I didn't look at that, mainly because I'd use it as a control box for the
multifunction timer in an electrically powered free flight model
aircraft. I was planning to do the graphics with GTK2 front-ending C, but
I see that the recommended graphics is the Kivy framework, which only
seems to have support Python bindings.

However, bearing in mind that a bog standard VGA screen is/was 640x480
pixels, so this is effectively a somewhat wider VGA screen. A VGA display
in normal text mode displays 24 lines of 80 characters, so the equivalent
mode on this would be a 24x100 display, with characters drawn in
something like an 7x16 matrix. Total line height, including the
whitespace between lines, is 20 pixels.
