Beginners Guide to Interfacing the BBC Microcomputer details several electronics projects that can be connected to and controlled by the BBC Micro. The book covers connecting devices to the User Port and Analogue port and includes a project based on Technical Lego.
This book has far less explicit hardware instruction in each project than "Interfacing projects for the BBC Micro" instead providing type in programs that draw the project assembly images on a BBC Micro itself. The book redeems itself in the extensive descriptions of the User Port and Analogue Port.
