# mac68k screen

The unit at [drv/mac68k/screen.fs] implements a [gr/buf] for all the supported
mac68k models. There is no initialization required, the "screen" variable from
[gr/buf] is set when the unit is loaded.

Initialization depends on particular Mac models and these models are
auto-detected by the unit so that proper initialization ensues.

Supported models are:

* Powerbook 520 (2-bit grayscale, 640x480)
