The BBC User Guide was the primary item of documentation supplied with the Model A and Model B Microcomputers.
Provisional User Guide
In the first few months of production of the BBC Micro, the main user guide had not been completed, so a Provisional User Guide was included with the machine. A postcard was included in the box for owners to register for delivery of the full User Guide once it became available.
The Provisional User Guide was printed in a single colour and had large sections missing - particularly content covering programming and the detailed syntax of many of the BBC BASIC commands.
