I saw one go on eBay for GBP 750 start of last year ... there are a few
kicking about.

I have an original acorn terminator box that was converted to be a clock
(they had same PCB inside, populated differently) in a non-standard way -
this one seemed to use not much more than a 555. I'll try and dig it out
and trace the circuit, if it would help. Replacement terminators were not
much harder to make - three or four resistors in the back of a 5-pin DIN
was enough. I was never quite sure what the one acorn supplied needed a
PSU for ..! Cabling was simply daisy-chain the BBC's in parallel.
