Good afternoon,

I was wondering if anyone can give me some ideas on how to take an8-bit number and display it on 3 LED displays.

I would be extremely grateful if you could give me a push in the right
direction.

many thanks,

Sean

Pick an EPROM, preferably cheap. We will program about 1 kib. Shift
up your 8 bit value (or not, bit position
is not that important here) you need a 2 bit counter to cycle the
addresses for readout. Encode the translated
value to the 8 bits to directly seven segment displays. Use state 00
to read the value and the succesive
states to display the three digits. With an oscillator, maybe half a
dozen parts.
