I suddenly got it into my head to do a type of shot I haven't done for 15 years.
So, having spent hours digging around in the loft yesterday, I emerged with a BBC B computer and several boxes containing homemade circuit boards, batteries, pumps, tubing and wires, wires, wires.

So, trial and error it is. The computer still works and the interface board too. I am reduced to taking pictures of the program listing on screen, printing them out and puzzling over what does what..
