It is a bare board, and he came to me to borrow my Tarbell manual so he could put his board together, and we find that it's actually a Vista disk controller. It turns out that Tarbell licensed the design to Vista back in '77. The board seems to be slightly different, with the addition of a couple of IC's where the Tarbell board had spares. Tarbell has no idea what Vista did with the board once they licensed it from Tarbell, and the people at Vista had no idea what I was talking about. Any information detailing the differences between the Vista controller and the Tarbell controller would be greatly appreciated. Roger Long ucbvax!ucivax!csuf!bytebug
