  Just use iteconfig to set the display height to 200.  That will use
the non-interlaced NTSC display (and a height of 256 should give a
non-interlaced PAL display - but with a 32 line display).  The kernel
source can also be modified to make that the default (or the kernel
image itself can be binpatched).

  On another note, I don't think anyone has written a driver for the
Octagon SCSI.  I don't remember if I've seen which SCSI chip the Octagon
uses. If it uses one of the chips that NetBSD currently supports,
getting it to work as a simple programmed I/O driver should be
relatively easy if the information about addressing the SCSI chip is
available or can be determined.
