I am having a serious problem getting started with the 16F877.  All the
pins are pulled low (~10k resistors to ground) except for VSS and VDD,
which are respectively connected to ground and +5V (coming out of a 7805,
with a few caps to level the voltage).  Yet the chip draws around an amp
and starts heating....  It's as if the VSS and VDD pins are internally
shorted to each other.  I'm positive that everything is hooked up as
described; e.g., I didn't swap the supplies to VSS and VDD, causing a short
through the protective diodes.  While I suspect that I've toasted this
chip, I'm wondering what I did wrong, in the interest of not toasting
another one.  I'm also very curious what could cause such a critical
internal short.

Thank you, and have a happy new year!

Jake
