@SecurityWriter @barubary Yeah, when it's just the hardware/machine interface that's outdated, rolling your own can be plausible.
I have one client who uses an advanced robotic HID, though, and that thing will only run with its own drivers and they only run in very specific situations.
In effect, we're paying for another company's tech debt.
Could we make a modern version of the hardware? Well, none of us are robotics engineers, so to do so, we'd essentially have to hire a whole new team to create an entirely new product from the ground-up. That might technically be a "won't" but most businesses simply can't afford to pivot that hard and survive.
