Having also controlled a very large XY Laser system with 8085 code you can understand why I'm puzzled that 1GHz and up 32 ARM computers have so much trouble.
Recent PC's don't have real time capable GPIO ports tied to pins on the motherboard. Some chipsets have had a few GPIO lines that you can toggle at up to ~1MHz but only 6 pins max :(. It is the same for ARM SOC's. If someone added 16 lines of GPIO to their ARM SOC's internal bus that you could toggle at ~1MHz it would not require the use of a PCIe, SPI or Ethernet IO card.
