Re: A86: LCD stuff
In the zilog z80 databook, there is a minumum-system schematic and a few
others for simple computers. One details how you can have multiple
devices produce interrupts. They are arranged in a chain
configuration. When a high-priority device is being served, a
lower-priority device cannot send an interrupt; a higher-priority
device can interrupt over a lower-priority device.
