and still only able to add. The internal workings
are similar to the earlier model A. |

| The half keyboard design allows experienced
users to operate the machine very quickly,
pressing two keys where necessary. |
| |
| Designed for £sd sterling and including
farthing and halfpenny keys, this model was
introduced in 1960. |
