<DIV><FONT face="Arial" size="2">I'm hoping
to use the 16F877 for my initial development, then move up to the 18F452,
it should have enough memory to handle IP, xPL and still have&nbsp;more
than enough&nbsp;space left over to actually do useful
stuff!</FONT></DIV>

<DIV><FONT face="Arial" size="2">POE is a
definite requirement, but Cisco's probably isn't... it's the opposite
polarity to everyone else!</FONT></DIV>
<DIV><FONT face="Arial"

<DIV><FONT face="Arial" size="2">That being
said.. I have this idea that if I use a bridge rectifier on the power
inputs, it will automatically give me both polarity protection for DC
power, and also rectify AC power, so *in theory* with some clever component
selection (max reverse voltage etc) </FONT><FONT
face="Arial" size="2">I could run off of Cisco +-
48V DC, Intel -+ 24V DC, or Homebrew -+12V AC</FONT></DIV>

handy!</FONT></DIV>
