Pounds, shillings and pence calculator

Sterling calculator
Introduction
Sadly, electronic calculators arrived too late for Britain's pounds, shillings and pence system. The first calculators went on sale in late 1970. Decimalisation was already on the way in the UK, so no-one made a sterling pocket calculator.
I wanted to see what one would have looked like if the technology had been available a little sooner, or if we had kept pounds shillings and pence until 1975.

seems to have stopped working, but is so good when it does, invaluable in helping me work out wages and allowances in 1930s for my dissertation, any plans to fix it? thank you
I'm sorry you are having problems with the calculator. Please give me an example of what you mean by 'stopped working'. It's not been changed.
I've tested it on Chrome, Safari and Edge and it seems to work for me ok. Please tell me which browser and platform you are using.
Great - but it seems to have stopped working? are there any plans to sort it out? so useful to me in working out wages and allowances in the 1920s and 30s for my dissertation! thank you
An absolutely brilliant device. I've just found my grandmother's old grocery book from 1960's, worked out in pencil. The calculator's subtraction feature gives correct change for the money tendered.
Is there a percentage calculator like this anywhere? You know, with pounds, shillings, and pence..?
How do I calculate percentages (for finding VAT)?
