So I'm trying to set up a bit of code involving a 4-bit input with 
outputs that need to dispense coins..

There are 3 different types of coins and I need to be able to drop out 
1, 2 or 3 coins of one colour along with 1, 2 or 3 of another colour.

It also needs to dispense 1, 2 or 3 of any colour by itself or one of 
each.

I'm struggling to be able to multiplex the inputs so that I can get the 
sufficient outputs.

Any ideas appreciated.

> set up a bit of code
What kind of code? Basic? Verilog? Pascal? C? VHDL?

Draw a picture or a table and try to show what you want. I cannot figure 
it out up to now...  :-/

All in all: lets see what you already have.
Nobody here just wants to do somebodys homework...
