I have uploaded 2 service manuals of vintage Casio synthesizers. One is for Casiotone 1000p. The other is combined for the electronically similar Casio MT-65, MT-68, MT100 and CT-405. I hope this can help people to repair their Casio synths and upgrade missing functions in MT-65 related keyboard variants.

Üdv! Új vagyok itt, és rögtön egy kéréssel fordulok hozzátok. Nemsokára veszek egy hibás, témában megjelölt projectort, szükségem lenne hozzá egy service manual-ra, esetleg valaki tudna nekem segíteni ezügyben? Interneten csak fizetőset találtam, ha nem lesz más, akkor megveszem. Előre is köszönöm!

Hi everyone.
I'm trying do fix a door operator (Kone Uniswing Operator) for a public association which takes care of disabled people.
It mainly consist in a dc motor powered through a full H bridge and controlled by a single chip 16 bit microcomputer (M16C/62P family)
First investigations show that the motor is ok, power rails are clean and micro computer does not seem to be fried (correct control of the 1 digit display)

I have to look deeper and therefore  desperately looking for schematics and service manual

If someone could help me it would be deeply appreicated

ps : the little story. The maintenance guy from Kone came and after a while said that nothing could be done except replacing the door operator by a new one : 3000 Euros ! (the complete door had been purchased 4 years ago for 4000 Euros)

Thanks by advance

: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.)
