You know, this 12F509 has an internal oscillator....is this a problem for most of the programmers?

Like I say, I don't keep up with all the part numbers and not a really frequent picbasic user.

I think I should look at another part number that is compatible with my P16pro40 and forget the 12F509.

Could anyone suggest a low cost, (2 to 2.50 neighborhood in quantity), basic PIC that is anywhere from 8pins up (actually the more I/O the better, so 14 to 18pin is no problem at all).

Nothing fancy, just need some I/O pins to work with and an external xtal or rc.

A flash part.....still vailable in a dip packeage and definetly COMPATIBLE WITH THE P16pro40?

THANKS kindly for any part numbers....I'm just going to send these 12F509 back.
