In practise, I find most 14-bit PICs to be quite similar, the major
difference being what peripherals are included or excluded.
Since your application used the 16C84 I think you could find a modern
day replacement and implement your application on it with only little
effort, certainly without any training course.
A quick read over the config registers for the peripherals in the new
chip and maybe a few bits changed in your init code and you should be
good to go.
In case you need a real long-term product as part of your application
I am sure you can negotiate extended lifetime availability with
Microchip for certain parts, but I imagine they will in turn require
a MOQ per year committment.
The 16C84 product is more than 15 years old. I do not think it is
realistic to expect a drop-in replacement to be available. It is
amazing how close the 16F88 comes.
