Roland Memory card M-256E Rare Vintage Card R70 R8 M256

Original rare memory card, good condition, as used in Roland Human Rhythm composers etc. I'm told it will also work in the following, though that's hearsay.... I can't swear to it. JD-800, JD-990, JV-80, JV-880, D-70, D-50, D-10, D-110, D-20, D-5, D-550, R-8, and any other unit calling for the M-256E (or D) RAM format.
It also works in all PEAVEY synthesizers, Tube-EFX etc., and RODGERS 905 Organs

Guaranteed to work or money back (though these do use an internal battery that you may need to replace).
