Alan, thanks for the tip! Usually I loose micro springs like that but those
can be easily find by a magnet :-)

No, that's all right, I was laughing about myself as I realized how couldn't
I get the point of reading the documents :-)

Yes, I am playing with 16F627 for quite a long now, but for the app I wanted
to make needs to be as small and light as possible - that's why I thought of
10F200 with the SOT package. Actually I may have lucky as I use only one
input and one output lines and as far as I concern both can be connected
directly to the chip. As both line has already equipped with a connector my
plan is that I just put an extra pin to the MCLR so that I can give 13V to
that during programming. With this way I could easily connect the whole lot
to my ICSP socket of my programmer -- or did I miss something obvious?

Thanks
Tamas
