briggs 2412580d6a Forgot a declaration in last change to esp.c. 1997-11-25 03:54:56 +00:00
briggs fde9e5e6c3 A first cut at faster SCSI for non-AV quadras. Could probably perform better,
but is a marked improvement.  This takes advantage of a pseudo-DMA hardware
hack of Apple's that exposes a 16-bit register that the Apple-designed
memory controller acts like a DMA controller and handshakes into or out
of the FIFO.  Wierd.

briggs 868344972a mac68k-specific portion of m.i. ncr53c9x driver. 1997-02-27 14:06:25 +00:00
briggs 7685e9d70b Improve reliability on my Q700, at least. Was getting the occasional
glitch--an extra byte on occasion.

briggs 50c2da8f27 Interrupt-driven, but slow, NCR 53c96 driver for the 040-based macs. Contains
some guesses for the machines that have two of these buggers (I don't have
such a machine).  This driver is a copy of the sparc/alpha esp with a
minimum of changes--after we get it performing a bit more respectably,
we should see about re-normalizing the sources.
