Sure.
But since the 'product' is software based, there is no good
reason to NOT keep it up to date, given that the changes
in the newer chips is a slight change in the way that programming
is done. They only have to support the few commands that ICSP
requires. Set address, read, erase, program, bulk erase.
The drivers for the ICD1/2 are already written. They only
need build the data tables for the new chips.

Microchip, what is the REAL reason you have stopped supporting
ICD1 & 2? Whatever happened to 'the customer is usually right'?
