c72d612674 Deal with interrupt flags more carefully, and use the correct offset 
for PB500-series SCSI I/O.  While I'm here, update the copyright.

cac1b831e9 - Simplify writes in sbc_drq_intr(). 
- When finished writing, if the SCSI bus has BSY asserted, write another
  byte to the SBC to ensure we get an interrupt.
- Unflag SCSI interrupts on the VIA whenever we clear the interrupts
  on the SBC itself.

057adea27d Apparently the MRG ADB code becomes unstable if we handle via1 interrupts 
properly, so go back to unflagging them all before processing any via1
interrupts.  Perhaps this can be changed back when we get ADB code that
does not rely on the ROMs?

3fb1d834fc Actually clear the interrupt on the RBV. 1996-05-21 00:04:18 +00:00

4b712a8c3f Due to the latching effect of the 6522 (VIA) chip, we need to unflag 
interrupts only after the condition that caused the interrupt has been
cleared.  This is a particular problem with the 5380 SCSI controller,
since the Mac glue logic may raise (e.g.) the SCSI DRQ interrupt a number
of times during the course of a normal transfer.  By waiting to unflag it,
we effectively ignore all but the first.

d048582c60 New grf attachment code, mostly by Jason Thorpe with some cleanup by me. 
This will allow dt and X to work with a generic kernel, rather than
compiling different kernels that attach grf0 to a NuBus adapter or
internal video.
