Well,

I can't answer your question, but I need some Info buy myself.
I just bought an MC board with the AT98S8252, and I'm a complete beginner,
So how do I go about programming it???
It is on a board together with an 82C55A. What is that chip there for?
There is also a 74HCT00N and a 74HCT 573???

Some advise for the newbie would be greatly apreciated.
