We hate 2020!

Just when we thought 2020 couldn't get any worse! We were about to re-open after many months of being closed but then disaster struck when a mains water pipe burst and flooded much of the ground floor of the museum.
Sadly re-opening has now been postponed. Read More >>>

Casio AQ-1000 Calculator

This is one of the early LCD clock style models from Casio. the low power consumption of the display means that the time can be continuously displayed whilst in the watch mode, a switch selects between watch and calculator, the latter also having a stopwatch with lap feature. the switch was eliminated in the later AQ-1500 model which also added date capability but appears to have lost the alarm feature. It is an arithmetic calculator with 8 digits precision and algebraic logic. It has 6 functions, 28 keys and one of the early LCD (liquid crystal) displays which incorporated a yellow filter. The power source is 2x1.5V cell. The calculator was manufactured in Japan.
