Be sure to add me to your favorites list Original Yamaha Color Brochure from the Early 1990's, RY30 ROM Sound Cards, 2 Pages (1 Page Front and Back), Printed in Japan This is a nice full color brochure from Yamaha, as unusual one, as it's for some interesting accessory ROM cards. This brochure shows the 8 ROM sound cards that were available for the Yamaha RY30 drum machine rythum composer, though they could also be used as sources of waveforms / sounds in other Yamaha units that took ROM cards at the time (such as TG500, SY85, etc.) This is in overall very good condition, with some minor wear and finger indentations. There are 2 pages of photos, 1 page front and back, along with information on 8 different ROM cards, 4 Standard Series and 4 Artist Series. It has some nice photos, along with the wave list, voice list, and pattern list for each individual sound card. This is a very collectible Yamaha brochure booklet, the only one of these I've ever seen. From the very early 1990's, printed in Japan! This is a manual or document, this is NOT a piece of equipment or instrument. If you have any questions, I'm always happy to answer them. Thanks for looking! Check out my Store!
