I have sent a reply to the couple of people who have asked for copies of my code but I am writting some documentation to go with the code which should allow easy implementation(ha!) and explain how to connect the cpld to the sdram and so on rather than sending individual copies of the code and documentation I will post them both on my 8052 page and people can download it from there as and when they want,also it gives me a day to check that a change i made to the code still works:-)So watch this space I shall do some tonight and hopefully in a day or so.I think i should chage my name to Bill Gates ,it could be called SDRAM millenium
