Possibly, but it'll be on A1 paper :/

I actually know where these are in the cupboard, so...

The Acorn dual-socket boxes have no components inside - although there are 
mounting holes in the PCB for termination resistors and a capacitor. That's an 
issue 1 box, p/n 0239,000.

The Acorn single-socket boxes are the same PCB as the dual, but with only one 
socket (and in the example I have here, with termination resistors fitted - I 
suspect all the single ones are like that as I believe they're supposed to be 
used that way.

The SJ dual-socket boxes don't have any components either, but lack any kind 
of mounting points to even fit them - I seem to recall that SJ lines were 
terminated by plugs rather than within the boxes.

Thus endeth the lesson :-) Happy to trace out diagrams if needed - it'll only 
take 5 mins.

cheers
