PC's with special cards to interface with the drives. One was running in a Dos box while the other was running windows XP. We could never afford any down time so it was fine some old PC's that can still run this stuff.
