The setting of some jumper links on the back of the display PCB?

The ones I've seen basically had links which allowed each segment to be 
in one of 4 states : 

Always off
Always on
On in turbo mode, off in normal mode
Off in turbo mode, on in normal mode

You could 'program' any pair of patterns to be displayed. SLo and FASt were
not uncommon.
