- Mephisto Sensors Board emulation
- Mephisto Display Modul emulation
+Hegener + Glaser Mephisto Sensors Board, for modular chesscomputers
+- Modular
+- Muenchen
+- Exclusive
+
+This device can also apply to non-modular boards if I/O is similar
+Bavaria board is not emulated here, additional handlers for it are in the driver.
