Ooer, don't say that....there used to be *lots* of them at radio rallies, 
but I haven't been to one for a couple of years (planning on doing Elvaston 
Castle this year though).

I suppose I could always make one, assuming the necessary ROM images are 
available somewhere? I don't recall there being any custom logic in the 6502 
Second Processor and my memory of the Torch Z80 2nd processor is waaay to 

Which brings me onto a second point. I actually have at least one BBC 
"Master" too, I have a vague recollection that these have a connector for an 
internal, as well as an external, second processor?

Do you know of any websites where I could get more info?
