I don't have a Blue Box to put my  3C into yet, but when I do I assume it will matter 
which end of the BackPlane5  the 3C front panel plugs onto.  

Should I put the 90° (flat socket)  connector on Slot 1 or Slot 5 ?
 
I can't find  a picture of a 3C installed in a Blue Box which would probably make it clear.

Thanks,

PeterO

Replying to my own question ....

Having "buzzed it through" it has to go on Slot 5, but I don't think that is stated
anywhere.

Hi Peter,

You're right, the right angle socket should go in to slot 5. There are
some good photos of that setup on the Orton 3C listing on the z80kits
website https://z80kits.com/shop/rc2014-orton-3c/

Cheers

Spencer

Thanks Spencer,

Somehow I failed to look on the z80kits site.
I'm just about ready to test it out, so time to go and read up on how to drive it :-)
Note I've put the ribbon cable on the right way round since I took that picture !
