Some time in the next few weeks, I will be cataloguing it and adding it the
Chris's Acorns. I will include HiRes pictures of the circuit board (these
will be at the maximum resolution my camera  - Cannon PowerShot S30 allows).

Getting a ROM image may prove harder as I haven't done that in years and
will have to find the software and maybe EPROM programmer. But I'll see what
I can do.

Joel is right about it connecting via the 1MHz Bus, not the Tube, the plug
is nicely fits the 1MHz bus, but is too same for the Tube.
