Where 6567 fits
Why 6567 is special
Programmers found that changing its registers mid-scanline defeated its own documented limits, producing effects the designers had not intended or anticipated.

In historical numeral systems
Egyptian
6 lotuses, 5 coils of rope, 6 hobbles, 7 strokes
6 × 1,000 + 5 × 100 + 6 × 10 + 7 × 1 = 6,567. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.

Related numbers & connections
Both provide hardware sprites; the VIC-II was routinely pushed past its documented limits by raster interrupt techniques.

Media & popular culture
The 6567 and its PAL counterpart generate the Commodore 64 display with hardware sprites and multiple graphics modes. Raster interrupt techniques exceeded the documented sprite and border constraints.
