Sinclair Technical Information Sheets

Sinclair's service department was also responsibe for answering technical enquries. When you are selling to a home-constructor market, it soon happens that the same questions get asked many times. So we had a series of Technical Information Sheets to answer these standard questions.

I still have copies of some of these sheets as listed below. Please ask if you need details.
