The LCD modules used on the front side of the Tyan GS10 and GS12 series
barebones consist of an LCD display by Winstar Display Co. LTD
that is 16 characters wide and 2 lines. high.
To the right of the display there is a 6 button keypad:
4 array buttons and two buttons labeled <literal>C</literal> and <literal>S</literal>.

For more information see the

from the Tyan support page.
Besides a useless old version of LCDproc it contains some
documentation about the panel itself including a PDF specification
of the LCD display by its manufacturer.
