    Not convinced, ;) It doesn't look like the quad board goes all the way to the edge. The measurex board does look very similar to a quad QBUS card.

    I don't think that is QBUs, the two parallel metal bars would prevent QBUS cards being inserted, it certainly looks that way to me from the photo.

    Thanks gslick, I hadn't found that so I'll file that away for future use. It doesn't cover the EE variant. My thinking is that EE is a later version of AE UK keyboard but I'm looking for confirmation.

    LK201 Keybaord

    As far as I'm aware the LK201-AA is US keyboard and LK201-AE is UK keyboard. What is LK201-EE? It has UK pound sign on 3 key as with LK201-AE.
