He is also selling one item without RAM. Would be good to use it with one of my Tetroid CF/512k cards. Plus the 3 EPROM card, plus (sometimes) the QEP III

:D

Do you have to cut slots in the bottom of the QL and table to plug other cards in the back plane? :shock:

Nooooo, it plugs into the other whatsit that adds the RAM and basically extends the expansion port so that it's right on the external edge. It comes in 2 parts.

Would be interesting to see whether the board supports a GC/SGC on the backplane - these sometimes have unexpected data directions.

Would also be interesting to see if the backplane needs to be connected directly to the driver board or whether a piece of ribbon cable could be used in-between.
