Ultra Rare Casio Dm-100 Vintage Dual keyboard TESTED Holy Grail. Sampling

  

Ultra Rare Casio Dm-100 Vintage Dual keyboard - TESTED - Holy Grail. With that said, this is a fully functional sampling synthesizer keyboard with no signs or damage. Two of the volume slider tabs are missing as shown in images.

This this is so rare that after hours of research, I have found no significant information or any availability besides one, it seems, from Brazil. I have not tried the sampling functions of the unit. But have no doubt it's working. There are scratches on the base and back from what seems to be normal use. I have inspected all the screws and I feel pretty confident that this unit has not been opened or molested by an armature.

I have only tested it with a variable DC power supply to the 9.0Volt 7.0 W requirement and not the D-Cell batteries. The battery port looks clean and doesn't seem to have any old battery leakage residue. The spring inside also looks to be in good shape free of corrosion. I will try to procure a power supply but I cannot guarantee one. Speakers are crisp, but there is a minor rattling from the low notes when volume is on full. I will gladly send more images or video/audio to anyone interested & answer any questions you may have. I only cleaned the keyboard lightly to make sure I don't damage the writing on it. This unit is 30-35 years old from what I can tell. Casio SK-1 SK-2 MT-40 SK-5 HT-700 MT-70 PT1 PT-1 Pink.
