BBC Micro, Sinclair, Old Home Computers (Trimley St Martin IP11)

Hi, I want to get back in to an old hobby of mine, restoring and running old 1980s home computers. I would also be interested in any add-on devices, books, software it does not matter if they are not working. I can also make sure they are electrically safe to use. I primarily interested in BBC Micro, Master & Sinclair computers, but also interested in other makes and models. If you have any in attic or storage just sitting there, please get in touch. I can collect around Felixstowe, and Ipswich but will travel further afield for something more interesting
