Hi!
handful of DOS-based control PC's with obscure I/O hardware (fast-paced low-latency 16bit DC-referenced analog input), and an amazing but abandoned/unmaintained/closed-source modular multi-tasking real-time control system (1 ms scheduler clock)
How about a Linux with proper RT config and drivers, maybe even on a Raspberry-style computer to do I/O with that ancient A/D converter hardware? ;-) Depending on how many channels you need, you could also try something like Red Pitaya: https://redpitaya.com/ Some USB scopes also support 16 bit modes at low sampling rates, with data streaming. But I guess you need real-time reaction and USB is evil :-) Given that Bret has this "use RTC IRQ at 1024 Hz to sort of poll those un-IRQ-able events by hand", you may assume that 1 ms scheduler clock is not horribly hard with GHz CPU clocks even on Raspberry et al. Depending on the hardware, FreeRTOS might help, too.
