NAME
     tcx - accelerated 8/24-bit color frame buffer

SYNOPSIS
     tcx* at sbus? slot ? offset ?

DESCRIPTION
     The tcx is a memory based color frame buffer, with graphics acceleration
     and overlay capabilities. Its control registers, colour lookup table and
     pixel memory can be mapped into a user process address space by using the
     mmap(2) system call. The tcx driver supports the minimal ioctl's needed
     to run X(1), and can be operated in cgthree(4) emulation mode.
