"Included are the original manual, MIDI specification booklet, and two ROM soundbank cards in their original vinyl protective sleeves — the standard RC-100 card that was included from the factory, and the increasingly hard to find RC-110 "US COLLECTION". NOTE: The power supply is for 100-120V 50/60 Hz power only, and I'll include a normal grounded power cord for a buyer located in either USA or Canada.
Also, while this synthesizer module is in very clean condition (among the cleanest specimens I've seen actually) it is not strictly "mint". I've circled some minor scuffs in the finish in yellow in some of the listing images, so please look carefully — some of them I was hardly able to capture with camera and were otherwise something I had to really look for, but I also wanted to be absolutely transparent about the condition of the item you are buying. The display remains reasonably bright and easy to read, and is also free of scratches (as is the rest of the faceplate). There isn't even noticeable rack rash on the ears. The owner's manuals are in good, very readable, unmarked condition but the cover flap on the owner's guide is a bit torn at the bottom and like the MIDI spec guide exhibits some shelf wear.Honestly I think this is in many ways a more charming synthesizer than the original Yamaha DX-7, for which this synthesizer along with its keyboard cousin (the VZ-1) were Casio's answer on the market to. The quality of the individual oscillators is (imo) noticeably better, there's ring modulation, and the timbres rawer and somehow "dirtier". It's noteworthy that sound output on this module is a bit crisper and quieter than those of the VZ-1 (and yes, even the DX-7). With the right timbres through a quality reverb, this could be a lovely instrument. Sadly, I no longer play."
