I used this item for many years in my home studio. I was running Mix Farm and Mix Core cards in a Mac G4. I have not used it for some years but it was in full working order when I packed it away. If you are interested, maybe you'd be interested in the cards too (see photo). This is very old tech and I've tried to reflect that in the asking price. I welcome any questions and will answer to the best of my ability.
