On the DMA U36, FDINT and HDINT are indeed input signals and combel
outputs DSKIRQ (which becomes XDISKINT in other parts of the schematic).
DSKIRQ is a combination of these 2 input signals.
But I don't see where HDINT is coming from, I guess it's the ASCI's irq ?
After getting https://www.dev-docs.org/ up and running again -- more or
less :-( -- I could look it up in the schematic: HDINT comes from the
53C80 SCSI controller. (Search for "Atari Falcon030 Schematic (Rev G)"
on dev-docs; it's U7 on page 8.)
Ah yes, thank, the page is slightly truncated on the left and the label
was not entirely visible.
But then I don't see the ASCI IRQ line that is combined with FDC IRQ on
STF for example. Do you see it ?
