Hi dominicbeesley,

In case your FPGA kit have not enough RAM, you can use external IC RAM like 4164 ( RAM about 8Kbytes) and just add the missing code to drive it.

You'll need at least to have 28 pin for the IO signal.

The total code is around of 30 k0.

DON'T FORGET TO ADD IN SERIE RESISTOR TO PROTECT the IN Pins.

My design run with a clock of 50 MHz.

It'll be better to work with a clock of 100MHZ.

Let me know what kind of kit you hve.
