One thing you need to be aware of on the ICD. If you use it, you can't use
the interrupt on PORTB change feature since Microchip in their brilliant
wisdom used the upper nibble of PORTB for the ICD I/O pins!

Now what you can do is wire up some Xor gates to give you a 'step' and
'direction' output from your encoder then hook that up to an interrupt pin.
But that defeats the purpose of having the interrupt on PORTB change
feature! So if you want ICE and PORTB interrupt, you'll need the Mathis, ICE
2000 or some other ICE and not the ICD.
