Actually, I was looking for this information for 3 years!...now thanks to you, the manual is on my hands and of great help, cause I understand now where I was doing wrong connections and wires...excellent, I'll be back to you if in need, thank you.
This manual covers the main equipment features only. While it also includes the procedure for saving and loading from the now long obsolete memory cards it does not mention the how to operate with the optional floppy drive interface so I am still at a loss about how to use this! Note that there is a separate manual covering the MIDI interface and programming via the keyboard, not included in this download. You will also need to get hold of this if you want to use the MIDI interface properly. Basically there is little difference between this manual and the free to download manual for the similar PR60 model.
Good list of manuals. I found a very rare one and easily get. Should be promptly to download, as we must to wait hours even after confirmed payment.

Main Features of the ep-90/70
Authentic piano performances
High-quality concert grand piano sounds, and a keyboard that�s a true pleasure to play assure an even more realistic piano-playing experience.
� Captures the brilliant resonance
The sound of a grand piano has a more brilliant timbre than that of an upright piano. This is because the sound of a grand piano contains a greater amount of high-frequency components. The piano sounds of the ep-90/70 reproduce this characteristic of the grand piano.
� Reproduces the extended high-frequency response
One of the features of the acoustic piano is that for the approximately one and a half octaves at the top of the range, there is no damper to restrict the vibration of the strings. This allows the vibration of the string to continue whether or not the damper pedal is pressed. Since this also allows these strings to vibrate sympathetically with other strings, they can sometimes be heard sounding independently from the low and middle-register strings. The ep-90/70 faithfully simulates these characteristics of the acoustic piano.
Eight Tones for use in a wide variety of musical genres
The ep-90/70 features not only piano tones, but eight different internal tones that you can use in a variety of musical genres.
Three Metronome sounds
The ep-90/70 provides a metronome that lets you use three different sounds. You can easily adjust the tempo and time.
Record your own performances
The ep-90/70 makes it easy to record your own performances.
