NAME

     tfb -- PMAG-J and PMAGB-J TX colour unaccelerated 2-D framebuffer

SYNOPSIS

     tfb* at tc? slot ? offset ?
     wsdisplay* at tfb?

DESCRIPTION

     The tfb driver provides support for the PMAG-J and PMAGB-J TX colour framebuffer for the TURBOchannel bus.  The PMAG-J is an 8 bpp or 24 bpp
     colour framebuffer capable of running at a resolution of 1280-by-1024 at 66 Hz.  The PMAGB-J is an 8 bpp or 24 bpp colour framebuffer capable
     of running at a resolution of 1280-by-1024 at 72 Hz.

BUGS

     NetBSD/pmax does not currently support the machine-independent wscons(4) interface and uses a machine-dependent version.

NAME

     tc -- TURBOchannel expansion bus driver

SYNOPSIS

   alpha
     tc* at tcasic?

   pmax
     tc* at mainbus0

DESCRIPTION

     The tc driver provides machine-independent support for the DEC TURBOchannel expansion bus found on all DEC 5000-series machines with MIPS and
     DEC 3000-series with Alpha processors.

     Your system may support additional TURBOchannel devices.  Drivers for TURBOchannel devices not listed here are machine-dependent.	Consult
     your system's intro(4) for additional information.

HARDWARE

     NetBSD includes machine-independent TURBOchannel drivers, sorted by device type and driver name:

	   tcds       PMAZ-DS, PMAZ-FS, PMAZB-AA and PMAZC-AA dual-channel SCSI adapters

   Network interfaces
	   fta	      PMAF-F DEFTA FDDI controller

	   le	      LANCE Ethernet interface

   Frame buffers
	   cfb	      PMAG-B CX colour unaccelerated 2-D framebuffer

	   mfb	      PMAG-A MX monochrome framebuffer

	   px	      PMAG-C PX accelerated graphics boards

	   pxg	      PMAG-D, PMAG-E and PMAG-F PXG accelerated graphics boards

	   sfb	      PMAGB-BA HX colour unaccelerated 2-D framebuffer

	   tfb	      PMAG-J TX 24-bit colour unaccelerated 2-D framebuffer

   Miscellaneous

HISTORY

     The tc driver first appeared in NetBSD 1.1.

BUGS

     The tc driver makes poor use of interrupt priority on the 5000/1xx series systems.
