/*
Casio CTK-2000 keyboard (and related models)
- CTK-2000 (2008)
Basic 61-key model
- CTK-3000
Adds velocity-sensitive keys and pitch wheel
- CTK-2100 (2009)
More flexible sampling feature, lesson buttons double as voice/drum pads
(based on CTK-2000, not 3000)
Main board (M800-MDA1):
IC1: CPU (NEC uPD800468)
Custom chip (ARM-based), built in peripheral controllers & sound generator
LSI2: 16Mbit ROM (OKI MR27T1602L)
Console PCB (M800-CNA):
IC401: LCD controller (Sitronix ST7066U-0A, HD44780 compatible)
