Of course whilst all this work in the fields of languages, algorithms 
and such like has been going on, in parallel engineers have been working 
on the hardware side of things.  My understanding is that some abacuses 
now have as many as ten strings on them.  Although this scale was at 
first difficult for the users to grasp, the designers came up with the 
fantastic idea of using different coloured beads on different strings to 
simplify the user experience.
