Back in my mis-spent youth my family used to have a BBC model B. Recently, I bought my fatherr a secondhand RISC PC and shipped it to New Zealand. It worked on arrival, but he's done something to damage the install on the hard disk, and now it will only boot up to the '*' (supervisor?) prompt.
At this prompt, the keyboard auto repeat rate is impossibly fast, so he can't do anything to install the system. As the computer is now on the other side of the world, I can't really go and investigate in person. Does anyone know why this might be the case and what can be done to slow it down so the prompt is useable?
