There are modern-ish industrial motherboards that still have ISA slots and parallel ports, since companies have older industrial automation equipment that they need to keep running and it'd be very expensive to modernize (the old equipment still works so there's not much of a business case for replacing it).
In fact, some motherboards have PCIe, PCI, and ISA all on the same board. For example, this board takes 7th gen Intel Core processors and has an ISA slot: https://elmark-automation.com/shop/msi-ipc/ms-98l9v20 . Unfortunately this one doesn't have a parallel port, but there's others that do.
No guarantee that all ISA devices will work though, since these boards usually use a PCI-to-ISA bridge rather than a true ISA bus.
