Be sure to add me to your favorites list ORIGINAL CASIO MT820 ROM PACK KEYBOARD OPERATION MANUAL This is an original owner's / operation manual for the Casio MT-820 mid-sized ROM Pack keyboard. It is in good condition, and is complete and very helpful. It has both English and Spanish sections. Use of ROM packs, tones, auto accompaniment, chord memory, effects, specifications and more are covered. This would also be very helpful for the MT-800, which is very similar, just with the speakers separate from the keyboard (they are detachable). This booklet has a cover that's a bit yellowed with age, and there is a slight remnant of a stain in the upper right corner on the cover and a couple of the pages. This manual will be very useful for the MT-820 player and great for the Casio keyboard collector too! This is a manual or document, this is NOT a piece of equipment or instrument. If you have any questions, I'm always happy to answer them. Thank you so much for looking!
