Ncr7250 #15

Closed robcfg closed 1 year ago

robcfg commented 1 year ago

Default font of the NCR 7250 CRT Controller.

The font is in a rom area inside the chip, which is not accessible through software methods, that was customized for NCR clients. So, potentially, every 7250 out there can contain a different font.

The font is stored as 8x12 characters but the chip copies the first column to be to the right of the rightmost column, and if the arabic text attribute is set, then the first column will be duplicated and put to the left of the first column.

This default font was extracted from the datasheet of the chip.

I manually one or two fonts from datasheets and thought it was rather a lot of effort, so thanks!
