Need an Owners Manual / Users Guide / Operation

You can download a manual for the Casio MT-35 keyboard from the Casio website.

try this... Casio Casiotone CT 360 Manuals ..or this... Casio CT 360 keyboard manual Google Search

Some Casio Keyboards use 9V DC (center negative) others 12V DC (center negative).
If check what voltage your Keyboard use. Generic AC adapters are usually center positive. So you have to invert the wire with a new DC plug to make it center negative,
Easiest is to buy a Casio ac adapter made for your keyboard from a Casio retailer.

Yes I have one which I can photocopy for you if you are still looking. I appear to have lost my Power Adaptor and would appreciate knowing any Name or reference on yours if you have one.

My e_mail address is [email protected] if you care to contact me.

Thanks.

I went there as well casio.com/usa I would try the MA 150 many times the instructions are very close to each model. If this still wont help, try Ebay and Yahoo there a lot of manual collectors there . You may even get lucky on YouTube good luck DFD please rate me
