Hi,

The more I get into these things the more I realise how much I have to
learn from you guys.

I have developed various bits of code (LCD, Switches etc etc) and have
them running on a PIC16C84.

My application demands lots of I/O (about 20 pins in all) and I want to
move to something with more I/O instead of adding extra external
hardware (serialisers etc etc)

Does anyone have any advice on the pitfalls involved in (say) moving to
a 16C63 ?

For a start I know the 16C6x devices only have a 2-level stack whereas
the 16C84 has 8-levels.
What is the best way to partition and test the software on the 16C84
before moving onto a new device.....
