$10 is pretty expensive for a lot of applications. I bet that processor also uses a lot of power and takes up a lot of board space. If you've only got $2-$3 in the money budget, 200uA at 1.8V in the power budget, and 6mm X 6mm of board-space, your choices are limited. Besides If you can get by with 256 or 512 bytes of RAM, why pay 4X the price for a 1K part? Besides which, the 8032 instruction set and development tools are icky compared to something like an MSP430 or an AVR. ;) [The 8032 is still head and shoulders above the 8-bit PIC family.] -- Grant -- http://mail.python.org/mailman/listinfo/python-list
