I found these details in an envelop while going through my boxes. I'll open a general thread to see if anyone knows anything more about what happened to this set of add ons.

The Tangent sounds like more than an add on. It seems to be 'throw out the Dragon motherboard and start again with a Tangent system.

Fascinating! Never heard of it - and reading between the lines, it's not clear it was ever actually built. It seems more like he was assessing interest, to see what people wanted from such a system. I wonder if Geoffrey Barry is still out there somewhere? I shall hunt!
