An example of an ISA interface card with extremely limited interrupt selection options, a common problem on PC ISA interfaces. Kouwell KW-524J dual serial, dual parallel port, 8-bit ISA, manufactured in 1992: * Serial 1: IRQ 3/4/9 * Serial 2: IRQ 3/4/9 * Parallel 1: IRQ 5/7 * Parallel 2: IRQ 5/7 (There is no technical reason why 3,4,5,7,9 cannot all be selectable choices for each port.)
