I'm sorry, I rather new to this echo and hence am not too familiar with what you are asking (ie if this is in clarification to a previous question). However if you are looking for a nifty little chip to take care of interrupts, you may want to examine the Z80-PIO, it's a little strange but does have the capability to monitor several sources for certain conditions and generate interrupts accordingly. That is if you can interface it. I'm a Motorola person myself, so I don't really know. :-)

 JAG> Thanks a lot in advance.
Yer welcome, hope it helped.
