We will learn later if we built the said project. But I am already learning so much from this topic postings.

I think we should continue debating on this topic. Everybody here says something right from his own point of view, and I personally respect all inputs as they all are innocent guidelines in their own.

One can see, that my idea is a workable and genuine idea, otherwise we were not here to discuss so much about it.
Honestly, Henk is absolutely correct, that my intention (and the real idea) is to make a system or project where one can spent his/her time for developing skills on the area where he wants to go for. I can take my example, that I am not very much experienced in this field (I can not say me a 'begineer' though), when I wanted a programmer for flash chip, I purchased it, did not spent time for building it up. it is not because I was lazy but my actual project was not allowing me to spent time on building a programmer. I will learn this at some later stage, when it will be feasible for me. similarly, as we all know that we have to built a prototype with many sockets and some keypad interfaces etc for our own prototyping excersie before finalyzing the layout in our project, so why dont we have a universal prototyping station, where we do not need to solder keys or keypads, other interfaces etc.

If someone can show me how to overcome this problem, I will be glad.

I specially thanks to Jay, as he is just not guiding us for 8052, but he is also consulting us on business side, which is the ultimate game (most of the time).

Peter and steve seems busy this time. Hello peter and steve.

Thanks to every one.
