if you turn on your beeb and get a single 1 second low beep but no the following high beep, this is fairly common if your keyboard is not connected or faulty the bbc micro waits until the keyboard returns the dip switch settings before booting check your keyboard connection and keyboard unit is sound this can also be if any of your roms installed in the system are bad, or perhaps do not work with the system configuration (such as installing a dfs 2 26 rom in a bbc micro without a 1770/1772 floppy interface ic (as the code checks for that and hangs if it is not found) a good test is removing all roms and booting with only the os rom
