+	This handheld organizer/PDA runs on an unknown CR16B SoC.
+	It's probably similar (but not identical) to the one described in glcx.cpp.
+
+	Main board:
+		U1:  Analog Integrations AIC1652CS
+		U2:  8Mbit flash (Toshiba TC58FVT800FT-85)
+		U3:  Hyundai GM76FV18ALLFW70
+		U10: unknown CR16B-based SoC (epoxy blob)
+		U11: National Semiconductor DS14C232CM
+		U12: National Semiconductor LM4882
+		U14: 16Mbit mask ROM (Sharp LH53V16500)
