Not even $ instead of £?

Did you finish any of them?

No, not yet. I developed a flexible framework to support up to 8 distinct, user-selectable country key-maps (for a given firmware image) but only made a start on the actual mapping data for a few European KB layouts. So, at present, only UK and DE layouts are actually fully baked...

Hi

Generally, the # symbol is called a Pound, and the $ is above the 4 Key?


Regards,

The ASCII code 96 for £ was something specific for British-made computers. Apart from Sinclair, only the Acorn machines used it as far as I know. On standard ASCII it should display as backquote (`). So the backquote sign is not available in QL ASCII.

Back in the '80s there were systems that had the £ at ASCII 35 (originally #), # at ASCII 95 (originally _) and _ at 96 - notably Teletext which was a Britisch invention. So again the backquote sign was sacrificed to get a code for the pound sign which would fit into 7-bit ASCII.
