[BBC-Micro] Batteries in a Master

[rafg1 at bigpond.net.au]

Hi Kris and all on the list,

I have bought at least one Master from the UK, importing it into Australia 
with only one battery (1.5 V Alkaline) and as I can best recall, it was 
sitting in the same spot that yours was, Kris. The battery wires were quite 
taught also, being barely sufficient to reach the plug site.

It retained its CMOS settings, worked properly and the seller mailed me 
later when I queried this, saying that one battery was "sufficient".

Best wishes

Raf
