At the advanced Vhdl course the practical was done on a ALTERA chip I used the code handed to me as a starting point
it had the basic timming for the board the project for the course was to make a clock on a vga screen here is what I
got as a starting point.

 My aim was to keep the addresing as simple as possible and use a font 8*8 only capital letters I also wanted a simple way of displaying hex values
so I the font use 0-F produce a 0-F on the display .
