Weird RAM

I've got a substantial number of these, if anybody wants 'em. They're 18-pins, BTW, and were customed up for the Apple-III. I've got a memory board that uses 'em, but never got around to doing anything with it. However, that's how I learned where the rather odd DRAMs went. There are two rows of these guys on the board, together with a corresponding row of the 16Kx1 parts. IIRC, the rows are two-byte-wide rows. The board's clearly marked Apple-III, but in order to fit the intended application, I removed the connector which fits a pair of single-in-line rows of pins onto which the board plugs, probably toward the front of the main board. I've never looked at an Apple-III, so I can't comment on its role with respect to system function, i.e. it may be an expansion board, or perhaps not. These parts are normal parts, just as labelled, but have extra nRAS and nCAS signals with which to control the second chip on each substrate.
