        I have a problem here, which I hope you guys can help me 
with.  I need three things:
 
        1)  a 7segment displays(3 or 4)/decoder/driver - this 
driver needs to have an 8bit(for a number up to 256, hence the 3 
displays) input.  driver needs to convert these 8 bits 
into the corresponding digits(up to 3) and output them on the 
displays.  The driver can be a multiplexer, or an equivalent.
 
        2)  a programmable countdown/timer(must be programmable 
with 8 bits).
 
        3) a countup/timer with 8 bit output(to drive the 
multiplexer or equivalent above.)
 
        Thank you, any information(sources, chips, etc.) would be grateful.
