Hi again guys,

I've got two more ISA bus questions for the ISA card I am working on. #1)
When I don't want to cause an IRQ, must I tri-state my lines that go to the
IRQ pins or can I just hold it low? #2) How can I cause an IRQ greater than
IRQ7?

Also, It would be great if someone could point me to a web site with info
on the ISA bus.

I appreciate it very much.

BTW The ISA card I am building is a high speed bidirectional 8bit parallel
interface card, specifically designed to interface with digital circuits
that I build, such as PIC based circuits.

Thanks,
Sean
