:help: I need further service manuals of the first Casiotone music keyboards and synths. I don't mean CZ, SK or CTK which is well online, but the really old semi-analog things like these:
- CT-201
- CT-401
- CT_701
- CT-6000
- Symphonytron 8000
- HT-3000
- HT-6000
- SK-200
- PT keyboards
- VL-5
- MT keyboards (like MT-200, MT-800, MT-820)
I want to contribute to a sound hardware research and documentation project (perhaps resulting in an open source software synthesizer).
(I have already uploaded the 1000p and MT-65/MT-100 service manuals to ElektroTanya. Most other schematics I have are anyway here, but I may provide some additional proms and eproms.)
