+.Os
+.Sh NAME
+.Nm amidisplaycc
+.Nd wscons interface to amiga custom chips drivers
+.Sh SYNOPSIS
+.Cd amidisplaycc0 at mainbus0
+.Cd wsdisplay0 at amidisplaycc0
+.Sh DESCRIPTION
+This device acts as an adapter between the
+.Xr wscons 4
+framework and the Amiga custom chip driver functions.
+It exports the internal
+.Xr wsdisplay 4
+interface and contains the necessary rendering functions to
+operate a text terminal with virtual screens.
+It uses the Amiga abstract graphic driver (grfabs) functions for
+the low-level display management.
+.Pp
+It supports foreground and background color, and the hilite (bold),
+underline, and reverse text attributes.
+.Ss Virtual terminals and screen types
+The number of virtual screens is limited only by
+the available chip memory.
+.Pp
+Each virtual screen can have a different screen type.
+A screen type defines the following things: height and width
+in pixels, number of colors, and font size.
+The supported screen types are listed below.
+.Bl -bullet -offset indent -compact
+.It
+80x64 - display size 640x512 with 8 colors, font size 8x8
+.It
+80x51 - display size 640x510 with 8 colors, font size 8x10
+.It
+80x50 - display size 640x400 with 8 colors, font size 8x8
+.It
+80x40 - display size 640x400 with 8 colors, font size 8x10
+.It
+80x32 - display size 640x512 with 8 colors, font size 8x16
+.It
+80x31 - display size 640x248 with 8 colors, font size 8x8
+.It
+80x25 - display size 640x400 with 8 colors, font size 8x16
+.It
+80x24 - display size 640x192 with 8 colors, font size 8x8
+.It
+default - same as either 80x64 or 80x50, depending on the presence
+of GRF_NTSC and GRF_PAL in the kernel configuration.
+.El
+.Pp
+The grfabs code determines the actual screen mode that is used.
+The config options GRF_NTSC, GRF_PAL, GRF_AGA, etc. determine
+what kind of chipsets/modes are available.
+.Ss Fonts
+Fonts of width 8 and any height are supported.
+Fonts can be compiled into the kernel by specifying "options FONT_[fontname]"
+in the configuration file, or loaded with the
+.Xr wsfontload 8
+utility runtime.
+.Ss X11
+The X11 server works using the
+.Xr wsfb 4
+driver.
+The driver supports 256 and 16 color modes.
