Shots of the inside below.

"Well here's something that you don't get to see everyday! This is an extremely rare specimen of one of the actual first digital keyboards sample type machine made. This is an R.M.I. DK-20 Digital Keyboard. These came about in 1979 and were only made till 1980. So, for only one year these were made!

This machine is equipped with 4 EEPROM IC's similar to what you find in Oberhiem, 360 Systems, and Sequential Circuits instruments. These EEPROM's hold the instruments Timbre's (voices). These voices can be selected via the 4 yellow buttons located in the Timbre section. There's also a "Preset" section that includes: Tine, Clav, Lute, Jaw, Fazor, and Piano along with a variation of each one preset as well. These presets are of course, dependent upon the EEPROM chip set as well. You also have a whole set of phaser effects, three modifiers, a mixer section for each one of the Timbres, Vibrato with switches for rate, TRS control (a kind of mild ring modulator). It also comes with a mono output, and separate bass and treble outputs for stereo connection or running effects on different sides of the instrument. You can also hook up a standard sustain pedal. It also comes with very sturdy steel fold-up legs that are attached to the unit. and a cover that snaps to the top to keep it covered when not in use. There's also a simple sheet music stand.

This machine is FULLY FUNCTIONING!! 100%. Cosmetically I'd give it an 8 out of 10. There is a few scratches here and there which you can expect along with an engraving on the left side of the key-cover for a school system this once belonged to dated 1981-'82. The machine was made previous to this but this is when the school owned it. The inside is immaculate and completely free of dust."
