I would certainly be interested also in a kit of parts and instructions for a
monitor with all those functions.

Which functions?

Actually, I'd like to know if more than 8 bit resolution really is needed. Unless
you want to make an altimeter, why would you want more than .5% resolution? Do you
really care if oil pressure is 59 or 60 psi?  Or temperature is 200 or 201 F ?

That's a fallacy Finn. When push comes to shove it is a lot harder
to set the dynamic range so you take full advantage of 8 bits or one part in 256.
Yes I know it can be done and 8 bits in theory will work fine but....
It so much easier if the dynamic range is 10 bits or one part in 1024.
Take EGT for an example three digits or four what would you choose?
The hot tip flash PIC 16F877 does ten bits anyway why not use it?
It is only a few bucks more than a 80C35. I vote for ten bits.
