Legacy industrial systems and DOS software are impossible to maintain as hardware fails and becomes obsolete

Manufacturing facilities, laboratories, and businesses running critical operations on decades-old DOS applications, CNC machines with ISA cards, and specialized instruments face catastrophic business disruption when aging hardware fails because replacement parts are unavailable, technicians with expertise are retired, and the original software cannot run on modern systems. Current solutions like keeping spare machines in storage are unsustainable, expensive, and only delay the inevitable crisis.
