Hi all,
I have now received the backplane components from Tony, and ordered the
extra components I need to complete the PCBs. They will be available in
approximately 3-4 weeks.
I anticipate they will cost about £45 including SH.
I'll post full details when they're ready.
I'm also waiting for

Is it an Mplane that was used in the AT cased version of a QL?
Any backplane is possible.

Hi Tobias,
thanks for your thoughts on this. And your guess on Pennell's solution
is correct :) Very interesting piece of information about driver
shadowing. Obvious, once you think about it but I hadn't thought
about it :)
Cheers,

There is also documentation on backplane power adapter (I think) on Dilwyns web
here http://www.dilwyn.me.uk/docs/manuals/qplane.zip from here

This is not a Qplane but a CST Q+4.

Hi all,
I have been asked off-list if I could make some backplanes. I have a stack
of the connectors already, so, if there was demand, I could do this quite
easily.
The questions are:
Is there any demand for this?
Is there any deficiency or design issue with previous ones that needs
correcting?
I would be interested in buying one. The DIN connectors seem to be
rather expensive so I'm a bit concerned about the price. A kit instead
of a finished assembly would also be nice. Four slots would probably
be optimal for my use. Can't answer your other questions since I have
never used one before
