The cognoscenti come up with useful information spread around, showing
that there are a bewildering number of "backplanes"; how could a
newcomer easily find this?
I still don't know what sort of backplane the original enquiry, asking
who would buy one, referred to. I must admit that this is an academic
exercise, as I wouldn't expect to buy one anyway.
There is really only one 'backplane' - a device that adds extra
expansion plugs to the QLs expansion connector (sometimes called 'J1' as
that is its label on QL circuit diagrams).
Dave has not decided exactly what his backplane will look like.
In all probability he will just build some Mplanes from component stock
