This is further complicated by the Acorn tuning twiddlies being
extremely 'loose'. If they had a little bit of stick to them, you could
set a frequency and that'd be good. However with the Acorn adaptor, you
almost fear moving the unit could throw off the tuning!

Is it based upon the SAA524x? It always seemed to me to be odd that the
Acorn adaptor was built around the older first generation system rather
than the EuroCCT? Perhaps the original design dates back to the Atom?
