“How many IRQ’s does the Aark 24 use? Which IRQ‘s will it occupy and will it interfere with my other peripherals?”
One of the cool things about the Aark 24 is that it does not use an IRQ. However Windows always assigns an IRQ automatically to the Aark 24. The Aark 24 does not use the IRQ that Windows assign to it so that IRQ can be used (shared) by another peripheral. It may move other peripherals to other IRQ’s, but it shouldn’t make them behave any differently on your PC.
